Rotte no Omocha

Astarotte is a 10 year old succubus princess from a kingdom in a fantasy realm, separate from the human realm. Once a succubus reaches maturity, she must start gathering a male harem for herself in order to survive. The only problem is that Astarotte absolutely despises men! But her subordinates are pushing her to start choosing men to fill her harem needs. She chooses as her first harem candidate... a human boy!Edit: You can't really call him a 'boy', he has a daughter.
