Nago

Nago (ナゴ) is a black, transmogrifying cat, and a pet familiar that always accompanies Rachel Alucard alongside Gii.

History
Nago is Rachel’s black, transmogrifying cat that speaks and acts just as snobbishly as her. He is often seen in umbrella form, but he can also morph into (and be used as) either a Lobelia (bat lance), a cannon, or a chair. It is possible that Nago is homosexual, due to his comments on Jin and Hakumen, such as “Just seeing a hot man in chains just makes me…” and saying that Jin is “just his type” much to Gii’s discomfort and in BlazBlue: Chronophantasma he states that Amane is “a cutie pie”. Like Gii, Nago’s true form is actually unknown.
