I have to say that's an interesting take on the whole bullying victim summons a demon to grant them a wish. I think that my main gripe is how limited the facial expressions of the sprites were that it didn't match the dialogue and tone, as well as how similar both Ayaka and Emi were which threw me off at the beginning. Another thing I wanted to point out was the music at the beginning, it felt like it didn't fit much with the scenes like the bullying scene and seemed way to preppy. But I did enjoy myself at the latter stage of the story, finding it cute if not cliche.
I find it interesting how the dynamic between Ayaka and Emi played out because they are both cowardly yet brave, we see this most with how Ayaka treats Emi as she is harsh to Emi because Emi reminds her of herself as well as her own internalized feelings. I also find it interesting how Emi internalizes her feelings to Ayaka, I'm sure she noticed that the coins in her piggy bank weren't being depleted and caused her to be curious about Ayaka's true intentions.
Despite that, I think the visual novel is pretty well done in terms of visuals, I found the story a bit slow paced and at the same time a bit oddly placed with the new informations we glean from both Ayaka and Emi but it's pretty well done!
