Tetsu Shinjō, a member of Team Asteroid in Cardfight!! Vanguard, possesses long purple hair and expresses a dislike for women. His actions directly prevented Kamui Katsuragi from achieving his dream of becoming a champion, creating significant conflict between them. Shinjō's approach toward Emi Sendo further contributed to Kamui's animosity. During the second season, Shinjō was part of New AL4 until Toshiki Kai temporarily replaced him on the team.
