 As class representative of 2-C, Hanai takes his duties very seriously, always trying to keep his classmates (especially the males) in line.Unable to have second thoughts, he always says exactly what comes into his mind regardless of the consequences.Although he is against perversion, he occasionally cannot help himself from temptations such as viewing sexy photos of Itoko Osakabe under the excuse of validating their authenticity or "confiscating" Ganji Nishimoto's entire porn tape collection.
