It never fails to amaze me how isekai protagonists just find hot springs.
Like just how fucking common are these things in Japan that they have the expectation of just running into them randomly in the wild?
And they have the nerve to go basing all their fantasy worlds on middle age European cultures decorated with purloined mythological references, then go sticking fucking rice, miso and onsens all over the fucking place.
Anyway, Sui is probably STILL going to become a loli. I've learnt never to trust anything apparently gendered in mango translation.
