Kenichiro's Revenge and on the bottom, his techniques

Kenichiro Yamada.

A man desiring to avenge his father. 

Kenichiro was taught Yamada-ryuu Martial Arts, which has elements of Karate, Kenpo, and Judo.

At 13, his father told him the tales of Jingami, a fabled demon who lives for the thrill of death matches, and suspects that he has been targeted. As a dark and windy night passed, a demon wearing gray Super Saiyan-like hair, gray gi-pants, and red glowing eyes was destroying the Yamada family home. Jingami had arrived. To protect his son, his father tried to fight him off, only for each of his attacks to prove useless as he met his end by the hand of the demon. 

Kenichiro watched in sorrow and anger as he left, swearing to end Jingami's terror and avenge his father.

Now 21 years old, and traveling throughout the world without a home, all he could think about was those glowing eyes and chilling voice... and that final blow he struck upon his father. 

Later, in an abandoned temple, Kenichiro stood before Jingami, full of determination and anger, his fists violently clenched. Jingami looked on with an evil smirk, "So, another victim has approached me to fall before my fist."

Kenichiro's fist was raised at him, shaking it violently "Jingami... I'm here to destroy you for what you did to my father!"

Jingami hysterically laughed and stood in a stance with bent knees two shoulder widths apart, his fist to his hip and his other hand pointed forward. "You really believe you're capable of such a feat? Prove it, boy."

During the fight, Jingami dodges each and every one of his attacks, countering with a fatal palm strike, sending him sprawling through the floor. Crossing his arms, the demon laughed out hysterically, "Worthless boy. Your father would be so disappointed." 

Kenichiro looked on with anger as he slowly stood up, remembering his father's teachings as he tried to find a way to defeat him. 

"So you finally decided to fight?" Jingami approached him, launching a side kick, but Kenichiro grabbed it and shoved his head at his ribcage, leaving Jingami to stagger back  before attempting to land a vicious uppercut, only for Kenichiro to sidestep and strike him with a Karate punch. 

Incensed at how Kenichiro was able to somehow put in effort, Jingami approached with ultimate speed which made it quite impossible for Kenichiro to dodge as he was grabbed by the neck, thrown in the air, and was spin kicked away like a baseball, sending him back onto the wooden floor. As Jingami leapt off the ground and charged straight at him with a diving palm strike, and sensing an opening, Kenichiro landed a powerful uppercut at his ribcage, finally defeating the demon.

"Consider this revenge...for my father!" 

Kenichiro approaches the cemetery where his father was buried, having finally accomplished his goal. "Your death has been avenged, Father, and now you can rest peacefully. As for myself, I have a lot to learn."
