hakaba no aruji
A Banica Conchita look-alike who appears in Heartbeat Clocktower as the awakened Glass of Conchita and the new Master of the Graveyard. She reappears as a minor character in Twiright Prank and a major one in Chaban Capriccio.
Turns out to actually be Banica Conchita as the new demon of gluttony. She is utilized by Abyss I.R. during Aku no Musume to try and disrupt the legitimacy of the Lucifenian royal family, with the instruction being to possess the heir Alexiel Lucifen d'Autriche. However, because he offered her his snack, she instead decides to possess his twin sister Riliane. The resulting chaos ends with Riliane losing her memories after being exorcised and Alexiel leaving the royal family, instead being taken in by the swordsman Leonhart Avadonia as Allen Avadonia.
