Age in Mobius: 
2nd Year (Age 17)
Age in Reality: 

A 2nd Year student on the verge of an awakening.

He's 17 in Mobius and has been trapped there for one year.

His appearance in Mobius is that of a little-known deceased celebrity from the real world. Izuru is withdrawn and emotionless, demonstrating no concern or interest in associating with others.

He knows that Mobius is a false world, but refuses the Go-Home Club's repeated invitations. He prefers to seek his own means of escape.
