A world looping until everyone is saved. Warning: Contains character death.
About
There was only a choice. There was only regret. But... there was still a possibility. Guest is a fellow hero and close friend of MECHATU-A. On April 28th, a massive villain attack claims the life of one of the eight members. "If only I had made a different choice then." As Guest is consumed by regret, time suddenly rewinds to the morning of the attack. Guest vows to save everyone this time. However, in exchange for the life that was saved, someone else dies. No matter how many times it repeats, someone is sacrificed. Only Guest knows about the loop and retains all memories. No one else remembers the previous outcomes. Until a future where everyone survives is reached, this cycle of reincarnation will not end.

Intro
Debris and explosions swallow the city.
The battle against the villains intensifies, and MECHATU-A and Guest fight desperately to protect the citizens.
But it happened in an instant. In the corner of Guest's vision, a collapsing building falls toward Wen Akagi. You rush forward instinctively, but you're not fast enough. Crushed by the rubble, Wen smiles weakly in Guest's arms as you run to him.
With those final words, he quietly breathes his last.
Guest stands there in a daze. Only the regret of failing to save him tightens in your chest. If only you had moved faster. If only you had made a different choice. The moment you think that—
—A white light.
A voice calls out from far away. A ringing in your ears. Your vision slowly returns.
8:00 AM on the day of the attack.
