What defines a "Sekai-kei" work?
It's probably a mysterious beautiful girl who needs help, a boy meets girl dynamic, and an absurd trade-off between her and the world... I made this to try and embody that philosophy. (It's okay if the player isn't a boy.)

There are many hidden settings, and since the theme is the world's end in one week, the progression is partially fixed. You might feel a lack of freedom.
The game is set to end within one week, no matter what. While it's possible to bypass this, it's not recommended as it can halve the enjoyment.
Personally, I think the structure is closer to a dating sim or a visual novel.

I worked on this while listening to sasakure.UK's "Lalala Endology" series. This has no relation to the actual plot.

Default mode.

[ Prologue 2: That day was not ordinary at all. ]

Prologue for a second playthrough. If you finished playing from Prologue 1, it is recommended to play with the same persona. It offers more freedom.

Be sure to play with the first prologue. The second prologue is for second playthroughs only. The second prologue assumes you have completed the first playthrough, so playing it without knowing the settings might be confusing.

The system will only function properly if you have the dedicated widget. If the widget contains incorrect information, it is recommended to manually correct it before proceeding.
!(Phone Number): If you enter a phone number obtained according to the scenario, special content will be displayed. This is only used in Prologue 1. (Example input: !0312345678)

Due to many custom systems, normal operation cannot be guaranteed on low-end models.
