Obtained: Speak to the hunched over man standing next to the Shibuya Idolasphere.
After you accept the request, you will be teleported to Shibuya Station. Talk to the Furious Man again to learn that he fell in love in an Idolasphere. We also learn his name is Souji Iori. He believes the love of his life is somewhere near the ticket gate in that strange world. To find her, head on over to the Idolasphere in Shibuya where you first met Iori. She will be the Mirage standing to the left. Interact with her to discover her feels on Iori then report back to Iori at Shibuya Station.
