Obtained: During Chapter 6, speak with Ayaha in Fortuna Office.
Travel to Shibuya Station then head straight, passing through the headphones. DO NOT CROSS THE STREET. After passing through the headphones, take an immediate left to head down a narrow sidewalk along the street. Speak with Tobita, the hunched over guy wearing a black and white jacket.
It’s no surprise that his Performa was stolen so now head back to Ayaha to report the news.
Tiki sensed a strong presence at Daiba Studio’s Idolasphere, so it’s time to head on over there. When you arrive, go through the door on the right to reach the Back Monitor Room. Proceed through the door under the monitors and head right. Keep going straight down this hallway until you reach the glowing Mirage at the very end. When you approach this Mirage, a fight will trigger with a Regal Paladin (level 58) and 2 Red Shamans (level 58). Defeat them all!
Exit the Idolasphere and head back to Tobita at Shibuya Station to speak with him. When you find out that he’s fine, report the news to Ayaha to complete the request.
Reward: Clap Track
