Leovix's manga / #Yakuza(13)

The female lead is related to Yakuza and wants to teach others. The ML is one of her students. All of her students are very reluctant to being taught as they’re all delinquents. She eventually gains their trust and tries to protect all of them. There’s a good amount of action due to the fact that she’s invoked with yakuza but she doesn’t get rescued by the ML much. She actually has to save him quite a few times and is very powerful. It’s full of comedy but there are serious bits.
