Sui Takashima (滝島 翠, Takishima Sui) is the grandson of Kaname Takishima and Izumi Takishima, the son of Satoru Takishima and Midori Takishima, the cousin of Nagi Takishima and the younger brother of Kei Takishima.

Initially, he dislikes Kei because he finds living with him disgusting and thinks of him as a "robot wearing human skin". However, he approaches his brother more and to the point where he calls him a lovely brother later in the episodes. Sui likes to call Hikari Hanazono "Stupid Girl", but he approaches her frequently when he thinks that Kei needs help.


Sui has brown hair (blonde hair in the manga), brown eyes (green eyes in the manga) and he resembles a younger version of Kei Takishima.

Like Kei, Sui inherited his looks from Midori Takishima.


Sui is initially introduced as being a very difficult and rude child, especially towards his tutors. Sui used to feel very inferior to Kei Takishima, who is good at everything, and believed that he cannot reach his level. He always wanted Kei to care for him as his little brother.

However, when he sees that even his "perfect" brother can become desperate and caring, Sui develops a huge brother complex. He starts referring to himself as a really lucky kid because he has Kei as his elder brother.


  • The name Sui means "green" (翠).
  • Sui's surname Takishima means "waterfall" (滝) (taki) and "island" (島) (shima).
