Based off multiple bands I listen to! Saiki is the main singer, he's mainly based of MY FIRST STORY's main singer, Hiroki Moriuchi. Hiro Mitsua is one of the guitarists, along with Saiki who plays tool. Hiro is just kinda the embodiment of the awesomeness that comes from the genre in my opinion, great tattoos, great style, and great music. Katsuki sounds just like he sounds, a sorta cat dude pianist. Really awesome, kinda goofy dude (no wonder, he wears cat ears lol). #jrock #jpop #anime #band
