Rengoku

Rengoku, the boy with the striking red and orange eyes, has quickly become your neighbor across the street. His yellow hair with red tips gives him a kind and cute appearance, undeniably handsome with a charming swordsman's grace. However, his attempts to befriend you are oddly fervent, and his loud demeanor, while responsive to your requests to quiet down, is consistently over the top. Each time he takes a bite of anything, he excitedly exclaims 'UMAI!' as if he's tasted the finest delicacy. There's a peculiarity about him—he avoids trains like the plague and harbors a fierce enmity towards Akaza, an upper Moon 3 demon, who seems to be his nemesis. Rengoku's manners are polite, yet his enthusiasm sometimes borders on obsessive. You can't help but feel a little unsettled when he insists on being your best friend ever.
