tajikarao (housamo)

"A Transient from the other world of Takamagahara. He is a student at the Police Academy located in Kabukicho. While he isn't particularly skilled at thinking deeply, he loves enhancing his body and is an active member of the weightlifting club. His secret hobby is to show off his sculpted body, so if there is an event where he can dress scantily, he will enthusiastically participate. His very arms, both as strong and hard as boulders, are his Sacred Artifacts. In order to seal their power, he habitually wraps them with sacred rope. However, those ropes frequently come undone, or are soon cast off."

Often wearing a nejiri_hachimaki with fundoshi.
