Astarotte`s Toy

"Astarotte's Toy" (アスタロッテのおもちゃ！), also known as "Rotte's Toy", is a Japanese manga series written and illustrated by Yui Haga. The story centers around Naoya Touhara, a man who is brought to a magical world to become a candidate for the harem of the succubus princess Astarotte Ygvar. Astarotte, a young succubus princess, has a strong dislike for men, but due to her race, she requires a substance called "life seed" from males to survive. Naoya's arrival disrupts her preconceived notions and leads to a series of humorous and heartwarming events. The manga began serialization in the July 2007 issue of Dengeki Maoh magazine and concluded in December 2013. In 2011, the manga was adapted into a 12-episode TV anime series produced by Diomedéa, which aired from April to June of that year. Additionally, there is an OVA special, "Astarotte no Omocha! EX," released in September 2011. The anime differs somewhat from the manga in terms of plot and characterization, such as the addition of a magical tattoo on Astarotte's back. The anime's overall tone is more sentimental.
