The Imprisoned Demon Sergeant who Died for his Country

The Imprsoned Demon Seargent who Died for his Country
One of the spirits that Yayoi had raised.

Synopsis
After fighting for Japan in the war he returned and eventually died of old age, however instead of passing on he instead looked how he was in his prime, and was surrounded by the ghosts of the soldiers he fought. Unlike other ghosts he does not pass on when he runs out of energy and remains trapped in the mortal world tormented by the ghosts of the other soldiers. Yayoi enlisted his help promising to help him die.

Powers & Abilities
The Demon Seargent begins with his swordplay, despite his slimmer build he can easily block all the swings from the Old Old F tunnel ghost, in addition to his tough guard his body itself is incredibly durable.

He has 3 other weapons he draws in combat, each time he draws a new weapon his "prayer of debility" spreads with him as the center, anyone who is caught up in it becomes significantly weaker and begins suffering the pain of the wounds he got in war, this effect also effects him leading him to get weaker and weaker over the course of the fight, which is intentional as he tries to make himself weak enough that his opponent can kill him.
