依蕾奈·兀儿塞斯

第三卷登场人物，雷渥夫黑学园的学生。过去为了保护妹妹普莉熙拉不惜成为实验用的白老鼠，与【恶辣之王】狄路克·艾贝尔范签下契约必须为其工作。 因为实现愿望的代价欠狄路克大笔债务，透过服从命令还清，也会去学园都市欢乐街的地下赌场赌博赚钱，但赢钱的时候常与赌场的负责人起冲突，而输钱的时候有时也会一怒之下开始砸赌场，因此与众多赌场都有结怨，成为恶名昭彰的一名赌客。 个性暴虐但很有义气，欠下人情就一定要还清且不论立场。非常重视普莉熙拉，因为普莉熙拉被绫斗救过一次而与后者结下交情。 使用纯星煌式武装──霸溃血镰，拥有非比寻常的战斗力、但也同时受其影响让性格更加暴虐，称号为“吸血暴姬”。

简介来自 Bangumi

Irene is a student at Rewolf Black Institute and the older sister of Priscilla. She and her sister are from a war-torn country, and got saved by the student council president of Rewolf Black Institute, Dirk Eberwein, as an exchange for Irene becoming Gravisheath's owner. Irene is harsh, cynical, rude, and violent, which could be partially attributed to their harsh upbringing. As such, she irritates, and makes enemies easily out of, just about anyone around her. Priscilla seems to be the only one capable of telling her off, even capable of making her apologize to others for her misdeeds. Irene wields the Ogre Lux Gravisheath, which enables her to control gravity within a set area and create gravity orbs at the cost of her blood.
