Muramasa Art & Incursio

{A/N: Since it has been a long time since I have updated a chapter because of my Midterm exam, let me update 4k words chapter as an apology, and don't forget to join the discord server for Picture, suggestion, and all the latest information and some new updates about this fan-fic: https://discord.gg/eCwmhXJ}

Shuri and Akeno who watch Tetsuya from behind closed their eyes when the blade is almost hitting Tetsuya. They feared that Tetsuya is going to get hurt. Suddenly when they opened their eyes, both Shuri and Akeno is panic when they saw a lot of blood that splatters around the floor near where Tetsuya is standing. But their expression changes when they saw that the one who attacks Tetsuya is thrown and attached to the wall.

Akeno who saw this has a blush on her face while seeing Tetsuya standing in front of her. Inside of her, there is an unknown feeling. She doesn't know what this feeling is but right now when she looked at Tetsuya who protects her, her heart is beating faster and she has a blush on her face. She then put her hand on her chest while looking at Tetsuya with a blush on her face.

Shuri on the other hand is shocked and her eyes are widen opened. She knows that Tetsuya has power since Anna told her, but to what she didn't expect his power is higher and more monstrous than what Anna told her that he can defeat one of the mask men in one move.

Suou and the mask men group on the other hand are so shocked that all of them have their eyes widen and jaw drop opened. All of them didn't expect that this would happen when one of them attack the boy. Suou then orders one of his followers to check the person who attached to the wall.

"Suou-sama, the guy who is just punched by that kid is already dead." Reported one of the mask men who is ordered to check the body.

Suou who heard this could only give a hateful gaze at Tetsuya who right now is picking the katana that is dropped by one of the masks men who just died.

Tetsuya who right now is picking the weapon that is just dropped by his enemies didn't feel anything when he killed one of the mask men, he feels weird when he doesn't feel anything when he killed one of the mask men but decided to shrugged it as he thinks it because of his system. Suddenly a notification appeared in front of Tetsuya.

-------------------------------

[You have killed a Himejima clan member. 5.000 EXP of [STATUS] has been acquired]

[Because of the title 'The one who will create a Legend', 5.000 EXP will be changed into 10.000 EXP because of the effect of the title]

-------------------------------

'Not bad, the effect of the title also follows as I kill my enemy.' think Tetusya while having a smirk on his face.

"Nice toy you got here, you old sh*t." Said Tetsuya while look and hold at the katana.

Tetsuya then uses his 'Weapon Appraisal' skill to check the weapon status.

-------------------------------

[Himejima Clan Katana]

Durability: 75

-------------------------------

Unfortunately, Tetsuya 'Weapon Apprisal' right now can only view status such as durability, because of his 'Weapon Appraisal' skill still low level.

'*sigh* looks like this weapon can only withstand my sword technique for only 5 or 6 times.' think Tetsuya while looking at the weapon with a frowned expression.

~~ FLASHBACK 2 Months ago ~~

After Tetsuya come out from the 'White Room' to eat dinner with his family, Anna suddenly comes in front of him and gives a piece of advice to him.

(A/N: This is the event after Chapter 12)

"Tetsuya." Said Anna while calling Tetsuya in the training room.

"What is it, mom?" Ask Tetsuya while looking at his mother.

"Just to be clear that, if you want to use 'Muramasa Sword Art Technique' with your mana, you must use a weapon that is durable for you to use." Said Anna while looking at Tetsuya.

"Then why can I use the wooden without breaking it?" Ask Tetsuya while looking at Anna with a confused expression.

"Well, that is because that is not a normal wooden sword, since your father has been enhanced every training tool inside this room so it cannot be broken except if I go all serious or all out." Said Anna while looking at Tetsuya with a proud expression like a wife showing off her husband to everyone even to her own children.

"Then, am I suppose to use a wooden sword as my weapon in the future?" Asked Tetsuya while looking at Anna.

"Oh don't worry about that, mom will make sure to make you a good weapon." Said Anna while looking at Tetsuya with a happy smile.

"Mom, you can make a sword?" Asked Tetsuya with a star in his eyes while looking at his mother.

"Of course not." Said Anna with a neutral expression.

"Eh?! What do you mean by that?" Asked Tetsuya with a dumbfounded expression.

"It's not me who will make it, but my family who will make it." Said Anna while looking at Tetsuya with a carefree expression.

'Hmm... Muramasa descendent, I wonder what kind of sword they will make for me. But if Mom doesn't want to make the weapon and she wants her family to crated the weapon, can I concluded mom as a good for nothing blacksmi--.' think Tetsuya when suddenly his head is being hit by Anna's fist.

