Goteitaishi is a Shinigami and is a member of the Eleventh Division. Goteitaishi is quite brutish and intimidating on many occasions, however he has also been shown to be quite cowardly when around people he is scared of. He also has the common view of many in his Division, which is that weak people are useless and only strong people should be in his Division by stating to Seizo Harugasaki that it is sad that people who can not fight are allowed to be a part of his Division. He also at times acts superior to other people, who are not as strong as him, demanding them to do stuff for him.
