YMMV / First: Do No Harm

• Complete Monster: Even before he became a demon, Marshall Eccelstein was a horrific monster of a husband who kept Violet chained to a wall naked and brutally beat her bloody every day. By the time of the story, he has figured out a way to reach Vanilla, Katherine, and Kidari, and sends specialized assassins to kill them and capture his daughter Rosalina, planning on making the assassins torture Violet to death afterwards. When Astaroth turns him into a demon, he rapes and kills Amy and then kills and zombifies Daniel, planning to force Vanilla to kill him. After he is expelled from his body and takes the name Cerununnos, he drives an entire military base insane before driving violent criminals insane and releasing them from prison, taking sick joy in the chaos that ensues. He then begins killing random officers and civilians for fun before being stopped by Vanilla's brother Shoji, learning that there are 16 alive members of the Jackson family in the process. Cerununnos, while planning to kill the Jackson family, encounters a bus and stops it, intending to slaughter everyone on the bus and then kill a family with the bus before being defeated.
