Both Hitagi Senjyogahara and Koyomi Araragi from the anime 'Bakemonogatari' are becoming adorable little plushies to keep by your side! The plushies capture their most common expressions perfectly, and Hitagi even comes with a removable plushie stapler for her to hold!
There are also plans to make plushies of other Bakemonogatari characters, so watch out for them as well!
