DESCRIPTION
An open-world-style (mostly!) role-playing game where you can act completely freely inside a world trapped in a 1-month time loop—all leading up to the moment “My little sister goes insane, mutates into a monster, and destroys Tokyo.”
The protagonist (the big brother) crosses paths with a mascot character who claims to be a Spirit God… and who also happens to have a beard growing out of his biceps. This Spirit God drops a bombshell: you are “destined to be killed by your little sister in the end.”
In fact, your sister already casually wanders around the house holding a kitchen knife, possessing the kind of personality where she’ll try to stab her big brother out of sheer, impulsive rage.
The protagonist tries his best to survive by following the Spirit God’s guidance, but since he is inevitably caught in the cataclysm and dies at the end of the month, the Spirit God triggers a time leap—forcing you to repeat June 1st for eternity!
Use the loop to its fullest and save your little sister from her tragic fate of destruction!
…Or at least, that’s the narrative setup, but you (the player) don’t actually have to save her at all if you don’t want to.
