Takiya Genji is the main protagonist of the Crows Zero film
One day, he and Tokio went to climbed an electric tower and this is where Genji would accidentally cut himself on his left eyebrow when he saved Tokio from falling .
Genji enters Suzuran All-Boys High School as a transferred senior with the goal of conquering it.
His father, Hideo made a deal with him, stating that if Genji succeeds where he failed, in uniting the infamous delinquent school Suzuran, then he will allow his son to succeed him as the boss of his Yakuza organization.
He eventually forms his own faction, the GPS (Genji's Perfect Succession) and goes to war with the Serizawa Army's Serizawa Tamao, who was the closest to ruling Suzuran before Genji showed up and opposed his dominance over the school.
With the help of Hideto Bandou, the GPS was victorious in their final battle with Serizawa's Army despite being outnumbered. After defeating Serizawa himself, Genji then turned his focus towards beating the second year Rindaman who was said to be undefeated at Suzuran High.
Genji unwittingly broke the non-aggression pact between Suzuran and Housen when he interfered with the Housen Killer Corp's revenge on Kawaishi Noboru, who was responsible for Makio Bitou's death two years earlier.
This caused Housen's Head Narumi Taiga to declare war on Suzuran.
He defeats Taiga in a one on one on the top of Housen Academy's rooftop and was recognized as the "Captain" of Suzuran's forces during their assault on Housen Academy.
