I’m looking for something similar to W change!! (and its series Change 2!!). I want the daughter to be strong and capable of fighting on her own. It can be romance but I want the story to focus more on the yakuza part (like maybe the father preparing her to be the next boss or something).

Any other genres is fine but I’m not into hentai, ecchi and such.
I prefer the art to be decent but if the story is good then I’m good with anything.

Thank you in advance.

I don't know if it fits the bill you're looking for but, both of the lead characters are from yakuza. The female lead is not that strong (from the current translated chapters and I don't know in the future coz I don't read raws) but she is capable of defending herself from other people

she was bullied at her school when she transferred because the male lead was paying attention to her which causes several females to react negatively and started to bully her (last for 1 to 3 chapters not sure)

Gokusen is pretty much what you’re looking for. Physically strong and capable female lead. Pretty yakuza like with some comedy. A lot of yakuza focus than romance. Art will put you off at first, especially if you read mainly shoujo. Highly recommended though. One of my fave series~

I'm in idol hell T.T

Oh man I love Gokusen.. that mainly what I came to say LOL

Honestly this isn't really yakuza daughter but Tokyo Crazy Paradise has many of the same vibes someone that likes this genre would like
