A seven-year-old boy who is already attending middle school as a skipped-grade student. He has Asperger's Syndrome — innate, causing him to dislike socializing and struggle making friends, though his language function remains intact. He is extremely handsome with delicate features, deep cool eyes, and wears a dainty bowtie, resembling a proud little aristocrat from British dramas. He is quiet and reserved, preferring reading and research. He achieved perfect scores across the board in his first exam after transferring. Einstein is his most admired physicist. He accepts You You's friendship seriously.
