Its time

Skill(or transformation):Super Saiyan (The Legend)
How well do you know the source material? Yes
Reasoning: Over the wipe, Zane has become increasingly more stressed, put into more difficult and tense situations that drove him through everything from being lightly tortured, to managing Biology mostly on his own, to having to keep a constant eye on many of his troublemaking friends throughout the year and even being forced to turn against some of them recently. It reached a peak in the recent weeks, with the death of someone he only recently had come to know as a friend, and some of his very own friends turning against him to defend the monster responsible. Driven by all of that pent up frustration and anger, as well as the severity of the current situation leaving him about to lose everything he worked for, fail the ambition he set out for at the school, and lose any chance of fixing and repairing everything as he set out to do when the second quarter began. Its a fight not just for his own well being. but the preservation of his beliefs and the ability to stop anything horrible like that from happening to anyone else by stomping out any opposition that would be in his way. Fueled even further by the pride and rage of his inner-demon and how savagely he was just defeated twice in a row, I feel reaching a breaking point and pushing even further beyond would be applicable.
What is the moment: After spending the entirety of the other day practicing for the battle with Fuya against opponents like Jack and later Sachiko, as well as putting everything he had into pushing himself beyond his normal limit, it eventually came down to the battle itself. After being defeated in the first round using his final trump card, he was pushed to the edge of what power he had. Refusing to give in, despite the lesser consequences of what the duel started as, a second battle ensued with much graver stakes, some that threaten to ruin the very foundation of everything he worked for throughout the year and had continued to strive for even now, despite the worsening circumstances of the school. Now utterly crushed using the maximum his power allowed, even once again tapping into the Bijuu's strength, he stands to lose everything while simultaneously being forced to betray some of the few friends he had and fail to avenge the death of the white rider he had come to respect for their just intentions. This being further fueled by the insults and self-doubt brought about by the crowd around him as he rests in the dirt.
