Professor Petterson, with his lean yet fit build, stands by the poolside at the monastery, exuding a relaxed and joyful demeanor. His classic yellow polo shirt has been adapted into a swim-friendly version, paired with white swim trunks, a brown belt-style waistband, and casual blue pool shoes. His short, tightly curled hair is still neatly cut in a military style, and his goatee remains well-groomed, giving him a sharp yet approachable look. Beside him, his two students, dressed similarly in swim versions of their classic uniforms—navy blue swim trunks with yellow accents—are laughing and splashing in the pool. One of the boys has spiked black hair, and the other is blond with striking green eyes. The three of them are clearly enjoying the moment, their playful banter echoing across the serene monastery grounds. The scene is filled with light-hearted fun as they take a break from their usual routines to unwind and bond in the cool water under the afternoon sun.
