Kaidou Shima (海棠 蒔麻; Kaidou Shima) is a supporting character in the "Super Lovers" manga and anime written by Abe Miyuki. He is the younger twin brother of Aki Kaidou and lives in the Kaidou household with his three other brothers. He is currently attending college with his older twin brother Aki.
Shima has black hair and brown eyes. He wears glasses and always looks quite mature with his casual-formal wear. Shima's hair is short and doesn't look as messy as the other three brothers' hair.
Shima is responsible, composed, mature, and respectful. He is a very good natured individual that is observant to the people around him. Shima stays self-controlled and calm.
Shima and his brother Aki are half-brothers to Haru. Their father was previously married to Haru's mother. He grew up with Aki at their maternal grandparent's place and they both moved in with Haru after graduating from high school. Shima was the one to notice that their family register had changed, but he has never had a problem with accepting Ren into the family.
Aki is Shima's older twin brother. Despite this Shima is taller than him. As siblings, they've always been with each other.
Haru is Shima's half brother from Canada. He was fostered by Shima's parent from Haruka and moved to Japan to live with the Kaidou family. Haru became a father figure for Shima and Aki ever since their parents died in a car accident. He worked hard as a host to get Shima and Aki into college.
Ren is Shima's adoptive brother. He was not accepted at first by Shima and Aki, but he eventually grew on them. Ren was announced to be in the Kaidou family by Mikiko, the family lawyer. They all ended up living together after Haru quit his job and rented property from Mikiko.
