Udedango

Udedango (腕団子) is a rapidly rolling ayakashi that seems to be nothing more than a mass of arms, and any objects it has pulled into its body.

Appearance
Udedango seems to chiefly be a mass of mass of large arms, as well as various objects it has added to its body.

Plot
Udedango appears at Karasumori while Yoshimori is trying to perfect his zekkai, which is still limited to a flame-like aura around his body. Though Yoshimori manages to activate his zekkai successfully, Udedango's mass knocks him out of the way without even slowing down. Tokine, however, easily stops Udedango by spearing through its body from above with a kekkai.

Power & Abilities
Continuously Building Mass: As it rolls, Udedango's arms grab anything within reach to add to its own mass.

High Speed Rolling: It rolls at very high speed, and tends to bowl over or knock aside anything in its way.
