Haru

ハル

Haru has blonde hair, purple eyes, and long eyelashes, and is very cheerful and charismatic. He arrived as a transfer student alongside Yuki, introducing himself as an alien. People assume this is a joke because of his enthusiastic behavior, although there are some hints that may prove it true. He is seen carrying a fish in a bowl on his head, which refers to Haru as "brother." When upset by people's actions, he shoots them with a bright green water pistol, allowing him to briefly control their movements. Haru and his sister are on a secret mission on Earth to save it, and for some reason, they need Yuki to learn to fish in order to accomplish it. He is able to communicate telepathically with his sister via water.
