The first Magikano doujinshi I've ever seen! Thanks!
Please allow me to recommend the original comic Magikano(マジカノ) to you. It might be old, but you'll find it interesting. I can never understand its "ending".
This is one of a very few Magikano doujins I've seen. Too bad, because I find the Magikano Anime and Manga to be underrated, although I understand why they're both not considered classics, despite the manga having 52 chapters, and with long page counts.
The main heroine being so mediocre while also having an awful haircut really didn't help, along with the manga staff locking themselves in with her with the "fated mirror" destiny plotline while also refusing to change the girl's hairstyle, outfits, and slightly abrasive (and also kind of boring) personality.
Mamiya Ayumi easily gets lapped by the older 2 of the MC's sisters, her own younger sister, the MC's childhood friend, the witch hunter girl, and arguably her own "robot" assistant. She's easily in the bottom tier of her own manga despite supposedly being the top girl. One of the reasons Magikano hasn't aged well (aside from some weird chapters early on) is how bad of a heroine Ayumi is. Nowadays every shounen manga that requires attractive girl leads has a female MC (or a group of them) that leaves her in the dust.
Many of the other characters have aged better though, and we can see how some have even inspired tropes or copies of them given how far back this manga was made. (It's roughly 20 years old or so)
