There's a cover where Imu is cleaning a bathroom
and there's some siamese cats,

Siamese cats -> Siamese twins

Furo can mean immortal as well as bath.
There's a dragon statue in the cover (dragon - celestial dragon).

Imu took Lily's body.
And wants Vivi to be like a pair Siamese twins.

And Imu's transformation is a sapphire (blueish, like Lily/ Vivi hair) dragon.
