Oh hi Dee, glad to see you back after Episode 9! But anyways, this is Alis’ hometown (or rather a replica of it) where his class are trapped in a time loop.
And BTW, nice school uniform Ai-chan!
Regardless, Alis and Dee are aware of the loop. Unfortunately for the rest of them, they don’t get a clue until it’s too late.
Heck, he killed his classmates only to revive again like it nothing happened. Wait, I felt that I’m watching Endless Eight all over again!
Anyways, on to the next episode. And I have a feeling that Dee is behind all of this. Oh, and the reason why she becomes a ghost will be revealed next week!
