Lol, Iīm glad everybody can agree that the train lady randomly stripping off her clothes was exactly that: random
And I agree, "a step in the right direction".
The chase scene felt intense, the way this giant swarm kabane kept running after the train had something truly creepy to it, a feeling this series had been lacking compared to Attack on Titan. Whatīs missing now are proper ways of fighting kabane and proper ways of introducing more dangerous kabane (that arenīt relying on shitty human-shaped swarms, really, thatīs indefensibly stupid), as well as having a good mystery to it all.
One scene I really disliked, though: When Mumei looked at all the Kabane that Ikoma had slain and said "how is that possible, when weīre so weak?". Bullshit. Mumei would have killed all of these kabane with ease, had she not been trapped under a rock.
