Harukasan

Harukasan is a puchidol who resembles Haruka Amami and made her debut in Puchim@s Episode 11: Madly in Love.

History
Iori Minase found Harukasan in a temple that looked like a shack while trying to get out of the rain. Harukasan then chomps on Iori's forehead. As Iori runs in the rain Harukasan chases after her and in the rain Harukasan begins to multiply exponentially.

Later in the series, Harukasan is shown to have alternate abilities than multiply when exposed to water: she either grows to titanic sizes, or shrinks to the size of an ant.

When her ribbons are misplaced, Harukasan takes on a dark demon like personality.
