Zeppy (ゼッピー, Zeppii) is a miniature white squid that often accompanies Schwer-Muta Casasola Merkle. Because of her distrust for other human beings, she regards Zeppy as her only friend. She refers to him endearingly as Mister Zeppy (ゼッピーさん, Zeppiisan).

Whenever Schwer-Muta is engaged in combat, Zeppy acts as her support by spraying ink at her opponents to blind them, and starting from ~Freudenstachel~ began using a physical attack where Schwer grabs onto his tentacles and flings his body forwards before returning to Schwer. Though he cannot speak, Zeppy communicates with others by making the sound "kwui-kwui". He is quite emotional and will often exhibit anger or annoyance whenever Schwer herself does not.


  • Zeppy's name (actually pronounced "Seppy") comes from the German "sepia" or the Italian "seppia", both of them meaning "squid".
  • Zeppy's name is also similar to the Zeppelin Family, suggesting a possible connection there.
