Kogure Nikaido

 "I love her. I want to trample her to a pulp." Kogure is

Appearance
Kogure has shining black hair and evil red eyes. He usually was seen to wear very neatly. Before he was nominated to be the next head Nakamura’s family (when he’s still live inside the main house), he wore rougher clothes like T-shirts and jeans because it suits his idea of life. He hates slovenliness, so he dresses carefully and always wears neatly tailored clothing. He doesn’t always wear accessories, unless it’s something small to accent Western clothes.

Personality
Kogure hides his true self under a pretense of constant silliness. He's kind to Yunoki and generally friendly but sometimes his eyes are cold. It's not entirely clear whether he has Sakura, Yunoki, Aoki or anyone else's best interest at heart but he obviously plotting something that involves Sakura.

Kogure seems like a pervert and a laid back character but he has another side of himself. He can be surprisingly mature, thoughtful and gives rather sage and insightful advice to other characters. In the manga, it is revealed that he is also quite cunning and somewhat dark-humored.

Background
Kogure's background is unclear in Season 1 and it was only revealed that he is the next head of Nakamura's family, Sakura's stepbrother and living under the same roof with her. Season 1 didn't reveal the the reason why Kogure was not in Sakura's past and why he was abondoned by his parents.

Only in Season 2, Kogure's background was revealed. The reason behind why he's living with Sakura was because his grandmother, the previous head family asked him to get to know his long lost stepsister.

Sakurairi Nakamura
His stepsister. Kogure knew Sakura is his stepsister since Sakura was born because he was there and held her since she was a baby. He got seperated with her when Sakura turned 3 years old.

Kogure always thought that he hated Sakura but the truth is he has always loved her. Because he was confused and don't know what to do with those feelings, he confined Sakura in an isolated room for months. Yun words of anger reached him and made him realize his love towards Sakura.

Iharra Yunoki
His bestfriend. At first Kogure thought that Yunoki is trying to play with Sakura's heart. He is jealous wiht Yunoki because he helped Sakura while she was hospitalised when she was young.
