This isn't a kid's manga... It even explicitly mentioned that it's aimed at adults...
Either way, I fucking hate this manga now. I was so happy that Runru finally came to life, only for that shit to be used for worthless gags. She doesn't even have a special friendship with Puniru now! Wasn't Runru's whole deal how much Puniru loved it/her?!?
Fuck this manga, and fuck this author.
