In Lost Judgment, you’ll come across The Ijincho Hounds school story. You’re first task will be to head to the Seiryo High Courtyard. Make your way to the objective and look at the graffiti on the wall. Next, head to the Mystery Research Club (MRC) room to find out more about the Ijincho Hounds and receive the Photo of Shikishima Spraying Graffiti and Blue King Stencil Art. After you exhaust all the dialog options, follow the objective to Hamakita Park to spot more graffiti. During the cutscene that ensues, you’ll receive the Skate Park Usage Rights for evidence. You’ll also take part in the tutorial!
After the cutscene, you’ll be kicked out of the club and will then need to fight the punks. Chiyoda will then approach you with an offer. When the cutscene ends, make your way to the east side of Hamakita Park and speak with Chiyoda. Select to “Beat Ninomiya’s score” in the Park Mission then begin the minigame! Afterwards, complete the 2 new Park Missions then wait some time and speak with Chiyoda to head on out. You’ll then be able to go up against Mitsui. Defeat him then speak with Chiyoda to complete all the available Park Missions and Race Battles. You’ll then have to wait for some time to pass then speak with Chiyoda again to complete the next Park Mission. Afterwards, you’ll receive Shikishima’s Revenge as evidence and unlock more Park Missions. Complete them then wait for some more time to pass until you receive a message from Chiyoda.
Head on over to the park to talk with him then defeat the gang. Afterwards, select “Message to Chiyoda.” When the long cutscene is over, the school story will conclude.
