-Mc is a necromancer and is desperately trying to level up ,but due to his powers he's kinda weak, after getting trapped in a dungeon he accidentally summons the deceased powerful leader of a powerful guild, (he might be a bit cuckoo and possessive due to the necromancer powers-)(but honestly all of the members of his guild are gonna become yanderes for the necromancer so who cares LOL)
