Oh my gosh. Just when I thought this manga couldn't get any better, the mangaka presents a complex character development for the antagonist, who may or may not willingly take part in the main story, considering that he's not going to be the one to invade Earlshade kingdom (forgot the name, I think that's that)
Also, lemme make this quote.
"This manga is so good you can even remember the MC's name despite being isekai."
