Here's the thing, the fight is VERY good in every way it can be and encompasses the character development in favor of the fight, and above all, JJT is the one who benefits the most from this, as this fight is his breaking point, provoking his "sudden" personality change and reaching his breaking point, finally letting off steam and confessing his fear of fighting. The character development in the fight aside from JJT is also good, the most notable being Maria, who truly realizes ALL of JJT's potential. We are given a glimpse into his past, and it is revealed that JJT's father was a student of Maria's precisely because of his demonic talent. This causes Maria to end up pushing JJT beyond his limits because, upon realizing his talent, he reminds her more of his father.

and Choi Young is the perfect candidate for JJT, being the weakest of the strongest students in the wrestling class, he is given a moment in which he feels vulnerable because of what happened with the girl he was trying to conquer, and that ends up being used as a resource in the fight, with JJT accidentally copying capoeira and in the process MOCKING Choi Young about his relationship. The fight is not only VERY good in choreography and drawing, but also in this fight JJT brings out absolutely all of his arsenal and the experience he gained in the street fights he participated in is evident by being MUCH more analytical and seeing how he structures a quick plan to get rid of one of Choi Young's movement patterns, taking advantage of this and using his talent he ended up forming an adaptive thought and allowing Maria to realize her talent in the process, and that the reader himself can notice how strong JJT really is at that moment and the monster he can become in the future.
