Started watching this today/tonight, watched whole S1.
I have no idea how I hadn't heard of this, only reason I found it was because I was looking to download new episode for Gachiakura and the name was so silly I was just going to watch it for luls. Now starting S2 and I really really liked it. Got some fun OP char that is enough 'tism to make his badassery fun, got some feels, and got some fan service but surprisingly not that lewd.
I was ready to drop all the OP isekai etc. stuff because of Solo Leveling that I was told to be best OP mc animes and I disliked it. Well happy accidents happen I guess.
(Also Sylpha existing for my warrior maid needs is always nice).
I'm just happy to find new fun stuff. Is OG LN/Manga/whateveroriginalwas worth a read?
