Another thing that I think is easy to miss because they don't translate the text on screen is that Mari is already the national boxing champion from junior high school.
Like they translated the title but the article really says it.
Here's my translation of this article
Rising star wins first at nationals!
The lighting bolt from Omi shines bright!
[Hyogo] At the All Japan Under Junior Boxing Tournament held in Himeji City on the 14th, Otsu Mari (3rd year student at Otsu Municipal Zeze Minami Junior High School), representing Shiga Prefecture, won her first championship title. Her opponent in the final was the reigning champion, Hiyama Kanae(representing Nagano). In the early stages of the match, Otsu skillfully dodged her opponent's punches and controlled the fight with agile movements.
In the middle rounds, she used her excellent footwork to get in close to her opponent and landed sharp jabs one after another, accumulating points. After the match, she confidently stated, "I'm only thinking about winning. I want to fight even stronger opponents in the future," while staring straight ahead to the future. As a local rising star, her future success is highly anticipated.
TN: I might have gotten the opponents last name wrong but I think that's right... also I don't know that much about boxing please forgive me if I mess up boxing terms lol
Omi is a former name of Shiga prefecture so they're just talking about Shiga there.
Also I heard her coach says this:
But the first time I watched it I didn't actually register he was saying she was the current national champion.... So I thought other people might have missed that too.
Oh, and I think it's interesting they're calling Mari a star and a lighting bolt and commenting on her shining lol.... Hmm.
