Known by the nickname "Eyebrowless Rei." Features: A mouth curved into a 'he' shape (inverted V), a strange and unique face, flicked-out hair (moderately long). When he stays quiet, he actually looks quite dignified. He's a healing type who appeals to a specific niche. Personality: Believes that "expressing yourself honestly is the most important thing." He pursues being a "pervert" (eccentric) to be the seasoning of the world rather than just a cog in the machine. He has a bright, positive personality and is a beloved character who makes no enemies. Surprisingly, he can be quite gentlemanly and charming. Special Skills: Expert at superhuman "eccentric movements." He can perform "Chibi-fication," shrinking his body instantly to about knee-height when excited or shocked (all Kimengumi members can do this). He is known for bizarre behavior, flexibility like a boneless human, strange movements that ignore joints, and moving in impossible postures. Family: His family runs a toy shop called "Ichido Toys." His father, Takuseki (very cheerful and an eccentric like Rei), his younger sister, Kiri, and his dog, Lassie (who takes after his owner). His mother has passed away.
