Dragon's death battle

Sebas Tian(Overlord)

Sebas Tian is the leader of the elite group of warriors maids, Pleiades and is the head butler of the Great Tomb of Nazarick. Created by Touch Me, he shares the Supreme Being kind hearted nature, a stark contradiction to the outright depraved nature of some of the other denizens of the tomb.
