Schrödinger, a non-human entity allied with the Sefiro Fiore Nagataki Branch, assumes the form of a talking cat partnered with Laplace, a sentient crow. Together, they provide tactical counsel to branch leader Etia Visconti and oversee logistical operations in the organization’s fight against Daemonia. Their duties extend to coordinating with the Tendo homunculus sisters—Itsuki, Mutsumi, and Nanase—who conduct experimental research and operate a dimensional gateway to deploy Elemental Tarot users against threats. The homunculi collectively command the "Wheel of Fortune" arcana, while Schrödinger’s direct ties to this power remain undefined. Available records emphasize his operational role within the Nagataki Branch’s infrastructure, with no elaboration on his origins, personal history, or evolution across supplementary media narratives.
