Mari, Ayuki

摩利あゆき

Ayuki is Tomari's closest female friend. Like Yasuna, she is quiet and reserved, though she appears to be more social than Yasuna. In fact, she serves as the voice of reason during the interactions of the other characters. Additionally, Ayuki seems interested in observing the people around her and enjoys learning about the sciences, particularly biological sciences.
It is indirectly suggested that Ayuki is also interested in Hazumu, and later in the anime, she seems to be interested in Tomari as well. However, she states that she prefers not to get involved in the developing love triangle and simply observes from the sidelines.
