Student and fantasy creature in Japanese restroom AI Image Prompt

Create a square, candid documentary-style photo inside a cramped old Japanese restroom with worn beige walls, a narrow doorway framing the scene, and small green-blue square floor tiles. Show exactly 2 subjects: 1 teenage Japanese schoolgirl wearing a {argument name="school uniform" default="navy sailor uniform with white collar stripes, red bow, white socks, and black loafers"}, sitting on a white toilet with her knees together and head bowed in embarrassment, her face deliberately obscured by a soft rectangular privacy blur; and 1 small uncanny fantasy creature standing to her right, about child-height, with dusty pink fuzzy skin, a round body, tiny horns or ear-like points, very large glossy black eyes, a small flat mouth, short arms, stubby legs, and a tail. The creature should be calmly offering exactly 1 roll of toilet paper with a loose sheet hanging down. On the wall behind them place exactly 1 vertical Japanese calligraphy poster with black brush text, including the quote {argument name="wall quote" default="叱ってくれる人を持つことは大きな幸福である 松下幸之助"}. Use muted colors, dim indoor lighting, slight film grain, realistic lens perspective, and an awkward humorous mood, like a strange found photograph from the early 2000s. Keep the composition intimate and vertical within a square crop, with the girl on the left, the creature on the right, the poster above the creature, and no extra characters or objects beyond restroom fixtures.
