Demon Know As Takeda Shingen

Ikishima Ren is a highschool student who lives a peaceful life.

People that lives in his town knows that he is the kid who born without CHIKARA. So they always treat him like a pity child. 

However Ren doesn't seems to care about it. he always been alone. Ren lost his father in an accident. and his mother works in abroad so he lived his life alone.

Some of the bandits who lived in his town noticed it and planned to rob him while he walks home. 

Oneday after the school's over he walked home alone. on his way to the home the bandits attacked him and tried to grab his wallet.

Ren pushes one of the bandit and starts running into the direction where the more people will be but bandits used their Chikara to stop him.

One of the bandit possessed a chikara know as Shockwave. He uses it in Ren. it hits ren directly and makes him unconsciously fly threw the air.

Ren falls into a river. since he doesn't have a Chikara. bandit thought he'll die. and walked away from there.

But he didn't die as they thought. he is just unconscious. when he wakes up it's already midnight. it's Pitch black out there.

 something starts to glow in the dark far away from there. after seeing it ren starts to walk in that direction.

that bright light starts to get visible to his eyes. it's a monument. when he realize that he is standing in a abandoned graveyard. he starts to tremble in fear.

He slowly starts walking near the monument. and reads the name that wrote in it.

"Takeda Shingen" 

After reading that name loud. atmosphere in that place starts to change. cold wind and thicker mist starts to get even thicker.

From that mist an armored man appeared. The man who died 448 years ago. "Tiger Of Kai Takeda Shingen"

Also Know As The Devil Samurai.

He starts to speak.

"Who are you brat! why did you wake me from my sleep. you have any death wish huh"

Ren was frightened. he couldn't talk.

"Wait! why don't i sense any Chikara inside you?"

Ren starts talking

"I... I didn't born with one!"

"Huh You didn't born with one?"

After a few seconds of silence Takeda Shingen starts laughing.

"Why are you laughing?"

"You said you didn't born without one. it reminds me of my older self. Hahaha"

"Wait. you also didn't born without Chikara? but you are the legendary samurai once lived. who slayed Thousands  of People. how's that possible without chikara?"

"Yeah It's tough to be without one when people around you have more powerful chikara. however Power is not the only thing that matters to be Strong. what more important is a pure heart and a guts to standup in front of any people. people who have more power than you"

"It's nonsense. even you have a pure heart and stand in front of powerful people. they'll kill you in an instant"

"Haha... I didn't say that's the only thing matters the most. i trained hard. my parents where killed in war. i wanted to be strong. so i trained hard. harder than anyone. some wars are tough sometimes i beaten-up so badly."

"I figured that much"

"Hey... since you don't have any chikara how about i give you my Katana(Katana Is A Specific Type Of Japanese Sword). since i'm already dead i don't need it anyways. how about that?"

"Even you gave me your Katana to me. I still don't have any chikara. yeah you had the skill to slay thousand people with that Katana. but it's not like in your times. now the world has changed so much. people became more powerful than your times. it's pointless. they also have schools that they train Kids with Chikara. i don't stand a chance."

"People don't know how i died..."

"Wait it's a mystery... How did a strongest guy like you died in the first place?"

"One day after ending the war i visited a nearby shrine. there was a red power source that has been sealed away into a lantern. when i touched it. i overwhelmed with tremendous amount of power. some of the most powerful people who lived in that time noticed it so they came after me. i don't know what to do. After all these war i was severely injured. i know that i won't last too long so i passed that power in the last minute."

"After That. you were powerless and weak again? so they killed you?"

"Yes. after killing me they thought they'll consume that power inside my body. since i passed that power into my sword they didn't find it. i became the Wielder of that power. since then i'm the only one who can use That sword. who ever touches it became sick and died."

"So that's why rumors says that you still live threw the sword and it's cursed."

"Yes. Until i passed down the power inside the sword. i can't rest peacefully. that's why im still here as a spirit. that's why i'm saying it. i'll pass my power into you so you can wield my Katana to it's fullest."

"Even so you give me that Katana with that power. how am i going to wield it? i don't even know how to wield a Katana."

"haha it's up to you. you have to figure it out. but we have to make a deal before that."

"Deal? what kind of a deal?"

"You have to wield my katana to protect those people in need. and you have to Aim for the biggest rank in this nation called Chikara Emperor"

"You are kidding me right. Chikara Emperor means most powerful chikara user who can rule the nation. how am i suppose to get there."

"Like i said it's up to you. you have to train hard for it. but i know you can make it. Because im also grown without a chikara. so i can understand you more than anyone. you agree to the deal?"

After few minutes of deep thinking Ren agreed the deal. and That's how Ren made a deal with the devil who know as "Devil Samurai"

After it. Takeda Shingen disappeared. from this moment on Ren's life's going to become more tougher. what's Ren gonna do next...
