Izuru

Izu has a host kind of personality, all thanks to Hiro's influence, overly friendly to basically anyone tho it's only a front. Izu's pretty much pessimistic to the world, often getting irritated over the smallest things people do. You would rarely catch him without a smile plastered on his face but he does have times where his true face shows when caught off guard(only Pochi, Chihiro, and his mom can do this). But meeting Pochi and turning Pochi into his current production project, Izu starts to become the person he faked.
