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

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".
