Art has gone downhill quite a bit with most characters having same face syndrome with different hairstyles or eyebrows. If you compare chapter 1 with recent chapters such as chapter 40 or 48, which both introduced new fights, you can see a vast difference with the first chapter having variation...
I’ve read right up to chapter 18 and the artist seems to have ‘same body syndrome’ and cannot draw any other female body aside from a loli. An ancient dragon, a vampire, two demon maids, hell even a hero has the body of a small girl. It’s very offputting and makes the whole thing not enjoyable...
Manga is pretty subpar. They had a good start with the MC and the main girl, but then introduced too many characters that felt extremely two dimensional. No character has a fully fleshed out personality, so that when they actually befriend Mashiro it doesn’t even feel like the same characters...
