Seijuro Shin

The fastest person lineback in the team. A silent person and doesn't talk much. Best friends with Sakuraba Haruto and Otawara. After the coach sees his talent, he decides to make him join and pass the training. Now even AFL wants him to join after he finishes his school because of his speed and a famous technique called 'Spear Tackle'. Not even Sena's speed can wthstand it's power. But his differ between his and Sena's dash is 0.4 seconds. After knowing his secret identity, he tells him he'll be waiting for him in the finals. Newspapeers mention that he's the best linebacker in Japan.
• 40-yard-dash: From vol. 3, it was 4. 37 seconds
• Position: Lineback
• Jersy: 44
• He's a moron in technology. Once the coach gives him a GPRS as a map so he won't get lost in the forest near Mount Fuji for practice. Yet in the middle of the practise, he assume the map's insid the GPRS and breaks it.
• Works almost as hard as Yukimistu everyday but more serious training.
