About the Game

Iris works as a Purifier, a person who helps souls of the deceased move on to the afterlife. Her fate changes after coming into contact with the Magicians, half-immortal beings who watch over the MO worlds. Interacting with them, the mystery of the MO worlds' origins will come to light.

Don't be deceived by the lighthearted parts--despite the fun fantasy setting, MO isn't a world that will let you survive with something as flimsy as "the power of friendship."

This is a story written to make you both laugh and cry. At the very least, it has a lot of puns and glasses jokes. This game has a 75% "made me cry" rate, according to the survey.

✦ Characters ✦



Iris: The heroine. A gentle, awkward, and surprisingly brave girl who tries her best.

Rieffe: Iris' kind but detached childhood friend who always worries about her.

Lanneis: A strict and sarcastic person who glares and pushes up his glasses way too often.

Reqieu: Used to be Iris' teacher. Serious, but gentle and low-key sarcastic.

Septem: A serious, kind, and dutiful boy who likes flowers. He's kind of shy once you talk to him. Always polite.



✦ Warnings: light/moderate blood, themes of death
✦ Standalone game but with references to the other Magical Otoge games (Ciel, Anholly)
✦ Stretch goal bonus routes added for free after purchase milestones (details in the Google Form after purchasing the game)

This game is a straightforward visual novel, so there's no walkthrough necessary. It will be very obvious when a choice will affect the ending. After clearing the game once, a guide will appear in the Extras that explains how to get the Good/Bad Ends.
