Ashieru (Japanese アシエル) is the eldest son of a research group within Mezeporta Square.
Ashieru is known for his muffled speaking, making him hard to understand to many people. When he isn't wearing his glasses, some researchers say that it is hard to really say what he is thinking.
Ashieru is the lead researcher of his family's caravan for helping increase development within Mezeporta. He is known to constantly work for hours on end, or even days at a time, with his research. He works together in this caravan with his two siblings, Kieru and Oriōru.
He wears google-like glasses, a large head piece that resembles an air balloon, clothing that symbolizes his caravan, and has a beard, along with a mustache.
