An RPG game where the student council president battles in a school where common sense has been altered.

She dismisses the lax petitions that arrive from students every day.
Many look upon her with envy as she strictly manages the student council.

At that moment, a mysterious voice echoes in Kisaki's mind…
Guided by the voice, Kisaki transforms into a "Demon Sealer" and deploys her "Demon Sealing Armor"!
She cuts down the rampaging student council president with a single stroke!!
Now a "Demon Sealer," Kisaki's battle to resolve the anomalies within the school, using the student council room as her base, begins now!
However, outside, a bizarre school with altered common sense awaits her…

There’s a rumor in this town that’s probably a kind of urban legend.
“Summer Cherry Blossom,” “Withered Cherry Blossom,” “Yokai Cherry Blossom”… people call it by different names, but the rumor originated from a strange phenomenon caused by an old cherry tree that couldn’t be explained by science.
They say… that cherry tree bloomed in full glory during the summer.
They say… but only for a very short time, just a few hours.
They say… a miracle happens to anyone lucky enough to see “its form.”
One afternoon after school, with summer vacation just around the corner, Tohru is approached by student council member Miyoshi, who suggests they go see the “old cherry tree” together.
Intrigued, Tohru readily agrees, and the two head to a grove of trees beside a park on their way home from school.
What they see there is… an old cherry tree in full bloom in the middle of summer.

The game features a play cycle of exploring and touching, where you explore in the morning and engage in intimate interactions in the afternoon. You can freely explore and interact with the girls in another world’s town, with the option to engage in intimate activities anywhere in town.

In the "links" section for ISExKAI MAIDEN - Osawari H as you like in another world, there are no links, just the statement "Switch the game language by editing Setting.ini file in the game folder" which I sincerely doubt was what you meant to put there.
