So I think we can all agree that Koguma has been pretty impressive in her short career so far. She's already won a singles title betaing a pretty big name in Io , so it seems like Stardom is really high on her
Honestly the only thing I can see really stopping her from climbing up the ranks is if she gets injured or if she decided to retire early to go to college like Yuhi.
Speaking of Yuhi I actually find Koguma to be more impressive than Yuhi was. While Yuhi was more athletic Koguma is much smoother at selling and bumping for moves , and is also better at displaying emotion and selling the story of a match.
I also like that Stardom has already found a generational rival for her in Hazuki.
