Oh my, that was great! Seems like we're getting into our new arc, but first, lemme just say:
1. I love Semiu, damn! From the design, through what we know about her personality, up to the way she fights. Looks like her Jinki lets her see the trajectory of movements, thus acting as she "knows the future". It's great to combine some combat prowess with such a power. Suits it very well.
2. Logically, it would've seem like Vandals spread the word of Rudo's descent, but hey, maybe that's a red herring. If it's indeed them, maybe this small, funny group is just a beginning OR maybe it was to check their base's defenses without revealing their own hand (Vandal's I mean). Unless, of course, it's a prelude to some bigger action.
3. The leader looks cool AF. Intimidating design is what I want from my villains most of the time - or at least a cool one. This dude looks like he means business, so you expect him to. I wonder what's the plan. Something tells me that first he'd just like to isolate Rudo and talk to him 1-on-1. I don't really feel much malice from the Leader. More like "if I gotta kill you to comply, I will".
