Synopsis
College student Natsuki Haibara may have his future neatly lined up, but his mind often drifts back to high school—when social anxiety and his weight kept him on the outside looking in, and every attempt to reinvent himself ended in embarrassment. After wishing for a chance to do it all over again, he wakes to an impossible gift: he’s been sent back to the days just before his high school debut.
With a month to prepare, Natsuki throws himself into getting in shape and arrives on day one determined to change the story. He manages to make a strong first impression, reconnects with faces he remembers, and meets Hikari Hoshimiya—the crush he never truly got over. As he spends time with Hoshimiya and a growing circle of friends, he rediscovers his passion for basketball and picks up a part-time job at a local café, only to find that a fresh start also brings new hurdles he’ll have to face to make the most of his second shot at adolescence.
Otaku Consensus
Haibara's Teenage New Game+ lands as a modestly received school rom-com whose best notices point to its diverse social cast, low-key emotional beats, and the way Misuzu Hoshino's direction keeps the basketball and café material grounded in everyday teen routine. The prevailing criticism is just as consistent: after opening with a time-manipulation hook, Keiichirou Oochi's series structure often settles into familiar slice-of-life romance patterns, leaving viewers split between “pleasantly captivating” and “underwhelming.” With a 6.61 MAL score and 66/100 AniList score, its reputation is less cult breakout than niche comfort watch.
Why You Should Watch
Watch Haibara's Teenage New Game+ if you want a ReLIFE-adjacent second-chance youth story that trades heavy sci-fi explanation for school-club rhythm, part-time-work texture, and rom-com social repair. It is best suited to viewers who like the emotional housekeeping of adolescent drama: awkward popularity shifts, friendship maintenance, basketball as confidence training, and café scenes that let the cast talk outside classroom hierarchy. Compared with flashier time-reset anime, this is smaller and more domestic; compared with gag-first school comedies, it is more invested in rehabilitation than punchline density. The appeal is not surprise mythology but the everyday mechanics of becoming easier to be around, which is why its mixed reception makes sense: viewers seeking sharp genre escalation may bounce, while slice-of-life romance fans may find the restraint comfortable.
Key Characters
- NNatsuki Haibara(VA: Yuuto Uemura)
Natsuki is interesting less as a wish-fulfillment lead than as a self-editing protagonist whose social progress is framed through fitness, basketball, work habits, and deliberate conversation rather than instant charisma.
- HHikari Hoshimiya(VA: Kanon Takao)
Hikari functions as the series' romantic focal point, but fan discussion tends to place her within the broader ensemble dynamic rather than treating her as the only reason Natsuki's new school life matters.
What Makes It Stand Out
- 1
The series was produced by Studio Comet as a complete 12-episode Spring 2026 TV run, airing from April 3 to June 19, 2026, which gives it the compact pacing profile of a single-cour school romance rather than a long-form adolescence saga.
- 2
AniList tags the work at 100% for both Age Regression and Time Manipulation, but its secondary tags reveal the real emphasis: Rehabilitation at 85%, School at 80%, Basketball at 50%, and Restaurant at 26%. That tag spread matches the reception that the show becomes more slice-of-life routine than genre puzzle.
- 3
The production separates original character design and animation character design: Gin is credited with the original character designs, while Hiromi Ono handled the anime character designs, a useful distinction for viewers tracking how source-style art is translated for TV animation.

The critical split is unusually easy to quantify: MAL users placed it at 6.61/10 from 11,672 votes with a #7099 rank, while AniList sits close at 66/100 and lists 353 favourites. Its scores point to a show with a defined appreciative niche rather than broad seasonal dominance.
- 5
The two recurring non-classroom spaces highlighted by the data are basketball and the local café, giving the romance a social geography beyond desks and rooftops. That structure is one reason positive reactions singled out the cast variety, while negative reactions felt the time-travel setup faded into standard high-school beats.
Fun Facts & Trivia
- Fun fact 1
- Kazuki Amamiya is credited for the original story, while Keiichirou Oochi handled series composition, making the anime's balance between time-manipulation premise and school-romance routine a staff-level collaboration rather than a director-only choice.
- Fun fact 2
- The main voice cast is led by Yuuto Uemura as Natsuki Haibara and Kanon Takao as Hikari Hoshimiya, with the official character list in the provided data naming only those two as main roles.
- Fun fact 3
- The show's visual pipeline lists Seo-Gu Lee as art director, Aiko Yamagami as color designer, Shintarou Sakai as director of photography, and Hideaki Murai as editor, a full set of credits that helps explain the TV production's division of background, palette, compositing, and pacing responsibilities.
- Fun fact 4
- Yayoi Tateishi served as sound director, the role responsible for coordinating vocal performance tone, effects placement, and overall audio continuity rather than composing the music.
- Fun fact 5
- Online impressions were sharply divided during and after release: one review framed it as a captivating romantic slice-of-life with unexpected twists and emotional depth, while another said the initial time-travel idea dwindled into a standard high-school romance.
