Height 176 cm Position Seat XIII A lone wolf lacking in sociality. He may appear rather mature for his age, but is fast to lose his cool when complimented over his effeminate features - a trait that became somewhat of a complex for him. While normally agreeable with others, he draws a clear line between himself and the rest of his schoolmates, with the exception of a few close friends. Unfortunately, about two months prior, a brutal fight inexplicably broke out between him and Shirou Yusa - his best friend - that left both of them hospitalized, placing Ren's already fickle reputation at school in complete jeopardy.
