Zeppy is a white miniature squid that often accompanies Schwer-Muta Casasola Merkle in the Rosenkreuzstilette series. Not only does he aid her in battle, but he also shows expressions whenever Schwer herself does not. Schwer regards him as her only friend due to her distrust of others for her troubled childhood. In battle, Zeppy supports his friend by spitting ink into the air, after which it rains back down. The ink can temporarily blind opponents for a few seconds.
