Shella

Shella is a prominent figure within the Demon Realm's moderate faction, best known as the mother of Maria Naruse and Lucia. She endured prolonged captivity at the hands of radical faction leader Zolgear, who used her as a hostage to pressure the moderates. The ordeal drained the majority of her demonic power, leaving her with a physical appearance that looks younger than her own daughters. In the BURST arc, Shella steps into the role of secretary to Acting Demon King Ramzas, skillfully managing administrative duties and providing crucial behind-the-scenes support to the protagonist's group—all while letting her unwavering maternal devotion shine through her calm and capable exterior.
