Great King and Sword Emperor's Successor?

Reina and Esri went to Shinichi worriedly as they saw Shinichi with a heartache expression.

"Shin-chan it's fine, my cousin will heal Reiji without a doubt she is special and a powerful healer." Esri comforted Shinichi

Shinichi just nodded and started to speak "Reina do you remember the first time we met and saved you?"

"Of course, it was our fated meeting" Reina replied sweetly

Shinichi suddenly hugged Reina as he saw her heartwarming smile before he continued "That is also the first time in my life that I felt pity for someone else's tragic history and wanted to protect you because you don't deserve it.

"Next is you Esri," Shinichi said, Esri only looked at Shinichi listening carefully to what he was about to say.

"It was my first time to encounter a woman like you, that can make my day bright every day. Every time I teach you a sword technique and when I saw your cheerful smiles whenever you succeed, it makes my heart calm and wanted to dote on you." Shinichi said as he patted her head

"Next is Emily-san it was also my first time experiencing a mother love even a little. And even entrusting me her precious daughter Elly. And now these mages wanting to sacrifice themselves for me, even though all I did was to command them and lastly…" Shinichi suddenly stopped and looked at Reiji's peacefully sleeping

"Reiji, it was also my first time in my life to feel how to have a life and death brother who is willing to help you and protect your love once in exchange for their lives.

"At first all I wanted was freedom, a freedom to enjoy my life without caring about others. But after meeting you all, I felt that my life is only not for myself anymore.

"My life is also for my love once, for the both of you Reina and Esri, for the people who want to sacrifice themselves even knowing they will die in the process, for my brother who bleeds because of my carelessness and my naivety. I forgot that I was facing a wicked Demon.

"I was only enjoying myself to the fullest to be able to fight a stronger opponent than me. But because of that, it makes the two of your lives in danger and makes my brother face a death threat and bleed." Shinichi said as he blames his naïve self.

"Shin-kun, you don't need to blame yourself; this was a battlefield there are always mishaps happening, also it was your first time facing a demon." Reina comforted Shinichi

Shinichi shook his head and said "No it was my fault. I was fooling around in the life and death battle that in a little mistake is the death of me or even some of you. So…" Shinichi suddenly stop talking and look at where Mammon was sent flying.

"I will not hold back anymore; I will defeat that demon now and burn him alive until he begs for forgiveness," Shinichi said with a terrifying expression on his face and his eyes starting to ignite with flames.

Both Reina and Esri saw Shinichi's terrifying expression, it was their first-time seeing Shinichi this angry. The mages who went to Shinichi and wanted to talk suddenly took a step back and closed their mouth.

The handsome young man who they adore as a commander that been commanding them calmly was now has a terrifying angered expression. As they all looked terrified by Shinichi, an explosion resounded 300 meters away from where Mammon was buried.

Bang!

Mammon shot out to the sky and looked at Shinichi "DAMN YOU! HUMAN! That irritating flame! I will…" Mammon shouted angrily but before he could complete his sentence a calm voice was heard by him

"Hey! You!" Shinichi said calmly

Mammon looked at Shinichi and caught a glance at Reiji that he thought he was dead "Hmm? Oh! Hahaha is that your friend I just killed? What does it feel like? Huh? HOW DOES IT FEEL? HAHAHA"

Shinichi didn't answer him only looking at Mammon and started to speak again "You make my lovers feel death, you make my friend cry, you make my brother bleed, you make my comrades terrified. It was all because of you damn Demon!" Shinichi said in a calm voice but his face was contrary to his voice.

"Are you angry? I like the look on your face right now. HAHAHA!" Mammon asked instead in a mocking tone as he laugh like a madman

"Our duel will start now! You are insanely strong, but I will surpass you now so that I can protect those people who I treasured" Shinichi declared as he started to raise his hand slowly

"Hah! Don't make me laugh! They will only be a hindrance to your growth and a burden to you. But I like it because, with this, you will feel even more despair as I killed them one by one HAHAHA"

Shinichi didn't speak this time as he continue to raise his hand and grab the hilt of his sword. The moment Shinichi grab the hilt, the Air around him suddenly changed.

