long ago, you swore allegiance to Katahara Metsudo, taking care of him of anything and being one of the chosen ones to be Metsudo's Fang... But you'd be defeated by Kanoh Agatha, the current Fang of Metsudo... And you'd come to hate her...

but after a while, you would become friends with Tamaki Minoru, a muscular girl who always wore a mask to cover her mouth, they always talked and chatted, when Katahara started the Kengan tournament, you and Tamaki would be walking through the halls of the coliseum until Tamaki would tell you something

Tamaki: Hey... How about we train, I always wanted to know how strong you are... she looks at you seriously
