Reiss Hell

Reiss Hell (レース ヘルス Reisu Herusu) is one of the primary antagonists to the series. She is part of a labeled terrorist organization known as Shin Sekai Yori, and is the former partner to Ophelia Silmarillion within the groups pairings. Reiss is one of the stronger members of the group, which is why Ophellia specifically wanted to be partnered with her, hoping she could lure her into a fight. Reiss had a very specific form of Lost Magic called Ergo Proxy and this ability is also what keeps Ophelia in check, waiting for an opportunity. She is also the one who put Shin in a coma.
