Natsuki has long harbored a sense of regret about how his school life unfolded. He was a loner in middle school, and his attempt to rebrand utterly failed in high school. The rest of his academic career proceeded without incident, and he secured a standard job after graduation. Despite achieving a normal life and success, his lingering regrets continue to weigh on his mind. Natsuki will get his chance to change his fate sooner than he thinks. We’ll see what chances he’ll take when Haibara’s Teenage New Game+ (Haibara-kun no Tsuyokute Seishun New Game) premieres sometime in April 2026.
Kazuki Amamiya and Gin released the original Haibara’s Teenage New Game+ light novel series on December 1st, 2021. Hobby Japan has since published nine volumes in the HJ Bunko imprint. Misaomaru provided the art for the first manga adaptation, which ran from June 16th, 2023, to August 29th, 2024. Hobby Japan has since published two volumes in Comic Fire. Comochiya provided the art for the manga adaptation, which debuted on December 19th, 2024.

Getting the Best Ending with Haibara’s Teenage New Game+
Natsuki Haibara has looked back on his average and mundane life with nothing but regret. He has a steady job and the means to provide for himself in Tokyo, far from his parents’ home in Gunma, but the regrets persist. Natsuki was a gloomy loner in middle school, and his attempts to change himself led to failure and humiliation in high school. Through forces unknown, Natsuki awakens seven years in the past, a month before his high school entrance.
Natsuki didn’t question how he leapt backward from 2021 to 2014. He immediately set out planning how to improve his life by perfecting his high school debut. Natsuki spent the time before high school strength training. With a fit body, contact lenses, knowledge of the future, and a more mature personality, he feels prepared to face anything. However, old trauma haunts his every step as he seeks to undo the actions that led to his old wounds.
