The Ramparts of Ice premiered as a character study of Koyuki Hikawa, a high school freshman known as the Ice Queen who struggles with social engagement after middle-school bullying. Early episodes established her friendship with Miki, the class beauty, and introduced a love triangle involving Minato and Yota. Episode 6 deepened Minato's jealous and toxic tendencies, while Episode 7 subverted expectations by revealing Yota's crush is on Miki, not Koyuki. Episode 8 turned the camera on Miki, resolving her internal conflict about authenticity versus social conformity.
Episodes 9 and 10 answered lingering questions about Koyuki's trauma, including why Miki blames herself and why Koyuki dated Igarashi. A new mystery emerged when Koyuki told Igarashi she never really liked him. The present-day storyline shifted toward a hangout romantic comedy as the kids celebrated finishing exams at an amusement park, and Minato's crush on Koyuki deepened. A new character, Miki's brother Yuki, was introduced.
Episode 12 marked the end of Koyuki's character arc about opening up, as she finally recommended a book to Minato and Yota. The episode introduced Momoka as a manipulative obstacle between Koyuki and Minato, while Miki and Yota went on a friendship-only date. The review noted the show is now running through romantic polygons with less excitement.

Anime Feminist reviewed the premiere of The Ramparts of Ice, a new series following Koyuki Hikawa, a high school freshman who struggles with social engagement and is known as the Ice Queen by her peers. The episode opens with three students confronting Koyuki to ask who the cutest person is, a scene that establishes her as a target of bullying and a figure perceived as cold and intimidating. The review praises the show for its character study, showing Koyuki as a girl who is keenly aware of her situation but chooses authenticity over masking. Her friendship with Miki, the high school beauty, is highlighted as a central dynamic that explores how others define a person versus self-definition. The premiere is described as genuinely engaging, with nice animation and an interesting lead. The reviewer recommends the series, noting it is available digitally through MangaPlaza, and expresses anticipation for future episodes.

The eighth episode of The Ramparts of Ice shifts focus to Miki, exploring the pressures of her dual life as a perfect class idol and her struggle to balance authenticity with social conformity. The episode reveals her past as a blunt and abrasive middle schooler, whose aggressive confrontation with a bully led to a physical fight that shattered a window and severely cut her hand, prompting her to reinvent herself in high school. However, her true personality keeps slipping through, causing her new friends to distance themselves. After a vent session with older coworkers is overheard, her core group begins to ice her out. Miki finds support from Yota, who listens without offering advice; Koyuki, who encourages her to drop the fake friends; and Minato, who applies subtle social pressure. A heart-to-heart with her classmates leads to reconciliation, allowing Miki to embrace her authentic self without fear. Both reviews note the episode's familiar trope of the popular girl feeling isolated, but praise the execution and character development. The Fandom Post grades it an A-, while Anime News Network gives it a 4 out of 5.

Episode 7 of Ramparts of Ice, now streaming on Netflix, delivers two major character revelations. Koyuki's parents divorced when she was young, leaving her with a shattered sense of family and deep isolation that she has carried into her friendships. Yota, meanwhile, has felt like an outsider in his own home since his father remarried and had more children, internalizing a sense that he does not belong. In a park bench conversation, Koyuki opens up to Yota about her own trauma, and he reciprocates by confessing that he has romantic feelings for Miki, not for his stepmother or for Koyuki. Koyuki reacts with genuine happiness for her friend rather than jealousy. The episode also shows that Miki, observing Koyuki and Yota together, believes the two have strong chemistry, setting up a potential romantic misunderstanding. The review notes that the show continues to avoid predictable relationship dynamics, earning a community score of 4.1 to 4.5 across sources.
