Manga XXX - Zoku Koihime Episode 1

Musashi had returned to his village for a second time. They were four princesses that he'd known as children; he'd also forgotten about their sexual encounters. A familiarity with the hamlet and his grandmother's residence helped him recover some of his memories. He was greeted by his grandma and Tamamo, a girl he had never met before. Despite her claims, he had no memory of her whatsoever. Tamamo and he did things at night because of a weird odour. In reality, this was only the beginning of a conspiracy to avenge the village chief by employing Musashi as a pawn.
