[PreSage]

Haven't read the manga but I found the first episode to be interesting.

The only thing I felt didn't quite work was the sudden change in mood at the end from seriously sad when his last friend died to suddenly comedic - kind of ruined the sad moment with the abrupt change. It would have worked better if the ending continued with the darker mood.

Anyway, I'll watch a few more episodes until all the hack and slash bores me (unless the plot continues to be interesting).
