episode 5:

Okay, this episode felt like we're watching a Boku no Hero Academie-spinoff now. Wth. The suit even looks similar to Deku's shitty suit. I wonder if this hero shtick keeps going or not. Would be weird to go back from saving people, but next episode makes it sound like he's no longer doing hero stuff. Hm.

Also, this anime committed a cardinal sin that zombie movies mustn't do: Zombie animals.
Why do 99% of zombie movies avoid animal zombies being a thing - because humans would be utterly fucked then. Defending against human zombies is one problem. Defending against the entire animal kingdom is impossible. This time it was an aquarium shark and some fish, but it's guaranteed that there zombie fish in the ocean now, too. Plus surely there's zombie bird. And if zombie insects are a thing, game over.
The zombie shark was kinda cool, but you really are inviting a mess of plot holes to come.

At least development with strategy girl.

Kencho running around naked will never not be super weird, but I guess that's Japanese culture.
