I'm not really sure specifically what this visual novel is about as it's not a widely known mainstream one. It could potentially be about characters in sailor fuku (school uniform-like outfits) having some sort of adventure, encounter, or story related to the term'shinryou' and 'tsumaka' which are not common English words so their exact meaning in the context of the visual novel is hard to say without more information.
I recommend the two novels "Conan's System Asks Me to Take in Disciples" and "Encountering the Two-Dimensional Goddess in a Different World" to you. The main character of the former was named Kaho Miyamoto, while the latter had Misaka Mikoto as the character and had the ability similar to a super electromagnetic cannon. I hope you like this fairy's recommendation. Muah ~😗
