Official site. Anime’s subtitle is Crazy Shrine Maidens…count me in!

Story summary pinched from God knows where:
“Our unlucky protagonist, Jin, uses the trunk of a sacred tree to carve a statue for a school project. When he takes it outside, to his surprise it begins absorbing the surrounding earth and transforms into, hold your breath on this one, a girl! So like all similar setups this guardian deity is pretty pissed that her tree was cut down and lives with Jin while she takes out her anger on squashing bugs….er, cleaning the “Impurities”.”

/Crazy Tomatsu Haruka fan here is melting with excitement. Also because Hanazawa Kana is in it, and she gets to continue her yuri-lovefest, staring at Tomatsu’s beautiful legs and dreaming of her wearing a bikini on a beach…I’ll elaborate on that someday.
