Torara

Torara is a Marimo ghost and the guardian ghost of Usui Pirika.

About
Torara is a Marimo, called "Torasanpe" in the Ainu language, which means "Lake Faries". He is Pirika's guardian ghost, and has the ability to manipulate water. He has been Pirika's guardian ghost ever since he saved her from drowning in a lake when she was really young. However he is very shy, even more so than Kororo, and has a fear of strangers. This is why, although Pirika has the skills of a shaman, Torara has never made an appearence within the story.

Anime/Manga Difference
Torara is never shown in either the anime or the manga.
