Torahiko Kusakabe

ArS's leader and an artist through and through, Torahiko is a freelancer who paints unique and extremely invigorating pictures. To him, art is more important than anything; his eccentric personality puts art as a priority, and he'll take off even before a live.

In that way, he appears to be renowned artist, but on top of that, he's been working as a children's book author from a young age. The name he used during that time was, "Tiger Kids." I♥B's Lucas is a fan of his.
