Bu Oyun Hakkında

A Touhou Project fan-made STG, also a collab game with Vtuber Syrena.
There is only one stage in this game, and its length is about the same as Touhou Ex Stages. But there are four difficulties you can choose from.


Some day a random suspicious pink UFO showed up in Gensokyo.
This must be an incident!
Therefore Reimu and Marisa jumped in directly to attack the UFO, without knowing the fact that the owner of the UFO was Sirena, just an alien passing by.
Since the UFO was damaged, there is no more to say. With that, a spell card duel has begun.


Recreated UFO system from Touhou Undefined Fantastic Object, but there is only one type of color for the UFOs. You won't collect the wrong UFO by mistake again!
