Alma

Alma is serious, brave, yet somewhat reckless. After being awakened by Hikaru, he tries to combine (derize) with him, but fails and ends up getting stuck to the hoodie Hikaru was wearing instead. He doesn't have any memories prior to being sealed away. He is called "Trigger Arm" by the Kagami Group. Arma likes Otaku activities like reading manga, and games, and watching anime and movies. He dislikes getting lemon juice in his eyes. (Source: Official Site)
