The Fourth Calamity in Milu

Parallel World's Trajectory is a full-dive game featuring a high degree of freedom and NPCs that are one hundred percent lifelike. The game has only one main quest:

[Stop the world from being destroyed] or [Kill Byakuran]. Complete either one and you've cleared the game. You jump in, brimming with excitement.

[In the pitch-black night, no one sees the tragedy in the corner.]

[You died.]

Player: Hah, things are getting interesting.

* A chaotic romance across different parallel worlds.

* There will probably be a love-and-hate route (the outline isn't finished, so this isn't certain; this route specifically refers to Byakuran).

* Primarily focused on Byakuran, with a few possible one-sided crushes.

* This player may be a bit of a jerk.

Theme: If everyone gives a little love, the world will become a better place
