Props to Sato. Even if he didn't call out the perv he didn't just let the guy keep doing what he was doing. Would've been good too if he at least removed some cameras from his "sister's" house like the ones in the bathroom and bedroom.
Great story overall. I was feeling tense about Mueller having bad intentions approaching Speranza (probably cause she was still a little girl), but I'm glad it was a (relatively) happy ending.
I'm interested to see where this goes, it's not often we get shonen protags who are morally dubious (they're still committing crimes at the end of the day). Like people have already said, this seems more about colonialism than immigration in general. Clear indicator is that immigrants aren't...
Ah okay so that's what lead into the attack on Mizuki. When I first started reading years ago, I was under the impression that Mako sort of set Mizuki up but didn't expect things to escalate. Good to know she wouldn't do that to a friend.
