Cain hid his ghoul nature behind the guise of an occult enthusiast, using the cover to stalk the members of Kamii University's paranormal circle. When he set his sights on Hideyoshi Nagachika, the plan collapsed: the target saw through him, and investigators soon put the predator down.
Dark-purple hair cropped to about chin length framed the face of a fairly ordinary man in his early twenties, who favored biker-style gear.
Rather than a genuine scholar, Cain was a predator wearing a researcher's mask, drawn to the paranormal club at Kamii University as a hunting ground. Hideyoshi Nagachika became his chosen prey, but the young man proved too clever and flipped the encounter around, after which ghoul investigators arrived to finish Cain off. His name is a deliberate biblical echo: in the Book of Genesis, Cain was Adam and Eve's firstborn who murdered his brother Abel out of envy, a link Kaneki himself points out in the Days novel.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
