Tadashi Nakabayashi is a member of Miss Asaji’s class, and is regularly seen in the company of Taizou Aoyama and Yuuji Terayama. Tadashi and his pals had a lot of theories on the cause of the soccer field vandalism, suggesting the supernatural was to blame. Tadashi was later introduced to Guilmon prior to the battle with Sandiramon, and went on the school camping trip. Much later, when the D-Reaper threatened the world, Miss Asaji’s class shouted their support for Gallantmon, and though Tadashi was not explicitly shown, it stands to reason that he was present.
