Momo has been called "Yaomomo", like by Kyouka in chapter 114. I wanted to add that to her infobox, but I have no idea how it's written in Japanese. Is it kanji, katakana or hiragana? Juan D'Marco 20:01, December 10, 2016 (UTC)
It's just a nickname. That's not really put on infoboxes anymore (because they're not aliases). You could insert it into her intro, personality or trivia sections though. KingCannon (talk) 22:21, December 10, 2016 (UTC)
Unnamed mother (presumably) in Volume 8 Extra.
