Inferior demons are deformed creatures. They possessed heads that were swollen, their left arms were unnaturally thin, their massive right arms were made of several tentacles twined together, and their legs were of different lengths. The demons did not possess anything to tell their gender apart, and yellow pus oozed from countless small holes all over their bodies.
Inferior demons are level 10 demons that were made for destruction and slaughter. Unlike normal summons they do not follow the commands of the summoner instead, they attacked everything around them.
- These demons can be summoned using the 10th tier spell, 'Armageddon - Evil'.
- Suzuki Satoru summoned these demons to fight against the Elder Coffin Dragon Lord.
