Second chance at high school is relatable fantasy—everyone wishes they could redo their teenage years armed with adult knowledge and perspective. Yuto Uemura voicing socially anxious protagonist fits; his ability to convey vulnerability suits Natsuki's struggle with regret and determination. Three additional cast members expand romance options; adding Kanna Nakamura, Aya Yamane, and Sayumi Suzushiro suggests multiple potential love interests. Learning from past mistakes creates compelling growth; watching Natsuki avoid his previous errors while navigating social dynamics promises satisfying character development.

A brand-new trailer was released for the Haibara's Teenage New Game+ anime before its planned April 2026 broadcast today, previewing the voices of Yuto Uemura as Natsuki and Kanon Takao as Hikari, while also revealing three additional cast members.

The Story

J-Novel Club describes the story:

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!
