Doutei Yuusha no Harem Maou Toubatsuki

For the Subjugation of the Demon Lord, the hero Alvin was invited by the king. The first to join his party was the elven priestess, Rishel. As soon as they met, she invited him to the inn before the other companions joined... It seems there's another purpose besides defeating the Demon Lord!? To the somewhat shy and virgin hero... the priestess (elven girl), the warrior (beast girl), and the assassin (tan-skinned girl) are all coming on to him with their charms ♥
