Noguchi is a character from the one-shot Rohan at the Louvre.
Noguchi is a polite person, seeing the way she treated Rohan. Her past made her suffer greatly for all her life, as she was responsable for the death of her own son. After witnessing his ghost, she breaks down and loses all sense of danger.
Noguchi was the mother of Pierre. One day she left him alone for a moment close to a lakeshore in a park to take her things out of the car, but in the meantime he had fallen in the pond and drowned. When she came back to see his body she put all the blame of his death on herself.
Noguchi is introduced as the interpreter in charge of Japanese translations at the Louvre. She inquiries Rohan about his visit to the museum and finds through the archives that the painting he's searching for, "Under the Moon", is in stock in a abandoned warehouse called Z-13. Rohan asks to see it, but is only given permission if accompanied by her, Gaucher and two firefighters.
When the group finally finds the painting they start to die one after the other after recognizing someone in the dark. It turns out that the painting was making ghosts out of their memories and killing the group the same way these ghosts died. Noguchi tries to run, but is surrounded on all sides and sees the ghost of Pierre. She breaks down and apologizes to her son, emotionally unstable. Rohan's pleas for her to get away from the ghosts are in vain, as Pierre inflates her body with water, popping her. Even in her last moments, she is grateful to see her beloved son for one last time. Her body was never found and she was considered since then as missing.
