Ayaka Nozawa
A young girl who comes running to the White Dragon looking for help after witnessing the murder of her family and neighbors over a drug dispute (although she herself is unaware of the reason). She earns Tatsuto's protection, then surprises him with her one strong talent: her cooking ability! Then it turns out that, after living for years on tasteless microwavable dinners and vitamin supplements, he finds himself unable to digest anything not made by Ayako, leading to Ayako's permanent residence in Tatsuto's apartment (and subsequent accompaniment on future missions).