The mage all felt that a thousand sword was pointed at their back of course it was the same to Mammon he also felt it. Fiona who asked the question if Shinichi's sword was only for decoration felt shocked. 'So, Esri-chan was telling the truth that he is a strong swordsman' that is what is inside Fiona's mind.

[Master, I won't recommend using that technique with Master's current strength.]

Shinichi didn't answer and Hestia continued

[The combination of the sword qi and magic element is a huge strain in Master's body, even the sword emperor abandoned his magic elements to achieve the highest peak that it could reach]

"…Its fine Hestia, if I don't bet my own life. While my lovers, brother, and comrades are all risking their life. I won't be able to forgive myself" Shinichi said with resolve.

[…I understand Master, if you wanted to do it, I will do my best to at least lessened the burden]

"Thank you, Hestia"

Shinichi suddenly started to emit a tremendous amount of sword qi as he slowly unsheathing his sword, it was different from his always quick draw sword technique. Esri was gasping in excitement and expectation as she watched intently to Shinichi's movement because this is the first time Shinichi ever unsheathed his sword fully.

After a while, Shinichi's sword was fully unsheathed now and a small mountain in the back of Mammon was cut in half. All mages, Lisa, Fiona, Esri even Reina were all dumbfounded beyond disbelief. How can he cut the mountain in half just by unsheathing it slowly? Mammon also was dumbfounded he suddenly felt a death threat coming from Shinichi's sword.

"That sword! Don't tell me you are also one of the descendants of the Sword Emperor!" Mammon was felt terrified this time because, in the history of ancient times, the Sword Emperor was also called the natural Enemy of the Demons as he also has a title of a Demon Slayer.

Shinichi's sword was color black with ancient writing on the left and right side of the groove, the hilt suddenly changes from a normal hilt to a black dragon head shape hilt when fully unsheathed. The word written on the left side was, Sword Emperor: Oda Ken, and on the right side was Successor: Oda Shinichi.

Shinichi doesn't know it because he doesn't know how to read an ancient text and his master didn't tell anything about it. His master only told him that this is the proof of him receiving his legacy.

Mammon felt that this young man is not a simple warrior, he felt that something is going to happen in the future as this youth leading the human races even the other races as he also saw the little Phoenix on the shoulder of Lisa "You don't only have the power of one of the Great Kings, but you also have the power of the Sword Emperor! this is impossible!"

He can't believe that a human brat can wield the two power that is said to be an impossible feat. Sword qi and Magic Element is not compatible with each other and it is said that if they tried to use both powers a body of a mortal won't be able to withstand the burden of these two different power and their body will explode by the sword qi energy and magic energy.

He doesn't know that Shinichi's body was already divine in an infant state. (A/N: Go to chapter: 13 to know the small detail of Shinichi's body)

The mages heard the loud voice of Mammon, their jaw dropped when they heard the word 'sword emperor' because he was a famous existence in the lower realm, they don't know the Great Kings but they all felt that it was also another Legendary existence in the higher realm if this powerful demon knows about it and according to his actions earlier, it means that Mammon experience defeat against these so-called Great Kings.

Esri on the other hand was so ecstatic when she heard Mammon, 'So, my man is really the sword emperor's successor, I was so happy! I can't believe that the man of my dreams is my future husband'

As a Sword Emperor fanatic, Esri is the only one who has a different expression than all of the people who heard Mammon, all of them were shocked only her was in a state of happiness and ecstasy. Reina, on the other hand, doesn't care who Shinichi was, even he was a child of a Demon or a Heavenly emperor it won't change the fact that he is the one who save her from the loneliness and tragedy of her past and his woman, who will support him wholeheartedly.

Shinichi on the other hand suddenly remembered his Master's words as he looked at the majestic fully unsheathed black sword.

A kind old man's voice suddenly echoed inside Shinichi's mind "Shin, don't ever fully unsheathe this sword in front of many people to see. But if your life Is in danger, or you wanted to save your friends, love once and you felt the need to fully unsheathed it don't hesitate to use it. Your life and your love once are more precious more than anything else."

'Master I will use this sword you entrusted me to save my lovers, brother, and comrades.' Shinichi murmured and he raised his sword above his head.
