7 Sensei!

*SLASH!*

A sword light flashed as a head flew out and blood gushed forth from a neck. Scar-man's face rolled on the floor after falling down. The look on its face was still of a cruel smile and a laughing expression.

Kurama and Rias, after seeing the scar-man dead, the crimson glow on Kurama's chest and Rias' head immediately died down. Somebody just cockbloc- err... powerblocked Kurama and Rias.

Kurama was still lying on the ground and was stained by the blood that was splurted out from the neck. He was stunned by the sight of blood fountaining under the moonlight of the nightsky.

"Beautiful!" Kurama muttered in a dazed state.

Rias immediately lost consciousness after scar-man's body went limp. She was suffocated as the scar-man was choking her by the neck.

Footsteps was then heard walking towards Rias. Kurama woke up in his dazed state and looked towards the sound. He wanted to go and tend to Rias but his body won't move no matter how hard he tried. He just stared at the man who was walking towards his twin sister.

He saw a 20-year old looking man with long white hair that reached his shoulder, he was wearing a white polo, pants with split ends, brown slippers and a green coat hanging on his shoulders. He was holding a katana with his right hand and the sheath on his left. He was also chewing a straw on his mouth.

He had an irritated expression on his face as he looked at Kurama and Rias lying in front of him. He then walked towards the scar-man's head and put it in a sack which God knows where he got it from. Amazingly, the sack vanished without a trace after he put the head inside wich greatly stunned Kurama.

He then turned back and looked at the twins. He furrowed his brows after seeing the state they were in. He looked at Kurama and said, "What are kids doing here?"

He seemed to be asking himself the question then shook his head. He looked at Kurama and asked, "Kid, what's your name and what are you doing here?"

Kurama tried standing up but only managed to sit down. He stared at the man in front of him and said, "My name is Kurama, Kurama Gremory. Thank you for saving us." Kurama bowed his head slightly as a sign of gratitude.

"Gremory huh... so you're that man's little brother and that little girl should be your twin sister." Said the man as nodded at himself.

"That man? Wait, you know us?" Asked Kurama as he was puzzled by the man in front of him.

He then nodded and said, "Name's Ito, Ito Mishamon. Let me get you kids home as I know where you guys live."

Kurama nodded and went to Rias as he can finally stand back up. He carried her on his back as Ito just watched him with a look of 'I'm not helping you'.

The both of them were walking in the forest with Ito leading and Kurama following. Kurama's mind was wandering when he suddenly remembered that sword light. He looked at Ito's back and called out.

"Ito-san!"

"Hmm?"

"Can you teach me that sword move you made earlier?"

"No."

Kurama was surprised at the immediate refusal, but that didn't put him down so he asked why.

Ito just continued walking casually as he said, "Why would I teach you? What's in it for me?"

Kurama smiled and said, "We have lots of money."

"I don't need money." Ito casually replied while waving his hand as if buzzing a fly off.

Kurama was once again surprised at the immediate refusal. He then asked, "Then what do you want, Ito-san?"

"We're here." Ito didn't answer his question as they arrived at the Gremory residence.

The door to the house opened and Venelana could be seen running towards Kurama with a worried expression. Soon, Zeoticus came out along with Sirzechs who immediately went back home after hearing that Rias disappeared along with Kurama who followed after her.

Venelana who saw her children in such a ragged state had tears in her eyes as she then glared at her husband with hatred. She then began tending to the twins while asking where they were hurt.

While Venelana was busy with the children, Sirzechs walked towards Ito and said with a smile, "Ito, long time no see."

"Indeed, long time no see Sirzechs."

"Can you tell us what happened?"

"Well, I don't really know much. I was on a request about killing a certain A-rank stray devil, and coincidentally, the stray devil that was on my kill list was on the verge of killing those two. So, I just took the chance to easily kill him while indirectly saving them both." Ito said with a casual voice, not minding whether it terrified them or not.

The twins' parents and Sirzechs were stunned as they didn't expect that they were so close to losing both Kurama and Rias.

Sirzechs took a deep breath to calm himself and bowed deeply to Ito while saying thanks. "Thank you Ito. If you were not there, we could have lost our twins. If you would like, stay for a few days or weeks in the residence, Ito."

Ito just nodded at the thanks. He didn't really care and said "Don't worry about it, and yes I'll be staying at your house for a few days, that's why I'm here anyway."

After saying that, Ito directly went inside as if it was his own house. Venelana was holding Rias and said in a cold tone "Zeoticus lets go inside."

Zeoticus had cold sweat running down his back as he nodded with a fearful expression. Venelana turned to Kurama and said, "Kurama, come, let's go inside."

