Like a Dragon Gaiden: The Man Who Erased His Name

You just need to complete all the silver battles, no matter what rank you get upon completion, S or C, there is no trophy for bronze battles, but you still have to complete them all, access to some battles will be closed at first.
To unlock the first two special matches of silver and bronze rank, you need to talk to the two brothers "Mr. Hit Me", you will receive messages from them upon returning from the castle to Sotenbori, after receiving two messages from the younger and older brother, return to the castle, talk to one in the casino, next to the exchange and points counter, the second is in the gaming room, opposite the casino, also standing next to the counter.
After the conversation, we go to the coliseum and go through two special fights, the fights are simple, their HP is for one hit, but they move very quickly. and it is no longer so easy to hit them, in the yakuza style, we hold down RB and do a XXY combo, where Kiryu makes a wide kick, even if he dodges, he will be hit one hundred percent. As a result, only one blocked silver fight will remain, this is a sponsor match, it will open when you talk to the director in the lobby of the coliseum (marked on the map with a cup with stars, first go through the rest of the silver and bronze rank fights, otherwise it will not appear), talk to him, he opens access to the last silver rank fight, we get a trophy.
