Press Kit Here

This game contains themes such as: murder, suicide, bullying, and heavy language. Also maths. I know some of you are turned off by that. Understandable.


Yuki Kourei enrolls into Shigo Private High School, between the mountains of Hokkaido, to start life anew far from his hyper-protective mother.

His plan goes awry when he discovers the school's rigid hierarchies, in which the younger students must follow all of their upperclassmen's orders; too nervous to join them, he's completely cut off from the others and branded as Ghost.

Akito Ikeda, a fellow Ghost, persuades him to join the Spectral Brigade: a group of first-years who want to overthrow the current system. But nightmares and visions of someone dying haunt Yuki, and when a snowstorm cuts him and his schoolmates off from the outside world, these visions come true.

Yuki will have to win the trust of his schoolmates, discover who's trying to kill them, and why...

Just played through the demo--in a couple of sittings, though, due to time constraints. I was nervous going in because of the trigger warnings, since I am terrible with anything even mildly scary, but the demo was a delight and it didn't give me any issues, thankfully. I love the characters, the premise is very interesting, and I'm definitely looking forward to more! Great job!!


Thank you so much!! If you survived the demo most of the full game should be fine, I think! Just some graphic descriptions you can skim over when it gets too overwhelming (and you know they're there when the scary music hits). Please look forward to the rest! ☺️

I'm eager to check out the final release! Keep up the great work, and best of luck with development!

Is it still going?

Of course! Script is completed, currently putting sprites in the last chapter :) hopefully will be ready by the beginning of 2023, but I don't want to jinx it...


Design dei personaggi e soundtrack sono deliziosi, ho apprezzato le opzioni di accessibilità disponibili, e le informazioni relative al gioco come profili e glossario.Non vedo l'ora di poter vivere la storia completa! 

Grazie mille! <3
