Introduction Arc Edit
When Nozomi Kaminashi got an offer from a college with the best gymnastic programs, he told Nozomi to reconsider before decline that offer. He then warned Nozomi after learning that she wanted to try Keijo. The next day, he brought Nozomi and her friend, Taichi Omotenishi to the Nishinomiya Keijo Stadium to watch Keijo matches directly. He then advised Nozomi that it's up to her, and warned her once more that there are number of deaths of Keijo players. When Taichi disagreed with Nozomi, Kobayashi brought them to do a trial match. He eventually was impressed after Nozomi won the trial match. A few moments later, he was seen participating in gambling and won the bet.
