What you should expect from both is obviously horror, although it also has some combat seeing that several heroines from the duology are demon hunter with the MC from Aoishiro is kendo club captain from all girl school. Oh yes, several heroines are also have supernatural ties.
Anyway, the duology is now available on Steam and Switch, so feel free to try it if you're interested with it. For Steam version, I should say that they did the good job with Aoishiro, in that they manage to translate the flowchart and dictionary on top compressed the size (No longer that people need to allocate 7 GB HDD to play Aoishiro, but instead only less than 3 GB). Unfortunately though, the publisher apparently only working with this on 1080p, so the game will be zoomed in if you play it with PC that has resolution less than 1080p (It's problematic in Akai Ito with you can't even view the face in the sprites). The issues aside, I hope that you'll have fun if you played this.
