Haibara-kun no Tsuyokute Seishun New Game
Natsuki Haibara is in his final year of college and has spent every spare hour of his twenties replaying the months between his middle-school graduation and the start of high school in his head. He goes to sleep on the night of his thesis defence and wakes up in his fourteen-year-old body, one month before the entrance ceremony he has spent the last seven years regretting. The series is his second high-school year, played as a coached campaign — strength training, online charisma guides, a deliberately rebuilt social circle — and the recognition that the people he is gentler to this time around are also rewriting their own lives in his rear-view mirror.
