Two demons escaped from Muzan's control. An ally or a threat?
Kanzaburou and tomioka demon form 😈. I inspired the design in your version of her demon form and basing/referencing it to some of giyuu's outfit somewhere on one of the official art of demon slayer.
And Kanzaburou's demon form. Long hair+Black wings+ and inspired powers from Hawks (MHA). Even becoming demon he still respect women.
"I will always be by your side Tomioka-sama no matter what..."
Overblot! Tomioka.
Her design is heavily inspired from mlbb Freya's skin (Raven Shogun). I don't know which one would fit her overblot name so you decide AlmightyDab
"Raven Shogun" or "Neptunian Shogun" (Neptunian means, relating to the Roman sea god Neptune or to the sea.)
English is not my first language. 😅
