> Is this the most relatable anime of all time?
No, it is not. Picrel is!

I don't feel that I can relate to N・H・Kにようこそ! at all. Most of the situations are so extravagant and surreal. Dating a girl? Traveling to an island with a group of suiciders? Participating in a Comiket alike fair? Does anyone here have such an experience? I don't, that's for sure.

Sure my apartment is filled with garbage, I'm unemployed, and parents pay for my living. But what's the only things I can relate to. Other than that N・H・Kにようこそ! is at the same level of fiction as an isekai or harem title.
