Synopsis

Fresh off the successful crowdfunded film starring Chizuru Ichinose, Kazuya Kinoshita slips back into the tangled routine he’s built around half-truths. He continues to present Chizuru as his girlfriend of over a year, even though their connection still largely runs through the rental girlfriend service that brought them together.

After attending a private party with Chizuru, Kazuya resolves to finally put his feelings into words. But with his trial girlfriend Ruka Sarashina and his ex-girlfriend Mami Nanami still in the picture, every step toward an honest confession becomes another test of how long he can maintain the façade—and whether he can untangle his increasingly chaotic love life.

Otaku Consensus

Season 4 lands as a deliberately uncomfortable continuation rather than a reset: Kazuomi Koga’s direction and Mitsutaka Hirota’s series composition keep the post-film fallout moving through tightly staged social-pressure scenes, with TMS Entertainment leaning on reaction timing and Kanna Hirayama’s polished character designs more than spectacle. Its 6.16 MAL score and 60/100 AniList score reflect a split verdict: loyal viewers value the sustained fake-relationship tension and private-party confession build-up, while the dominant criticism is that Kazuya’s evasions and the harem interference still stretch emotional progress past many viewers’ patience.

Why You Should Watch

Watch Season 4 if you want a rom-com that treats embarrassment like suspense: pauses, glances, bad timing, and social obligations do as much damage as outright rejection. It scratches the same fake-relationship itch as Nisekoi, but with an adult urban setting and a more transactional edge; it also shares Kaguya-sama’s obsession with overthinking, minus the clean battle-of-wits structure. The appeal is not wish fulfillment so much as controlled discomfort: TMS Entertainment and director Kazuomi Koga keep the comedy rooted in body language, while Kenichi Maeyamada’s music helps the show swing between panic and sentiment. Viewers who enjoy messy romantic stasis, visible character flaws, and harem tension that refuses to tidy itself up will get the most out of it.

Key Characters

K
Kazuya Kinoshita
Kazuya remains one of modern rom-com anime’s most polarizing male leads because the show foregrounds his panic, rationalizations, and self-sabotage instead of sanding them into easy charm.
C
Chizuru Ichinose
Chizuru is the franchise’s emotional anchor, compelling because her professional composure constantly forces viewers to question where performance ends and personal feeling begins.
R
Ruka Sarashina
Ruka gives the season its most aggressive romantic pressure, functioning less as a passive rival than as a walking deadline for Kazuya’s indecision.
M
Mami Nanami
Mami’s presence keeps the series from becoming a closed harem loop, since fans read her as the character most capable of turning private lies into public consequences.

What Makes It Stand Out

1
The season is a compact 12-episode summer 2025 cour, airing from July 5 to September 20, 2025, which gives the post-film material a defined weekly pressure-cooker shape rather than a long-running sprawl.
2
TMS Entertainment handles animation production, with Kanna Hirayama credited for character design; the season’s visual identity is built around expressive close-ups and recognizable model consistency rather than action-driven spectacle.
3
Director Kazuomi Koga and series composer Mitsutaka Hirota are the key adaptation pair, a relevant detail because Season 4 depends heavily on pacing awkward conversations, withheld confessions, and escalating social interruptions.
4
AniList’s tag spread is unusually concentrated: Fake Relationship sits at 100%, Primarily Adult Cast at 93%, Female Harem at 92%, and Unrequited Love at 80%, clarifying that the show’s appeal is structured tension rather than simple dating progression.
5
Kenichi Maeyamada provides the music, while Hajime Takakuwa serves as sound director, giving the season a staff setup aimed at quick tonal shifts between cringe comedy, romantic sincerity, and melodramatic pressure.

Fun Facts & Trivia

Fun fact 1: Reiji Miyajima is credited as the original creator, so Season 4 remains directly tied to the manga source rather than being presented as an anime-original continuation.
Fun fact 2: The season’s database reception is sharply middling: MAL lists it at 6.16/10 from 37,708 votes with a rank of #9979, while AniList records a 60/100 score and 491 favourites.
Fun fact 3: AniList labels the series with a 79% Prostitution tag, a blunt database classification tied to the rental-girlfriend service framework that distinguishes it from more conventional fake-dating rom-coms.
Fun fact 4: The art and image pipeline includes Minoru Akiba as art director, Akemi Nagao as color designer, Shintarou Sakai as director of photography, and Yumiko Nakaba as editor, showing how many specialized roles shape the show’s controlled urban-romance presentation.
Fun fact 5: Despite being categorized under Comedy and Romance, its theme metadata emphasizes Adult Cast and Harem, which helps explain why the season’s conflicts revolve around social reputation, emotional debt, and overlapping romantic claims rather than school-club antics.
