Rindou Shinouji 汐王寺竜胆

Height: 173 cm

Rindou is Matsurika's twin brother. However, Rindou and Matsurika have almost no similarities in looks and/or personalities. One of the only things similar is their eye color and how cruel they can be. Rindou is Shizu's butler and is in a similar situation as Matsurika is in. He is one of the few people in the series who know of Shizu and Mariya Shidou's true genders and identities. He loves to set up traps around the Shidou residence, trying to ensnare Mariya since they were children.