"Ouch... why are you hitting me, mom!?" Asked Tetsuya with a teary expression while both of his hands are holding the swollen part of his head.

"Well, my hand suddenly just move automatically." Said Anna while looking at Tetsuya with a scary smile on her face.

Tetsuya who saw his mother smiling at him shudder as he didn't want to think rudely at his mother, as his mother maybe has a Rude detector skill.

"Well, I will tell you if the sword already finishes." Said Anna with a carefree expression while looking at Tetsuya.

"Okay." Said Tetsuya while nodding at his mother scaredly.

Tetsuya then goes to the training room to check the wooden sword with his 'Weapon Appraisal' as he wanted to try his new skill.

Tetsuya then checks the wooden sword status with his 'Weapon Appraisal'.

-------------------------------

[Wooden Sword (Enhanced)]

Durability: 15+1.500

-------------------------------

"Isn't this too incomplete for a skill." Said Tetsuya as he looking at his new skill 'Weapon Appraisal' with his mouth twitching.

Tetsuya could only sigh as he knows that his 'Weapon Appraisal' skill can evolve as he raises his skill level.

As for the enhanced part, Tetsuya is so intrigued as to how to use enhance.

'So that is the enhance part.' think Tetsuya while look at the number 1.500.

'As for 5 is the normal durability.' think Tetsuya while also look at the number 5.

'Maybe I should ask dad to teach me how to enhance.' think Tetsuya while thinking that if he increases the level of this skill, this could also boost his strength.

Tetsuya then tries to use multiple 'Muramasa Sword Art Technique' whiles using the enhanced wooden sword.

When he finishes experimenting with the wooden sword, he concluded that using the 'Muramasa Sword Art Technique' makes your weapon decrease their durability by 10 or more depends on the mana and technique he used.

After that Tetsuya goes to the living room to eat dinner with his family.

~~ END OF FLASHBACK ~~

'*sigh* I wish my new weapon is here. Well, Gram is a sword but still, it's not compatible with the 'Muramasa Sword Art Technique'.' think Tetsuya while sighing.

'Well at least I got to learn to enhance from dad, but right now I can only enhance my own body, well I kill that guy with enhancing my fist. Well, it's weird to learn to enhance the body first, rather than an object, well whatever, I can improve my skill later in the future so that I can enhance an object.' think Tetsuya while thinking about his skill.

Tetsuya then looked at Suou while also mocking him.

"Oh never mind, your weapon is like a piece of sh*t like you." Said Tetsuya with a deadpan expression while looking at Suou.

Suou who heard Tetsuya has an angry expression as some veins started to show on his head.

"Kid!!! Who are you?! How dare you kill one of my Himejima clan members!!" Shout Suou while looking at Tetsuya with an angry expression.

'Who is that kid? How can he kill one of my followers? Is he someone that disguised as a kid to make me and my follower off guard? Well, it doesn't matter, what can he do fighting alone against 37 of my follower.' think Suou while has a serious expression on his face.

"Hey old sh*t isn't it rude to ask someone name without introducing yourself, and you think yourself too highly old sh*t. You think all of your 37 followers will be enough to defeat me, What a joke!" Said Tetsuya while giving a smug smile to Suou.

Suou who heard Tetsuya is shocked and confuse, as He didn't expect Tetsuya to figure out all of his followers around the shrine since only a few people enter the shrine with him.

"Kid, can you tell me something, Are you under the influence of fallen angels that you tried to protect them. If so, I give you the chance to come to my side. I can give you anything you want if you join my side." Said Suou while trying to convincing Tetsuya to join his side.

"Hoo... So you're saying you going to give me anything if I join you." Said Tetsuya who suddenly let out his mana in his body while walking towards Suou.

Suou who feels Tetsuya mana is backing away from the place he is standing. All confidence that he has inside of him is nearly gone when he feels the mana around Tetsuya.

"Then can you give me your own death to me?" Said Tetsuya with a cold stare while looking at Suou.

"Y-you!! How dare you! I order everyone to attack that insolent kid!!" Shout Suou while ordering his follower to attack Tetsuya with a fearful expression on his face.

All the mask men then move toward Tetsuya who holding the katana weapon. All of them think they can bear Tetsuya as long as all of them work together.

Tetsuya who sees all of them about getting closer to him feels happy that he will get another free EXP.

Tetsuya then put a stance where he put the katana weapon around his waist before all of the mask men reaches him.

『Muramasa Art --』He then put all the mana that he let out on the katana weapon and infuse it with his weapon.

『Wind Scythe』When one of the mask men is about to hit Tetsuya, Tetsuya then uses the technique while unleashing all the mana inside the blade. The mana that unleashed within the blade has become one with the wind and forms the shape of a crescent shockwave.

