The story was lackluster and you never really develop an interest in the story or the world of Trinity Seven.
The characters are all quite dull and perverted without much depth. You could say relationships are built upon between the characters, but in a harem sense more than anything.
My last hope was for the combat, but I would argue that the combat is even worse than the characters and the story. To put it like this the protagonist is weak physically, weak mentally and is relying on copying the power of other characters through his grimoire.
The story and characters are so bad and it's so riddled with ecchi that this show would have done much better if it had been turned into a hentai, honestly it could have been a pretty successful hentai in my opinion as well.
PS: The opening theme is good enough, but I don't recommend watching the show just based on the opening theme.
