I have one question for you:
I mean, there's maids who are twins.
A fuzzy cat spirit.
This adorable girl.
and don't forget best MC ever, Subaru!!!!
The show is funny, interesting, mysterious, and has a plot unlike things I've seen before.
You could, I guess, compare the time skipping aspect to ERASED and maybe even to Rokka no Yuusha, but it's seriously INTERESTING. There's even a few more characters worth loving!
Not many anime naturally break the 4th wall by having a unique MC who would be more like one of us viewers going into a fantasy world!! Seriously! It is extremely self-aware of all the tropes it's throwing around and is flat out laughing at them. The cliffhangers feel good unlike most shows, when you understand that going to a restore point is a part of the story progression it's really interesting.
I've read that the writer of the manga is up to more than 500 chapters & it doesn't fall off in terms of quality, which means I'll be watching this for QUITE a while!!!
