So should the demon climb the ranks of the demon army and gain abilities like once you are a captain you can summon one soldier from nowhere to fight for you and commander summons 2 general 3 and admiral 4 Lord 5 and they could get other abilities instead
Okay I think I will make an adaptive storyline so if you help the good guys as the demon you will be be a good guy but if you help the bad guys you will be bad guy
