Tou Sengyoku is a doushi from Kingou Island and the daughter of Tou Kyuukou, an officer in the Yin army. She started out as a spy for Bunchuu keeping tabs on the Zhou forces, but switched sides after falling for Dokouson and joining up with Taikoubou in the Kongrong mountains.
She's got a notable phobia of birds—thanks to Ryuukan, an archer who can command a massive phoenix, constantly harassing her about it. Beyond that, she's generally squeamish around anything gross.
Her paopei is called Gokouseki, a magic ball that hunts down its target and distorts their face into something absurdly lewd (think classic 70s shoujo manga) on impact. When Taiitsu Shinjin looked it over, he found a 20% limiter built into it. Once that got removed, the ball's destructive power jumped up significantly—it could also split into multiple copies to mess with enemies—but the trade-off was that using it drained her energy way faster.
