Lotus Eaters has so many chapters now that I really can't recall which one he's talking about here... 🫤
Anyway, the specific name he uses for this Aya is 黒射 – which I would presume is pronounced "Kuroi" which would conventionally be "Black" too. The joke here is that this would at hindsight be "Kuro + Sha" as the second character is the "Sha" in Shameimaru – hence the translation Black Shameimaru.
