Kaiser is a tall older man with pale green hair combed back into several curls. The sections above his temples are flared up and shaped like wings. He also has a pale green handlebar moustache.
Kaiser is shown to be humble. According to Fuegoleon Vermillion, Kaiser took on the role of Magic Knight Captain for the sake of his fellow brigade members, even though he disliked standing out.
After Gueldre Poizot's removal from his position, Kaiser takes over as captain of the Purple Orca squad and, at Julius Novachrono's request, attends the annual Star Awards Festival. Kaiser is not surprised when his squad ranks 8th.
After the ceremony, Yami Sukehiro greets the other captains and brags about his squad's placement over theirs, and Kaiser reminds Yami that he should not miss meetings. The other captains then leave, refusing to celebrate with Yami.
Weeks later, after Patolli sets the last magic stone in the sephirot, Kaiser is possessed by an elf spirit. Later that night, all the remaining elves are exorcised after William Vangeance and Licht combine their magic to connect the elves to a giant tree through which Asta sends Anti Magic.
