This apparently got lost in the migration and I can’t find it on Mangadex or using Google. Things I vaguely remember about it:
1. MC was high school boy, vaguely yankee-ish appearance
2. He ends up with a supernatural familiar spirit who is a (female) oni with a club which is actually a lollipop
3. The romantic interest is a loner girl who is into music; her familiar is a 3-headed dog
4. There’s an organization (possibly the student council? I can’t remember) of students who have familiars who protect the school
5. The familiars are usually in little chibi form when not active, and IIRC pretend to be keychain dongles/phone straps
6. One of the early plot arcs involved a fish monster living in the mirrors of the school
7. The series got axed and wrapped up very quickly, and ended with the MC and the music girl very suddenly dating
