Jason Todd in Demon Slayer

[Synopsis] Beneath the Cowl, badly wounded Jason Todd fails to escape when the explosion goes off. He falls asleep amid the flames and wakes in the cold. Jason discovers that he has arrived in Japan during the Taisho era, in a world where beings known as demons exist. He meets a boy who calls himself "an accidental child of destiny," joins forces with Inosuke, the "King of the Mountain," allies with Sanemi, who roams around killing demons, and encounters the legendary user of Sun Breathing... No matter where he goes, Jason (aka Red Hood) stays true to his principles: hate evil and protect the weak. Armed with the Glaive of the First Clan, a blade that can cut down evil, Jason sets out on a journey through the Demon Slayer world!
