Find Mei’s Brother Ren
Travel to Karakucho and head for the Breaking Mart to find a Disingenuous Hostess wearing a light brown dress. Speak with her to meet Mei and learn about her missing brother. Head to the Central Line then use the portal to travel to the Northeast Path. Head east until you reach the last room and speak with Sakuro there who will mention a journalist who may have gotten lost in the Lower Area. Return to the portal and use it to travel to Lower Area Center Stairs. You then want to follow the northern path heading through the doorway at the end. Head through another doorway to the east bringing you to a room with a man wearing a light brown shirt and jeans. Speak to this Exhausted Man to meet Ren. This will cause him to leave. Return to Mei to complete the request.
