Sei Yariman Sisters Pakopako Nikki The Animation

Synopsis

Based on the adult game by Orcsoft Team Goblin. After five years away, Kenta returns to his former home. His uncle's family now lives there, and he plans to stay there again since he will be attending the nearby school. This means he will see his older cousins—the twins Saki and Maki—once more; they used to look after him when he was younger. However, he is surprised to find that Saki and Maki have grown into very outgoing young women. Kenta quickly learns that his uncle has been transferred to another city, so only the three of them remain in the house. Saki and Maki waste no time in approaching him very aggressively.
