Aroe

Aroe is a young girl whose hair is made of Aloe, which does not benefit her as she often requires water. Aroe does not often make direct contact with the other characters in the anime and her appearances are often a side story--although she encountered them at the final scene of the final episode.
Aroe's Aloe made hair, bursts many of her vinyl wading pools due to its sharpness. Aroe is often seen throughout the series in a dizzy state, sometimes due to needing water and on other occasions due to misfortune. Her birthday is on June 15.
