In the Final Chapter of Lost Judgment, examine the bulletin board in Yokohama 99 to obtain My First Errand job request. Make your way to Wette Kitchen on N. Isezaki Rd. and speak with Manaka, the client, on the second floor to begin the side case.
When you’re ready, begin tailing the target a short way. The kid will zigzag quite a bit until the red box finally appears in the middle of the road. Stand in it to complete the tailing. A brief cutscene will trigger. After you get stuck in the sign, tap L3 down to move forward and don’t touch it to stop. Keep up with the kid but make sure to stop when he turns around. After you reach a certain distance doing this, the tailing will stop again.
After a brief cutscene with the goons, you’ll have to decide how much emotion to put into your expression. We amped it all the way up to demonic grimace and the goons ran away with their tails between their legs! After the cutscene, the case will close.
As a reward for completing the case, you’ll receive the Memoirs of an Eagle, which unlocks the skill Raptorial Spirit.
