freaking knew it..... ok so its safe to assume every "Great monsters" in this manga that fought againts the MC gonna turn into a girl and serve him .-.

I think it stops at just Tomoe and Mio. They later acquire more characters, or whole races, but none are as strong as those 2. Tomoe goes full Weaboo and tries to create her own Japan inside Asora by recruiting entire races to become its populace.
he isn't Saitama i guess... can't defeat an enemy that keeps regenerating with the power you use to try and defeat it.... and there it goes... +another waifu.... still he needs to get more attributes...
@izayamikaelis Not really. It's pretty much these 2 for the longest time. I get that most isekais end up being trashy harems but I think this series in particular makes it more interesting as they both act their part as proper retainers and help the MC further his goals instead of just tagging along as a pretty accessory.

She's obsessed with the Japanese culture, specifically samurai. That's why she wants black hair.
And she has blue hair, I believe. Or at least she does in the novel. Its because she's specifically water element. Mio is darkness, so she got black hair.
