Rin Itami

Is an unknown girl Areshi met when he left the Precipice of the Abyss in the Blackwood forest. Since then she has been traveling with Areshi. So far nothing is known about her background or power.

Even her name, Rin Itami, is a name Areshi made for her because she had none when he asked her about her name. For reference, Rin means cold.
