Key: Alt F4 The Oblivious Troll
Character: Raizen Arashi
Skill(or transformation): Next tier of Self Enhancement. (Abilities?)
How well do you know the source material?(obviously not relevant if it's a transformation):
Reasoning:  Raizen had found himself onceagain, trampled by foes whom completely outclassed his fighting style. The training he had been recieving from Brina hadn't been enough for the massive Fighting Spirit of Chikara nor the Blade word of the Rider. Both of them easily flattening him one after the other. He hadnt even managed to land a blow on either of them before taking his untimely losses. Leaving him flat on his back, gasping for air.

His own modifications having let him down? Perhaps it was time he advanced them to a new level. He had been too complacent with them in recent times. It was time for an upgrade.
What is the moment:N/A
