Shiawase★Mille-Feuille ~Sora kara Futago ga Futtekita!!~

In a small village not far away from the big city... On the outskirts of said village, surrounded by sea and forest, there lives a single artist. His name is Masaru. He draws under the penname Kasugano Shougo. Even though he isn't the most famous of painters, his artistry is promising enough. He has withdrawn from the tumult in town to relax and lets time dictate his path – the path to become a professional artist. During one night, illuminated by beautiful moonlight, his life is about to change significantly. Initiated by a shooting star... no, a meteorite? While he's leisurely sipping on his teacup, suddenly an UFO comes crashing into his garden. Said UFO evidently must contain extraterrestrial visitors, but he's baffled when they turn out to be two twin sisters. Since the aliens would be entirely alone on earth and - to top it all off - they also look like toddlers, Masaru couldn't simply leave them to their fate and decides that he must assume the role as their foster parent. And so he does: Masaru starts living together with world's strangest alien twin sisters and puts effort into raising them from mischievous little children into the ideal girls.
