7 Senchi!愛情超迷你; 7 Centi!; 7 Centimeters!; 7センチ！; โลกอีกใบไซส์ 7 Cent! (Thai)

From Shoujo Crusade: One day, while in search for more food, our heroine stumbles upon a jar of what looked like umeboshi; little did she know that it would bring her more than just a full stomach. The mysterious snack somehow makes her shrink and she can only grow back when she eats something (which is a bit of a chore if you're THAT tiny). And if that's not troublesome enough, she's also dealing with her crush who seems to like her best friend!?
