A show carried by its main characters and the fun conceit - what if your best friend was the cutest girl in the world? It's a little awkward at times but is mostly very charming, especially due to the acting of the two main characters (I watched in English). Fun fact, Tachibana is voiced by a romantic couple which I think has only happened before in Pop Team Epic. It's a fun friendship/romance/???? angle that you don't see much in standard anime!
This is only my second Isekai and it is not a genre I care about typically - that is still the case here. The most dull parts of this show are the weird RPG elements that make no sense given they weren't sucked into a game or something, the literal NPCs having no personality, and the played-out fantasyland world. Extremely shoehorned and would be better without them imo! If it's supposed to be a parody then it should maybe have those elements be actually humorous!
Animation was fun enough, though I didn't care for the songs in the OP or ED.
Worth a watch for the interesting main characters & fun central idea, but the rest is pretty mediocre!
