you used the Chinese raws and it seems like you TLed from it but rewrote parts that you didn't get

001
OG: 文句は夜逃げした親父さんに言ってくださいよ
TL: "If you have a complaint, go tell your runaway stepfather, 'The Hero'"
ED: he doesn't call him a stepfather or hero, he just tells her to complain to her old man who ran off at night. the Chinese scan says stepfather though (繼父)

OG: ギャンブルで溜まりに溜まった借金１千万円
TL: "Your stepfather owes me a full ten million"
ED: he specifically says it's a gambling debt. also not stepfather

OG: キッチリ穴埋めしてもらわねぇと
TL: "I have to ask you to obediently give mem the money and pay it back"
ED: he says she needs to make up for the debt somehow

OG: 黙れクソヤクザぁ！！！
TL: "Shut up you BASTARD!"
ED: the Chinese scan also omits the fact that she calls him what he is, yakuza

002
OG: その日のうちにこの体たらくだもんな
TL: "Look at how weak you've become now"
ED: he's talking about her condition within the span of a day. the Chinese scan slightly alters this (過陣子這幅肉体應該就徹底堕落了)

OG: 「頂点の女」の二つ名が泣くぜ？
TL: "What was that, Hero's Daughter?"
ED: he's mocking her for crying despite having the nickname "Lady Apex"

OG: うるひゃいい
TL: "吵死啦啊"
ED: wrong language

003
OG: 女子総合格闘技チャンピオンの華頂優良様が
TL: "I didn't expect the undefeated champion of the Women's Fighting Competition, miss Asami Momoko"
ED: female mixed martial arts champion, Kachou Yura

OG: 借金をチャラにする試合のために一週間絶頂禁止の条件を
TL: "Remember our arrangement. I'll allow you to fight me in the ring for the chance to excuse your debt - "
ED: he just says a week without cumming should make up for the debt they owe. it seems like you didn't understand the Chinese here and just rewrote it (我記得當時為了還清你欠的錢, he remembers when she first accepted the bargain, cont'd in the next bubble)

OG: 大したことねぇって大見得切って飲んだのはアンタだろ？
OG: "If you can last a week of me playing with you, without cumming"
ED: this should be in the previous bubble. he's talking about how she accepted the deal with a grin on her face

etc

I imagine an epilogue.

-Katsuma: I'm disappointed that you gave up without a fight, you looked like a coward, destroying your reputation in the process.
-Asami Momoko: What else could I do? We both know that you would have torn me to shreds in less than 1 minute.
-Katsuma: Obviously in a real fight, I would have torn you to shreds. But you forget that this is a show.
-Asami: I don't understand.
-Katsuma: There is nothing fun about a fight ending in less than 1 minute, so I would have held back, to make it seem like we were even, and in the last round is when I would knock you out.
-Asami: Does that mean that? ..
-Katsuma: Yes, you looked like a coward for nothing.
