Ren

Ren is one of the protagonists in Caseyshow.

One could say he is in love with himself.

He can be extremely vain and narcissistic.

People often think of him as a complete dumbass.

He's said to care about himself, and only himself.

He seems to keep maintaining his appearance as his top priority (and if he has to stop, even if only for a moment, he still seems To Still Love Himself).
