Every night at 3:59 A.M., a forbidden minute stretches into an endless hour —the 25th Hour. A hidden realm where Akihabara is rebuilt from regret, and human guilt becomes power. Those pulled inside manifest a Lantern — a weapon born from their deepest wounds. Those who break become Wraiths, lost to the hour forever.

Kazutoro Hayashi, a burnt-out college student, slips into the hour by accident, mistaking its effects for exhaustion—until the injuries, lost time, and shadows follow him back into reality. Reina Kisaragi, a quiet and hardened survivor of the hour, carries a crimson Lantern and the weight of things she never speaks of.
The hour doesn’t ask why you’re broken.
It asks how long you can carry it.

And for those chosen by it…
the minute doesn’t pass. It watches.

Because in the 25th Hour, the real enemy is never the monsters.
“It is the part of you that believes you deserve to suffer.”
