A most useless episode:

Episode 15.5 - Derp


A recap with narration by Iris (in her most exceedingly insufferable voice). A few minutes of new material at most and that new material was completely inconsequential.

If this episode actually succeeded in anything, it's to verify Ryner being hard M. Nothing else would explain why he still sticks to the present company and puts up with all the inhumane treatment he's subjected to.
