In a small village, there is a legend about a person born from a sakura tree one thousand years ago. Though she appeared human in form, she could not understand love, and was therefore cruel. She was eventually destroyed. Now, the mythical Sakura tree is going to attempt to create human life once again. This time it is up to two high school students, the incredibly beautiful Tasuku and the love-allergic girl Honomi, to teach the Sakura Child about love.

Saiki Takaya, a guy who is easily misunderstood, one day finds a flask containing the succubus Lilim. She is very attractive but, she also has the tendency to drain the life force out of people.

From then, Lilim is accepted by Takaya's parents as a live-in girlfriend of sorts, and Takaya's heart seems to start wavering towards this voluptuous devil.
