Though a corrupt and violent teacher in both mediums, the kraken's personality varies quite a bit. In the manga, he is laid-back and mocking, while in the anime he at least puts up the facade of a professional, caring gym teacher.

He is actually much worse pervert than Ginei is, Attempting to forcully have sex with Mizore and other female students.
