He tried to save the fallen girls, but they came after him instead.

[A novel where the male lead takes on multiple female characters, and his strength is ultimately revealed later]
A neon-themed eroge game with no system; only a task list to save a fallen girl has been unlocked.
You can only get rewards by completing the tasks.
This includes basic daily necessities.
But after completing the mission, instead of leaving, they came to my door.
They want to drag me down in reverse.
The notorious female gang leader: I didn't say you could leave!
The neighbor's wife: Shirakawa-kun, I'll take good care of you!
The yandere girl from the video game club: Shirakawa belongs to me alone, and no one can stop me!
Contrasting Sisters: It's not impossible for the two of us to serve you together.
Sorry, I have to go now!
