The light novel series Haibara’s Teenage New Game+ (a.k.a. Haibara-kun no Tsuyokute Seishun New Game in Japanese) by Kazuki Amamiya is getting an anime adaptation! HJ Bunko, an imprint of Hobby Japan, shared the news online this week along with the above visual.
Not a lot of information is available yet, like any people involved, what studios are doing this, or when we might expect to see the anime debut. We’ll have to wait to learn more. In the meantime, the light novels are available for American readers thanks to J-Novel Club, which gave this description for the plot:
Haibara’s Teenage New Game+ Plot
We all have embarrassing memories or deep regrets from high school, right? Socially anxious college senior Natsuki Haibara sure does. When he thinks back on that time of his life, all he has are fleeting fantasies of a happy adolescence that could have been. Imagine his bewilderment and surprise, then, when he inexplicably finds himself seven years in the past—one month before his first year of high school!
Can Haibara avoid his previous mistakes, make his way to the top of the school social pyramid, and end up with the girl of his dreams? Or will he be forced to relive three years of solitude as the most hated guy in school? He’ll need all the help he can get in order to succeed, from a workout regimen to online how-to guides, a childhood friend, and plenty of sheer willpower. Watch as Haibara takes a second shot at his teenage years!
So far eight volumes are available to read. Things will start winding down with the ninth volume, which launches us into the last arc. That’s scheduled to ship in Japan today.
The 2020 HJ Novel Awards honored the novels with the grand prize. There is also a vertical comic adaptation of it from Misaomaru that’s in full color instead of monochrome. The light novel series had its first physical book released in late 2021.
