Toge Inumaki is important too. His special cursed speech ability makes him stand out. Also, the principal of the school, Masamichi Yaga, is likely to be important as he is in a position of authority and has an influence on Gojo and the other students. There could be other characters like the members of different clans that also play roles in the complex web of the story.
The story of the Antarctic expedition has brought us some enlightenment and insight. First of all, the Antarctic expedition demonstrated the courage and perseverance of mankind. Both Scott and Amundsen were faced with extreme environments and difficult conditions, but they still chose to challenge themselves and move forward bravely. This inspires us to persevere in the face of difficulties and challenges. Secondly, the Antarctic expedition also taught us the importance of teamwork. Both Team Scott and Team Amundsen were made up of groups of people who needed to support and cooperate with each other to complete their tasks. This reminds us that teamwork is the key to success in work and life. In addition, the Antarctic expedition also taught us caution and planning. Team Scott's failure was partly due to their flawed plans, which did not take the changing environment into account.
It's hard to pinpoint exactly where Gojo is at any given time in the manga. His whereabouts change as the story progresses and different scenarios unfold. It could be in a supernatural realm, a mission site, or interacting with other characters.
