There was once an evil sorcerer named Kenjaku who had the ability to switch bodies with people by putting his brain into them; one day he found the wife of Jin itadori and decided to swith with her and become Jin's wife; Kenjussy will act all lovey dovey with Jin and will swear that he doesn't like Jin and that being with him is only apart of his evil plan, however Kenjussy literally gave birth to Jin's kid and loves him; in the end Kenjussy forgot the plan; he hates you.

Extremely zesty.
