episode 6:

Phew, not a sad episode for once - but an unexpectedly action-heavy one! That fight against the "entity" was nicely animated, I especially loved how Fushi ran around as Marchi.

Also, I didn't expect Fushi's origin/existence to become part of the ongoing plot that early. I assumed he'd experience all sorts of adventures and in the last episode we find out where it all lead to. but nah, there is his creator This should make the story much more involved than I expected, very nice surprise.
