The next page of our guide to Judgment contains a description of Chapter 10 - Chumming the Water.
After the cutscene, use the drone to examine the Matsugane Family Office. You will follow Higashi, assisted by a few of his vanguards. Be careful, as this sequence is a little bit more difficult than others - the more people , the more often they turn back, and you need to use hiding places a lot. You'll finally get Higashi - run after the man and talk to him.
You must now force the Matsugane Family to come out of hiding and face you. Go to the next points on the map until you reach the Tender bar where you can talk to Mari. Watch the man next to you and select He'll go after two more drinks. After that, go to Alvin's club and beat up some gangsters. Repeat the fight several times and then run to the Champion District.
Beat all men sent by Matsugane Family and then chase the fugitive. After cutscenes, go to the Soleil Building, open the lock and enter the building. You have a lot of fights ahead of you, including a few fights with Cane Man, who will use completely different weapons. You have to prepare yourself well for the duel - buy first aid kits, food and create some extracts. You must break through the waves of enemies until you reach the top of the building.
Upstairs, you're going to duel with Captain Hamura. He's a strong opponent. You have to block his punches and try to control him. Don't get caught in his strong combinations of blows and combos! After a successful combat, the chapter will end.
