Shisei Houjou is a kind and affectionate girl who shares a deep bond with her cousin, Saito Houjou. She is always there to console him whenever Akane gives him a hard time and has even told him that if he ever became homeless, she would willingly join him on the streets, emphasizing her unwavering loyalty.

Despite her gentle nature, Shisei has a mischievous side. This is particularly evident when she discovers Saito and Akane’s marriage and jokingly demands hush money from Saito, though it is implied that this was not a serious request. Her playful personality adds a lighthearted contrast to the group’s interactions.

However, in Volume 7, it is revealed that Shisei’s childlike attitude is merely a façade. Beneath her seemingly innocent exterior, she is actually highly intelligent, serious, and an expert strategist. She harbors the belief that she could reshape the world according to her own vision, a confidence stemming from her inherited talents and ancestral lineage. Her pragmatic approach to achieving her goals is further reinforced by her willingness to “dirty her hands” if it means securing Saito’s happiness, showing a far more calculated and ambitious side to her personality.

Shisei Houjou is a petite, doll-like girl with long silver hair, which enhances her delicate and ethereal presence. She wears the standard school uniform, but her sweater is slightly oversized, causing it to sag over her left shoulder, subtly revealing her shirt underneath. This slightly unkempt detail adds to her unique charm, complementing her cool yet affectionate demeanor.

Shisei Houjou is the cousin of Saito Houjou, sharing a close sibling-like bond due to their upbringing together. She possesses a doll-like appearance and exudes a captivating, cool attitude, which contrasts with her affectionate and straightforward personality. Despite her seemingly simple and gentle nature, Shisei is remarkably insightful, often providing support and guidance whenever Saito relies on her. Her combination of elegance and perceptiveness makes her a unique presence in Class no Daikirai.

Shisei Houjou was born into the prestigious Houjou bloodline, a lineage known for its exceptional intelligence and strategic prowess. As a direct descendant, she inherited a high IQ from her ancestors, granting her an innate ability to analyze situations and devise intricate plans. This natural intellect sets her apart, allowing her to manipulate circumstances to her advantage while maintaining a composed and unassuming demeanor. Her upbringing within the Houjou family has shaped both her outwardly affectionate personality and the calculated strategist hidden beneath the surface.

Saito Houjou
Shisei adores and deeply cherishes her cousin Saito Houjou, often comforting him whenever he is verbally mistreated by Akane Sakuramori. She expresses her affection through small gestures, such as hugs and head pats, demonstrating her unwavering support for him. Her devotion is so strong that she has even stated she would abandon her family and live on the streets with Saito if his grandfather ever disowned him.

Despite her affection, Shisei also enjoys teasing Saito, as seen when she jokingly demanded hush money from him in exchange for keeping his marriage a secret. However, it is later revealed that her feelings for Saito extend beyond familial love, she harbors romantic feelings for him as well. She wishes for him to stop treating her like a child and instead recognize her as a woman.

In the epilogue, during Saito and Akane’s wedding, Maho Sakuramori suggests that Saito should form a harem, as none of the girls are willing to give up on their love for him. Shisei is shown to be supportive of this idea, expressing her desire to stay by Saito’s side forever.

Akane Sakuramori
Shisei harbors a degree of disdain for Akane due to her hostility towards Saito, often witnessing the way she treats him. However, despite her initial dislike, Shisei is still willing to hear her out and make an effort to understand her perspective.

Reiko Houjou
Reiko is Shisei’s mother, though little is known about their relationship.

Rui Houjou
Rui serves as Shisei’s personal maid, attending to her needs and ensuring her well-being.

Maho Sakuramori
Shisei considers Maho her rival, as the two frequently compete over Saito, each vying for his attention. Their rivalry adds a dynamic element to their interactions, as both girls view Saito as their “big brother figure” and often challenge one another over their affections for him.

Himari Ishikura
Not much is mentioned about Shisei’s relationship with Himari Ishikura.

Saito’s Parents
Much like her mother, Shisei despises Saito’s parents for their abusive treatment of him. She openly calls them “foolish cowards,” condemning their actions and expressing her deep resentment toward them.
