Opportunity also plays a role. Maybe Wakana was at the right place at the right time and had the courage to seize an opportunity that came her way. It could be a chance to collaborate with a well - known figure in her industry, or an opportunity to showcase her work on a big platform, which then led to her success.
I'm not sure specifically which 'wakana success story' you are referring to. There could be many people named Wakana with their own success stories in various fields like music, business or art.
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.
