Because of this he thought nobody cared about him until he joined the football club. Shin is considered reticent and unapproachable by other people. He is neither prideful nor humble, always taking in things objectively and even if it's at the expense of offending someone else. Whenever their team loses or when he felt he has played poorly, he inflicts self-punishment on himself by doing even more rigorous training. Even then, Shin uses the hoarding on the restaurant, which is a model of a bull's head (horns and all) to exercise on, by doing one-handed chin-ups. While the Deimon Devil Bats are celebrating their first victory in the Fall Tournament, they meet up with the White Knights part-way at a buffet restaurant. Shin's mind is constantly on his physical conditioning. He's very good at analyzing a person's moves and how to react accordingly to stop him. It was through this experience that Shin was driven to improve on his running as well as his strength. This is because Sena is able to achieve the legendary Speed Of Light pace (40 yards in 4.2 seconds), and was the one person who actually beat him and his Spear Tackle outright with pure speed (no cuts-moves, etc.). He does consider Eyeshield 21 as a formidable opponent, as he admitted during the interview before the Kanto Elimination Rounds. He is one of the few characters who figured out that Sena was Eyeshield 21 right away. His signature move is the Spear Tackle, a powerful one-arm thrust that can stop any opponent, and later, agonizing players so much that they refuse to touch the ball ever again. Shin is considered the strongest and fastest linebacker in the history of Japan. Yusuke Murata, the series' artist, described that Shin is 'modeled after Bruce Lee and is a cool, handsome character.' Shin is noted by Sena to loosely Kenshiro from Fist of the North Star, which is used humorously in the manga to show Sena's fear of Shin. He is usually seen in a uniform or jersey, and times outside of school, he usually wears a sweatshirt and sweatpants. He has a very muscular build and sharp, stern facial features. Shin is a young Japanese man of above-average height with darkbrown eyes, short black hair, thick eyebrows, and a lightly tanned complexion. He is the most prominent rival of the series main character, Sena, alongside Patrick 'Panther' Spencer. Later on in the series, he also plays offense as a fullback. He is known for his strength, speed, and his famous Spear Tackle and was considered the strongest linebacker in Japan. Seijuro Shin (進清十郎, Shin Seijūrō) is the linebacker and ace of the Ojo White Knights. 4.2 seconds (after Tokyo Fall Tournament)
