|Relationships||Schwer-Muta Casasola Merkle (friend, partner)|
- —Zeppy, Rosenkreuzstilette
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 comes from the word "Zeppelin". This is interesting, as the Sepperins' family name, like Zeppy's name, is also derived from Zeppelin. Therefore, it could be possible that Zeppy was named after the Sepperins.
