Kurashiki Reina

Reina is one of the main protagonists of the series, standing out for her seductive charm and manipulative skills. With a confident and captivating personality, Reina knows how to use her attractiveness to influence and dominate those around her. However, her relationship with her mother, Reika, is marked by tensions and a mix of admiration and resentment, reflecting her internal struggle between the desire for independence and her need for approval. Despite her confident façade, Reina hides a more vulnerable side that reveals itself in moments of introspection or in situations of high emotional conflict. However, Reina’s ultimate weakness is her inability to control her tongue, which leads her to accidentally embarrass herself on occasion.

Kurashiki Reika

Reina's mother, Reika, is a strong and determined woman, whose personality combines authority and maternal affection. Her firm and disciplined exterior often hides a softer emotional side, which emerges in her interaction with Reina, especially in her attempts to guide her without stifling her independence. Reika is an influential figure who, despite her good intentions, tends to project her expectations onto her daughter, leading to conflict but also moments of deep emotional connection. Reika’s arrogance is also her ultimate weakness. With increased pressure in her personal life, Reika’s dominance will come crashing down with a little push towards submission

Miyajima Sakura

Sakura is the only child of a family devoted to martial arts, where she has grown up under strict discipline. As president of the kendo club, she is respected for her dedication, strength, and skills. However, her rigorous upbringing has limited her development in social and emotional aspects, making her naive and sometimes clumsy in matters of love and friendship. Sakura strives to balance her personal life with her responsibilities, looking for ways to step out of her comfort zone while maintaining her integrity. Her naïveté to the ways of the world make her vulnerable to abuse by those in authority over her. Her deep respect for those teaching her can ultimately work against her in some cases.

Miyajima Tsubaki

Sakura's mother, Tsubaki is a woman who shares her daughter's passion for kendo, acting not only as a mother, but also as a mentor. She is known for her protective and loving nature, although she can be strict when it comes to discipline and family values. Tsubaki is deeply committed to Sakura's well-being, but often struggles with the dilemma of allowing her freedom to grow while protecting her from failure or pain. While she is largely focused on discipline and family, Tsubaki has a high sex drive, which she keeps hidden. However, with the right motivation, she has the potential to be a complete cumslut and sadomasochist.

Obata Yui

Yui is a sweet and kind character who acts as an emotional pillar within the group of friends. Her positive approach to life and calm nature make her someone easy to rely on. She is often the mediator in conflicts and offers advice with a balanced perspective. Although she appears shy, Yui has an inner strength that emerges when she is faced with personal challenges or when her loved ones need her unconditional support. While Yui is an innocent girl on the surface, she harbors a darker side. She spends many late nights watching public exhibitionist porn, and fantasies about herself being taken advantage of in populated places.

Obata Natsumi

Yui's sister, Natsumi is energetic and outgoing, representing the perfect contrast to Yui's calmness. Her playful and competitive personality brings dynamism to the group, and her ability to lighten the mood in tense situations makes her well-liked by others. Despite her carefree nature, Natsumi is deeply loyal and has a strong sense of responsibility towards her sister and friends. Natsumi’s lightheartedness can often make her oblivious to sexual situations, making her exceedingly vulnerable to abuse or manipulation.

Takamine Misao

Misao is a serious and reserved figure, whose thoughtful personality adds a mature perspective to the group. She is often found observing and analyzing situations before acting, allowing her to make balanced decisions. Although she can sometimes appear distant, her calm demeanor and ability to understand others make her a trusted and respected figure. Her seriousness hides a deeply emotional side that she only reveals in intimate moments. Misao’s ultimate weakness is her soft heart. A simple tug on her heartstrings can open her to manipulation and abuse.
