Tot Musica

Summoned in its First Movement, Tot Musica looms as a half-bodied giant with shaggy yellow hair, a stubby beard, and a chalk-white, fanged face fixed in a leering grin. One eye is a black void, the other a burning red cross, while its arms stretch out like rows of piano keys. A wide top hat crowns it, a dark cloak shrouds it, and flaming skulls ring its neck.

Its Second Movement keeps those features but grows bigger, swapping in green hair, clawed fingers, jagged teeth, and a crocodile-shaped hat. Once it drinks deeper from Uta's power and swallows her into itself, the Third Movement emerges as something far stranger: the cloak gone, a pudding-like lower half formed, an extra set of arms, feathered wings spread wide, and a jewel-studded crown bearing golden crocodiles. By then its grin has soured into a permanent scowl.

As a pure engine of ruin, Tot Musica barely registers as a thinking being and shows almost no mind of its own. Even so, it actively hunts down those who carry the Uta Uta no Mi, working to bend them toward singing the song that frees it.

The creature is staggeringly destructive, leveling Elegia during only a brief summoning by Uta. By possessing its host it appears at once inside the Uta World and across the real world, where it shrugs off every attack and looses dark crimson beams capable of flattening a city or sinking a Marine vessel. Its presence also bleeds the host's powers into reality, letting Uta raise Musical Note Soldiers, sprout dark wings, and conjure a swelling musical dome that drifts people skyward as it tries to fuse both worlds into one.

Defeating it demands simultaneous, precisely aimed strikes launched from the Uta World and the real world together. Like the Uta World itself, it seals away again the moment the fruit user falls asleep. Even dormant, the demon stays bound to fruit holders, its sheet music drifting up out of Elegia's ruins on its own to find Uta.
