I have absolutely no idea what happened in this episode.
So the girl named Null tried to resurrect her dead sister? Or something? And wound up building this fluffy…. transforming…. robot…. thing? Wild.
Null and Peta (that’s pronounced with a short e) is a short comedy anime about a girl genius and her sister. I think. Its only five minutes long, and seems fairly charming, so consider checking it out for yourself.
