Fuku (フクちゃん Fuku-chan) is Mikeru's "right-hand man" and messenger to his servants. Though he is small and appears to be completely useless, he is capable of ordering Mikeru around and has a bigger role towards the end of the second season.
Fuku is the messanger of Michel, but he is assigned to control him in case he refuses to fight. He often torments the Black Beauty Sisters calling them failures, and in the manga he torments all of Michel's minions except for Alala. He oftenly shows up to assist Alala and comes to look after the Black Beauty Sisters instead of Michel. Fuku is revealed to have a much bigger job at the end of both the anime and manga.
Fuku is very annoying and taunting towards every one of Mikeru's servants. He knows the big secret about Mikeru's true self and is easily startled when the servants revealed the big secret in front of Mikeru himself. He's extremely annoying, which usually caused him to get hit, swinged, or just smacked. This abuse is usually inflicted by the Black Beauty Sisters. He is usually without words toward Alala whenever he gives her power to attempt to capture the Mermaid Princesses.He has a bit of a crush on Alala even though she set him on fire.
Fuku is like a super deformed angel or bird with a human head and a bird's body. He has magenta hair and black pupils for eyes and sometimes has the shy pink mark indications on his cheeks. It is not indicated in the anime strongly, but Fuku is also the bird whom is always locked in the cage in Mikaru's room. He is probably there to surveillance her activity and moments when she can be taken to strengthen Mikeru's power and strength.
