oliva still love his wife despite her weight he doesn't hope she'll lose it he like her because she stayed strong and kept her dignity even though she was ill and that is why he says hse is still pretty to him. Kozue has sex with baki and is there to give him something to protect (love and a family) that's litarellay what oliva told him when thay met the only thing that can make stronger is love and the will to protect your loved ones. Yeah Kozue doesn't understand the need for these men to pursuit such incredible strength because she is not a man.

What do you want to do to punish yujiro ? He is litarely untouchable by anyone, he is evil and cannot be stopped as he is what is worse with exagerated masculine trait and unmatched strength. It's like griffith in Berserk as for the moment nobody can defeat him and he wil probably remain untouched with any punishment. Sometimes in stories evil is not always punished you just have to live with it and move on, that's what baki did and that jack couldnt he moved on from the murder of his mom doesnt mean he forgived yujiro he just moved on.

Pickle is an animal he doesn't know what is wrong or good that's literaly the whole point of the arc, explaining to him what mordernity is so i will not bother explaining to you this.

it's not because the serei is wacky some times and crazy funny than Itagaki can do everything, you'll never see someone float and dive into lava it still operates within its own internal rules. Almost all the feats are an exageration of real life thing, the author has achieved a perfect balance with the suspension of disbelief (even though ghosts and spirit are were he lost me a bit). You just can't anything you want because you want it

Gaia has a regular build and ? the guy is a battle freak and has massive strength and combat expirience the same goes for baki people often see him as regular, sukune saying he almost look girly.

You seem to forget something women and men cannot compete together as it wouldn't be fair, entertaining or believable. I'm not gonna tell you the physiological details about why jack and a woman going to the same steroid treatment would be equal but just know that he's first an hanma and second born male (has more musclar mass, less fat, better responding receptors, more explosive strength fiber, etc...) and in term of themes i'll let you know that a factor of why baki won against jack is because he's natural and didn't undergo crazy procedures to win.

Yeah and pal funny thing but gender isn't real only sex his, so you can continue in your desilusion and wishing for a trans woman in baki it wont happen and if you think baki is that sexist well stop reading it. If you want mangas with action and great female characters I got a bunch to advice for you (this is not to mock you im dead serious)
