Imu seems to have a satan fruit, but some sort of satan who can grant powers or immortality in exchange for your soul
Which means Imu's power is ultimately "mephisto" most likely, the demon that beguiled Faust, and gave him all of his dreams and riches in exchange for his soul.

It seems like there might be some sort of rules for how the reversi works, but the more broken the fruit the less exact the rules are. With mystical zoans anything can count as an "animal". Deers are animals, gorillas are animals, humans are animals, but with mystical zoans even gods or devils can count as "animals" apparently. Which is why they're the top class of fruit.
