Ren is an extremely arrogant and egotistical young man, calling himself "the world's strongest genius", and directly referring to Producer as his servant. His physical abilities are very high and he exceeds at dancing, being able to perform difficult choreography with ease. His innate talent causes him to be very lax and prone to skipping out on lessons, but when appealing to his ego, he is easily motivated. He also seems to be somewhat shy when it comes to dealing with girls and romance scenes.