"I need to talk to nii-sama first Mama." said Kurama as walked towards his brother. Venelana nodded showing her consent.

"Nii-sama, do you know who Ito-san is?"

"Ito? Yes, he is the strongest swordsman alive in this world right now. He is also known as the Cursed Swordsman..." Sirzechs replied.

Kurama's eyes gleamed in admiration after hearing that Ito was the world's strongest swordsman. Sirzechs then started telling Ito's story to Kurama.

Ito Mishamon, His story begins when Japan was being founded. Him and his brothers, Bato Mishamon worked for the Emperor as his best swordsman because they possessed the sacred gear [Sword Birth] and [Blade Blacksmith]. They helped the emperor slay thousands of devils and monsters for the sake of the empire. During the war the Emperor was saved by Ito and in his gratitude gave Ito his first daughter Akiko to marry. One night he went away on a mission in the Underworld and never came back which made everyone believe him to be dead.

When he came back almost five years later he had learned that his brother Bato had relations with Akiko and she had bore his kids. In anger he tried to get his brother to fight but he refused but Ito killed him anyway and then killed Akiko and their kids in rage. Feeling remorse and ashamed for what he did he summoned a devil to help bring them back to life. The devil agreed but then a curse was placed on Ito making it so he forever walked the Earth alone in hope of the 'Ultimate Swordsman' to defeat him.

What he didn't realize was that he wasn't talking to a ordinary devil but the original Lucifer himself who put a curse on him that turned Ito into a phantom which made it so he was unable to take his own life or intentionally have someone kill him. He then walked the Earth looking for a better swordsman that could beat him but after almost 3,000 years of looking he never found one.

After hearing Ito's story, Kurama was sympathetic but had a look of admiration on his face. He knew Ito was strong but didn't think the he would be that strong.

Kurama soon bid farewell to Sirzechs as he went inside the house. He directly went to his room and saw Rias already sleeping. He follwed after and slept beside her.

The next day, both Rias and Kurama woke up. When Rias woke up, she was in a daze as she remembered what happened last night before she passed out. Rias then began asking Kurama what happened and was told that they were saved by Ito.

Rias then told Kurama with a determined expression on her face that she would get stronger to never allow that to happen again. Kurama replied by saying that he also wanted to grow stronger, strong enough to protect everyone he loves.

Rias then went to her mother to learn about her powers more. While Kurama went to find Ito.

He soon found Ito talking with Sirzechs. Kurama directly went towards him and bowed while saying, "Ito-san, please teach me swordsmanship. Please accept me as your student."

"No." Ito said while having an unfazed expression.

Kurama didn't stand up from his bow as he was no longer surprised about the immediate refusal.

"Please"

"No."

"What do I need to do to make me your student?"

"Nothing."

"Please!"

Kurama bowed while looking at Ito with a determined expression on his face.

Sigh~ Looking at Kurama's expression, Ito knew that this would be hard.

"Kid, what do I need a student for? I'm busy looking for the 'Ultimate Swordsman' and you want me to take you as my student? I literally don't have the time." Ito said as he tried to persuade Kurama to give up.

Kurama thought for a while and said, "But, how can you find the 'Ultimate Swordsman' when you are literally the Ultimate Swordsman himself?"

Ito was dumbstruck as well as Sirzechs. They didn't think of that at all. Ito looked at Kurama and was about to speak but Kurama beat him to it.

"So why don't you make the Ultimate Swordsman yourself. No, make me the Ultimate Swordsman. No need to stress yourself looking for something that doesn't exist."

Ito Mishamon was silent for a while before breaking out into a grin then laughed so hard that tears were starting to form on his eyes.

"HAHAHAHAHA! Sirzechs! I like this little brother of yours!"

Sirzechs just smiled wryly looking at ito. He then looked at Kurama with praise.

Ito turned to Kurama and said while grinning, "You're very clever even for kids your age brat! Fine! I'll make you my student. I'm gonna make you the Ultimate Swordsman just like you said. Don't go running to your parents with tears and snot in your face because, I'll make your life a living hell!"

Kurama got scared for a second there but then change his expression to a resolute and determined one.

"Yes, Master!"

Ito nodded in praise at Kurama's resoluteness. He then told Kurama to prepare for the training tomorrow after school.

Ito then stood up and went to the door as he opened it. Before stepping out, he said "Also, don't call me master. Call me sensei."

"Yes, sensei!" Kurama then broke out in a grin after Ito went out. He was happy that he made him his teacher. Kurama was excited for the future.
