Prior to the events of the story, Kanonno lived with her parents and Rocks. Kanonno's parents were doctors and both died in the battlefield when she was a child, leaving her in the care of Rocks. Some time afterward, she joined Ad Libitum and since then has been traveling with the guild. At the same time, she started to like drawing sketches of unfamiliar landscapes and people that she herself did not understand, which would later play an important role in the game's story.
One day, after finishing a quest, Kanonno notices a floating light and follows after it. When the light finally stops, she is surprised to find a person, the Protagonist, surrounded by the light. When the Protagonist regains consciousness, Kanonno suggests for them to leave the area since it is dangerous. On their way to the Van Eltia, the Protagonist reveals that they do not remember anything but their own name.
At the Van Eltia, Kanonno introduces the Protagonist to the guild master, Ange Serena, who allows the Protagonist to stay at the Van Eltia until they regain their memories, under the condition that they must work as a guild member. Under Ange's order, Kanonno guides the Protagonist around the ship and introduces them to the other guild members. Afterward, Kanonno does not appear in the story often until Celsius joins the crew and Kanonno shows her the sketches of places she has drawn. Recognizing one of the sketches as an ancient temple that may hold a connection with the recent incidents and Lazaris, Rita Mordio copies Kanonno's document to find the location of the temple. The copying of her document causes Kanonno to become exhausted and lose consciousness, leaving her bedridden for a while.
Judith then confronts Kanonno regarding her drawings and considers the possibility that Kanonno may have a power to see the past through her document subconsciously, but Kanonno herself does not understand. Wanting to know about the meaning of her drawings, she asks the Protagonist to accompany her to meet Niata.
