Below you will find a walkthrough for Chapter 7 of Judgment called Limelight.
Go back to the Yagami Detective Agency and go to sleep. Then meet Hoshino and talk about the current situation. Outside you will meet a large group of Matsugane Family, whom you must defeat. Deal with the enemies and travel to L'amant. Talk to the woman at the bar and then review documents with Kaito.
Now go to the Hashiki Murder Scene, and then to Queen Rouge. In the later dialog, select Ask Tsukumo, and Open. Then go to the restaurant, beat the Yakuza and take a treat to bribe your workmate. Meet Saori and start the process of beautifying a woman. Start with a disguise and buy it in a shop marked on the map. You can choose what you want - the woman will be parading in costume in the upcoming game fragments, so choose according to your taste.
Now, go to Cherry and choose a hairstyle and makeup for Saori. As before, choice has marginal impact to the game's story and is a matter of your preference. An interesting gameplay fragment awaits you now - you play the role of Saori and from the first person view you have to follow Yagami. Woman makes a stunning impression!
In the following dialogs, select - The name's Saori! I love your Tie, Hashiki-san, Get close to him. You return to the role of Yagami. Wait for a call from Saori and run to the Park. You'll meet Kaito and begin the mandatory side case - Captain Cop. Go to Kaito Ruckus and look for clues about attackers - you need to trace, in particular, the napkins that are hidden under the drawers.
Go back to Kaito and give him the Kaito Lunch Set, which you can buy at Poppo's store. Then run to the indicated place, go upstairs and talk about family debts. After the cutscenes, you're going to have to get the boy back by fighting a group of gangsters.
Afterwards, run to Theater Square, where you will meet the strong Sakakiba boss. The enemy is very tough and strong, so dodge a lot, use the extracts and try to defeat him fast. Run to the Yagami Detective Agency and wait for Saori to call you. Run to Genda and Yagami's hideout again after watching the cut-scenes. Then take a taxi and go to the Prosecutor Office. After watching all cut-scenes you will end this chapter.