When all the mask men see Tetsuya attack, they tried to dodge it by jumping or crouching. But because of the attack speed of Tetsuya sword technique, all of them still get hit by Tetsuya attack.

All the mask men who got hit by his sword technique got slash into two pieces as there are some who got slash in the neck and that causes them to lose their head, there are some who got slash in the stomach and that causes them to lose their lower half, and there are also some who got slash in the private part and that causes them to lose something precious. (A/N: You can imagine what precious thing that they lose)

Suou who is behind all of them is shocked when he seeing all of his followers split into two as the attack is going towards him too. Unfortunately, Suou instantly put a barrier around him when he orders his follower to attack Tetsuya, as he got a feeling that the boy in front is going to launch a monstrous attack when he saw Tetsuya let out his mana, and his feeling was right as the attack instantly kill all the mask men in front of him. When the attack hits Suou barrier, Tetsuya attack disappears slowly as it leaves a crack in Suou Barrier.

'Tchh... If only he die from that attack, I would get another free EXP. Oh well, at least I killed 14 of his follower.' think Tetsuya while looking at Suou.

-------------------------------

Shuri who saw this doesn't know what expression she makes right now as she is beyond shocked when she saw Tetsuya use the 'Muramasa Sword Art technique' when attacking the mask men.

'That technique... It is the same as Anna. Don't tell me that Tetsuya-Kun already mastered Anna's technique. No no no that is impossible since it so hard to master it even for Anna, but if Tetsuya-Kun already masters it then he is indeed more talented than Anna...' think Shuri while looking at Tetsuya with a complicated expression.

Akeno who saw Tetsuya attack is still blushing as she started to imagining Tetsuya as a prince charming who save her from all the villains.

Suddenly the katana weapon that Tetsuya hold in his hand started to crack a little as he already used his technique one time. He then uses his 'Weapon Appraisal' skill to check his weapon.

-------------------------------

[Himejima Clan Katana]

Durability: 62

-------------------------------

'Looks like I can only use it for 4 or 5 times more before it broke.' think Tetsuya while looking at his sword as he didn't want to use his personal weapon to fight all enemies since he didn't know what to explain to Shuri and Akeno about his personal weapon if they saw it.

"Well then old sh*t, I only need to hunt 23 more of your follower then after that kill you." Said Tetsuya with a smug face.

"Stop calling me Old sh*t you little brat!!!" Shout Suou while looking at Tetsuya with the gaze of hatred.

"Well that little brat that you hate will bestow you the name of Old sh*t the mightiest of all sh*t, so be thankful you Old sh*t." Said Tetsuya who still has a smug face on his face.

"You Brat!! hahaha fine have it your way you brat!!! because you're going to die here anyway." Said Suou who has veins in his head while having a killing intent toward Tetsuya.

"Bring it on you Old sh*t!! Well, why don't you call all of your followers so they can join the party." Said Tetsuya while trying to provoke Suou so he can finish all of his followers with 'Muramasa Sword Art Technique'.

"No need, since I need them to kill Shuri and that cursed child after I kill you." Said Suou while has an evil smile on his face while looking at Shuri and Akeno then look toward Tetsuya.

Suddenly all the blood inside of the dead body suddenly comes out and gathers in the palm of Suou.

"I didn't want to do this since it will decrease my life span but, since you are a threat to the Himejima clan in the future, I will have you die here right now." Said Suou who still focusing the amount of energy on his palm.

Tetsuya who feels the power that gathers around Suou arm feels dreadful as this is the first time he sees mana that is so dark yet chaotic at the same time.

All the blood that gathers around Suou palm slowly turning into a darker red flame that started to form the shape of a big bird that is so bright yet dark at the same time.

"Tetsuya-Kun... you should run now and take Akeno with you, that is not something you can handle!!" Shout Shuri while looking at Tetsuya with a panic expression because she knew the spell that Suou is going to use is one of the forbidden spells from the Himejima clan.

"Too late!!" Shout Suou while the big bird that just been created by dark red flame is flying toward Tetsuya.

Before the big bird comes near Tetsuya, Tetsuya uses his mana manipulation to form 2 barriers around him and also around both Akeno and Shuri. 2 months before Tetsuya also learn on how to create many things with his mana manipulation, and this cause him to learn spells such as barrier and many more.

The big dark red flame bird then crashes into Tetsuya barrier of mana.

"Don't worry Shuri-san, I can handle this." Said Tetsuya while looking at the behind of his back where there are Akeno and Shuri.

"But--" Before Shuri is about to say something, her hand is held by Akeno.

"Don't worry Mom, let's trust Tetsuya. Because he already promises me that he will be fine." Said Akeno while holding her mother's hand, but her hand is trembling since she didn't want to lose Tetsuya.

