i'm pretty sure that Giselle is a man...and his body (female body) are not his true body or vessel like Gremmy which his true vessel is his brain...so i think the only true vessel of Giselle is his BLOOD

Gremmy's true vessel = Brain (his body form only his imagination)

Gissele's true vessel = Blood (he's acquired female body with his blood)

that's why no matter how shinigami slash his body, he didn't die

and i'm pretty sure that Kirinji will be defeat because no matter how hot his hot spring water is, it can't beat the hottest of Yamamoto's Bankai which Juha held
