Anime body pillow

The anime body pillow is an ancient artifact that is said to give the person who possesses it unimaginable power (if he's worthy).

Origin
The anime body pillow was created when Diavolo was baking brownies. The recipe said to add 2 eggs, vinegar, water, brownie mix, and then to mix it before putting it in the oven for exactly 20 minutes. Instead of listening to the instructions, Diavolo decided to be a rebel against the system and put it in for 21 minutes instead.

This extra minute caused space and time to become warped beyond all belief as no one had ever put brownies in the oven for 1 extra minute up until now and thus, the anime dakimakura had been created.

How to be worthy
In order to be worthy of wielding the dakimakura in combat you must meet these specifications, otherwise the anime body pillow will tickle your armpits until you're begging for mercy but it will not show you mercy because you don't deserve it.