Shuri who notices her daughter's trembling hand can only stay put.

Shuri knows that Akeno also worried about Tetsuya since there is still a chance that she will lose Tetsuya, but she still believes in Tetsuya whether the believes are rather blindly trust at Tetsuya or she knows his power all along. And that makes Shuri decide to stay put and believe in Tetsuya.

'Tetsuya-Kun, you better come back safe or I don't know what to explain to your mother if something happens to you.' think Shuri while hoping that Tetsuya comes back safe and sound.

The big dark red flame bird then roars towards Tetsuya and crashes many times into Tetsuya barrier causing the barrier to slowly crack.

*sigh* 'Looks like I didn't have a choice anymore.' think Tetsuya while sighing.

Tetsuya then pierces the katana weapon on the shrine floor and starting to pull something in the air.

Tetsuya then pulls a short sword with a chain-link tassel in the air.

Shuri and Suou who see this are shocked at what just happened in front of them.

'That brat can use Space Magic !?' think Suou with widened eyes while looking at Tetsuya who is pulling a sword.

Shuri on the other hand is confused and shocked because she didn't expect Tetsuya to suddenly pull a weapon in the air. She knows that Tetsuya's mother Anna and Tetsuya's father Yukio can pull their weapon in the air because they store their weapon inside their personal Dimensional Gap that they use only to store weapons and other stuff.

The difference between the normal Dimensional Gap and the Dimensional gap that they created is the one that they created is seclude from the Dimensional Gap where Yukio created the Dimensional Gap by taking a part of the Dimensional Gap energy and created his own dimensional gap with his mana.

Unlike normal Dimensional Gap, this one can only be accessed by the one who created it, and also everything that entered it doesn't die or turn into nothingness since it was created by mana, unlike normal Dimensional Gap. In other words, is that they created magical storage that can store anything for themselves including living things.

Akeno who saw Tetsuya pulls a sword in the air is awed since she saw a new thing and expects this to be normal in the Supernatural community. But what she didn't realize is that there only a few people who possess the abilities to do this.

Unknown to them, Tetsuya just pulls his sword by opening his [ITEM] system, and not some kind of abilities that they imagined.

Tetsuya then put a stance while moving his right hand forward while holding a short sword with a chain-link tassel toward the floor.

"Rejoice Old sh*t, you are the first person to become the victim of this weapon." Said Tetsuya while looking at Suou with a serious expression.

Tetsuya then activates some kind of mechanism from the short sword and that causes it to unleash a bright red color light from the bottom of the sword with some wind pressure around the short sword.

"INCURSIO!!!" Shouted Tetsuya with his eyes full of determination to kill Suou for more EXP and also to protect Shuri and Akeno.

Suddenly a huge aura that slowly transforms into a beast appeared behind Tetsuya, causing Shuri, Akeno, and Suou to shocked once more.

'What kind of monstrous aura is that ?! I should ru... No, there is nothing that my forbidden spell can't defeat, why should I feel afraid.' think Suou who still thinks he can win, but there is still a slight fear in his body that causes him to tremble before the huge monstrous aura.

Shuri who saw the huge aura feel worried about Tetsuya safety since this is the first time she saw this kind of power, but soon calm down as she trusted Tetsuya to make his own decision.

As for Akeno, she is amazed by the huge powerful aura. But there is no fear in her feeling as she feels safe because she believed that the power that Tetsuya unleashed is to protect her mother and her.

The big aura started to enveloped Tetsuya body as it makes Tetsuya body surrounded by a red color aura. In a split of a second, there is a change in Tetsuya eyes as both of his eyes started to become red with a cross slit pupil at the center, but soon his eyes change into normal after his transformation completed.

Right now Tetsuya's body is now covered in armor from head to feet. Unlike Tatsumi before evolved and Bulat Incursio form, Tetsuya Incursio doesn't have a cape on it. And because Tetsuya's body is smaller than Bulat and Tatsumi, his armor suit is smaller because of his age in order to adjust to his body to suit his fighting style. Tetsuya helmet is the same as Tatsumi before evolved and Bulat Incursio form of helmet, but there is slight difference such as the horn of the helmet is longer but slightly shorter than Tatsumi evolved form, and has more tooth than before evolved but also less tooth than Tatsumi evolved form. His body armor and other part are still the same as Tatsumi before evolved and Bulat Incursio form but Tetsuya has more protection armor around his body especially his arm and leg.

Tetsuya then pulls the katana weapon that he pierces into the floor.

"Let's begin the massacre shall we?" Said Tetsuya while looking at both the big dark red flame bird and Suou.
