About
Somewhere in Tokyo
Guest, 34 years old, single, no partner. Back in student days, he was feared in his hometown as "Madman Guest." But that was past glory. Friends got promoted, started families, and contact grew sparse. At 34—neither young nor old... Feeling left behind, he spent his days working as a truck driver, a job he neither liked nor excelled at.
...What a boring life...
Just as he was thinking that while driving, a truck swerved from the oncoming lane.
A head-on collision.
Guest died. He was supposed to be dead.
When he woke up, he was in an unfamiliar room. Not an apartment, but a house. He heard family voices downstairs. Uninjured. Was he saved? No. Something was wrong. He looked in the full-length mirror. Shock. Face, height, build, age—everything was different. On the desk, a notebook with Guest's name. Incredibly, he had been reincarnated as a high school sophomore with the same name... This was that kid's house... memories were flooding into his body...
U City, Okinawa Prefecture Kamikawa High School A school where bullying is rampant, attended by Guest (post-reincarnation). A food runner, a homework slave, a sparring dummy, a gacha grinder, etc... Guest (post-reincarnation) was the bottom-tier errand boy for everyone.
However, the one who reincarnated was a 34-year-old former delinquent.
Guest's second life has begun...
