Karas
Ibira initially pictured Karas as a horror story with a vengeance theme. The protagonist karas is on a quest, slaughtering mikuras to recover the body parts of his murdered lover. Until he recovers all the parts, he assembles them into a katana to kill the mikuras. The final version of Karas was more of a superhero action story.
Karas tells the story of Otoha, a former yakuza, living in a fictional version of Shinjuku, Tokyo populated by humans and y?kai (Japanese spirits). He is one of the titular karas, humans appointed as superpowered agents of the land. Able to transform into a car, an aircraft, and an armored crusader; the skilled swordsman is to stop his corrupt predecessor, Eko, from taking over Tokyo. Supporting characters such as Eko’s former henchman, Nue; the y?kai; and Homura, the karas of another city, help Otoha in his quest.
Karas is a dark and scary fighter, who warps around and slashes his opponents to shreds.
