This came bit remind me with Demon Roots in story plot, there a progress and set back which reasonable, also sub story that enrich the game plot variant.
The art is above average, no white lightning in the hair, color and texture of character is great (izayoi's minion doll in battle is cutteeee ). Character design quite unique (Arisa, benevolent demon-queen. Ringo, lewd track runner). I love it. The setting of dungeon or place is well choice scenery, picture that peacefull and beautiful even using default rpgm tileset.
Sound, I might said average but well placed and not too overenergetic while still memorable. This BGM make me enjoy adventure with vibe slice-of-life of extraordinary antihero after school, rather bloodrush to kill demonlord and everything. Heal my scrambled school days, *hiks*.
UI, simple and ease to get used, default RPGM. Battle is not too much difficult, this game focusing on your completing story rather than grinding (but not too predetermine).
H-content, no animated no voiced (no suprise thou) but compesanted with good dark theme such anal toture, bdsm, cheating, prostitution, pregnancy, sex slave training, but lack of humiliation and exhibistsm. Cute character do dark lewd.
I give 5, because story, art, sound and H-content.
