a pain to even read, feels like the author had chuunibyou desire he put everything into this story.. the only redeeming feature is probably the nice art, but the story is... pretty bad.
It's just another avalanche of tropes from those past 5-10 years, add in a mix of fantasy and reality setting to try to make it different from the other stories, but it failed pretty hard because all the characters are 2D to the possible. They each have just 1 set of about 3 pros/cons and the story rolls with it making this a real pain to read. Just skip the dialogues and admire the fan-service to not lose a half-hour of your time (just 5 min for the fan-service ;D)
