How NOT to Summon an OVERLORD

Suzuki Satoru was a max level player in the DMMORPG YGGDRASIL. One day, as the final moments of the game draw to a close, he gets summoned into another world as his avatar, Momonga, and meets two girls who both insist that they're the one who summoned him.

They attempt to use an enslavement ritual and place Momonga under their control, but this activates his undead racial skill, [Mental Immunity]. Both girls are forced under the effects of their own spell due to the magic expanding over a radius, and now must serve the undead until the spell can be undone.

Thus begins the adventures of a powerful Overlord (roleplayer) who tries to find his place in the world, and destroy potential enemies with his immense power and YGGDRASIL hax.
