The panels I followed looked like Busaba wound up and got a good start on her punch and after the hand hit her hand was both blown back, and stung, so looks like a fair amount of agreement with my assertion that punching hands hurts, just not the assertion that something should break because the MC has a history of not regulating her strength because she's an (extremely) amateur boxer. I presume you've read the manga, but if not, I highly recommend it so you can see that particular fact repeated in the story numerous times.
In any case, I'm not interested in debating this with you anymore, you're not presenting compelling arguments here when you reference Ali when we're talking about a character who is on her 2nd fight and is still struggling to throw jabs consistently. It's ridiculous bordering on "Is this guy actually being paid to stan this obscure mid 2000's manga or something"?
No she put her hand up, she did not wind up. That is the point Busaba thinks she can continue punching but Okome is literally just putting out an extended jab before she can react. If she had wound up then she would have had more turn in her body to bring her fist back behind her shoulder, like a hook, she had her elbow even with her shoulder, and when the jab connects, her elbow is STILL even with her shoulder. The fact is that Okome, with no step-in and full extension, hit her hand which caused her arm to rotate back from the shoulder upwards: Okome’s punch hit Busaba's hand BEFORE it had a chance to get moving. YOUR assertion was “i know it's not
realistic realistic but c'mon, hands punching each other is gonna break something.” so now you had to walk that back.
My point is that it IS realistic and she is throwing a jab from a crouched position into a non-moving fist akin to mitt work which would not break anything and once again you literally could not read that FIRST part of the sentence for some reason. You don’t have experience with boxing and are having trouble understanding the mechanics in the panels while reading them for you to come to the wrong and incorrect conclusion twice now.
To the point about her strength: that comes up when she is launching a punch from an upright or supported position (usually with a step in) which literally comes into play in the rest of this chapter. On pg 7 where she says “don’t want to run away anymore” it is literally referencing the mechanics I’m talking about and doing so thematically. She is not strong when she is timid or backing away from confrontation yet is still powerful enough that a bad punch from her in that disadvantageous position turns things around: when she decides to move forward there is practically nothing that can stop her. pg 8 show them recentering, notice how she has regained her upright position. pg 13-14 notice how her punch and extension have distinct power lines because SHE HAS A STANCE AND IS STEPPING IN. pg 15. Upright stance POWERLINES. pg 18. instead of shirking back from the punch SHE HAS STEPPED IN so far that their legs have overlapped: kinda like how thematically in the fight this is the first time their foundations have overlapped and Okome is doing so by utilizing something that she’s learned from her experiences to literally bash the core of her opponent which seemed to be so strong. Like the moves in the fight actually mean something to the story and the art is meant to convey that.
You’re not interested because you tried to say something initially when you really had no idea: that’s fine.
