Seira

What defines a "Sekai-kei"? Perhaps it's 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 the 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.
It is set to end within one week regardless. While it can be bypassed, it's not recommended as it may 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 the 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 the second playthrough only. Since the second prologue assumes you have completed the first playthrough, it may be confusing if you play without knowing the settings.

🔋: The system will function normally only if there is a status window. If it is missing, include the corresponding icon in the input to restore it. If there is incorrect information in the status window, it is recommended to manually correct it before proceeding.
!(Phone Number): Depending on the progression, entering the obtained phone number will output special content. This is only used in Prologue 1. (Example input: !0312345678)

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