On the Verge of Death, He Transforms into an Onimusha and Reveals a Shocking Secret

[Attack on Titan] Semi-double, borrowing some settings, the plot is relatively slow This is a world where humans are trapped by demon spirits without knowing it. They just think that this huge city wall was built by their ancestors to protect humans from being invaded by alien beasts from the outside world. And these demon spirits are the gods who have protected humans for generations. Onimusha is a taboo profession. According to legend, all Onimusha are transformed from beings who are hovering on the edge of life and death. Because the last trace of nostalgia and care for the world exchanged the chance of reincarnation with the god of Hades, they became this half-life, half-dead alien who always fights for the god of Hades.
