Houjou, Saito

北条才人

He is Akane Sakumori's classmate and natural adversary. He frequently argues with Akane and struggles to get along with her. Despite being highly intelligent and achieving top grades, he often exhibits unconventional behavior and tends to be absent-minded. He marries Akane to take over his grandfather's Houjou group.
Saito is a young man of average height, 175 centimeters, with a lean build and short black hair. He typically wears the standard school uniform.
Saito is mostly laid back and calm, sticking to his own space. A slacker by nature, Saito rarely exerts himself and has a rather extreme minimalist disposition; he limits his dietary habits to nothing but cup noodles, vegetable juices, and protein shakes. He is also generally very unhygienic, not bothering to wash dishes until they pile up, taking garbage out once per month, and even questioning the need for bathing.
Despite his laziness, he always scores first place in exams, meaning he is academically competent and intelligent enough that he does not need to study, due to being born with photographic memory. Saito actually loves gaming and has a liking for horror games.
It is hinted that he picked up some of his habits as a result of his parents' abandonment and emotional abuse, while not fully adjusting to life with his extravagant grandfather. When Akane prepared him proper food, he was delighted at eating something normal, which meant a lot to him, showcasing a degree of loneliness.
Saito desires to inherit the Houjou Group more than he desires to put up with his grandfather's unreasonable demands.
Though generally composed, his interactions with Akane easily put him into defense mode and bickering. Nonetheless, his daily life with her forces him into a bit of introspection and to be more cooperative.
Saito was born with photographic memory inherited from his ancestors. As a result, he was heavily neglected by his parents, who were exiled from the Houjou family. Once his grandfather learned that Saito was not an ordinary child, he immediately groomed him to become his successor of the Houjou Group, separating him from his parents in order for him to stay with Shisei's family.
