Mega Shota Demon Lord ♡ Master or Servant

A comedic adult game about a protagonist who is transported into a demon king's castle and ends up serving as the exclusive energy source for the demon lord's magic replenishment. After a maid discovers the protagonist's extraordinary magical reserves, he is forcibly employed by the demon king's army. The game progresses by completing requests from the castle's inhabitants and uncovering hidden H-scenes by meeting specific character conditions. Each day culminates in an intimate "magic replenishment" session with the demon king. Features two different endings and a playtime of roughly 1.5 hours per playthrough, with additional content unlocking through hidden elements and alternate ending collection.
