Pierre

"If only... I hadn't left you alone! If only I hadn't gone back to the car to get my stuff, leaving you beside the lake!"

- Noguchi about her son

Pierre (ピエール) is a tertiary character featured in the one-shot Rohan at the Louvre. He is the son of Noguchi who drowns in a lake when she momentarily leaves him by himself. Pierre briefly reunites with his mother as a ghost conjured by her memories from the curse of the "Under the Moon" painting in the Louvre museum.

Appearance
Pierre is a young child with a dark hairstyle. He wears a long sleeve shirt and shorts, along with pants underneath the shorts.

As a ghost, he has a sad looking face with droopy eyes.

Personality
Nothing is known of Pierre's personality from when he was alive. However, as a "ghost" summoned by the Under the Moon painting, he momentarily looks happy to reunite with his mother.

Background
While Pierre and Noguchi were at a park one day, Noguchi had to retrieve things from her car so she momentarily left Pierre alone close to a lake. In the meantime, he had fallen in the lake and drowned. After finding his body, she only blames herself for causing his death.

Rohan at the Louvre
A ghost-like creature based on Pierre from Noguchi's memories emerges from Nizaemon Yamamura's "Under the Moon" painting when she approaches it in the Louvre museum. As he walks closer toward his mother, she breaks down and apologizes to him, feeling guilty for his death. Rohan Kishibe's pleas for Noguchi to get away from the ghost are in vain, as touching Pierre causes her body to inflate with water. Her body quickly bursts from the water, due to the curse of the painting making her experience drowning like how her son died. Even in her last moments, she is grateful to see her son for one last time.
