Itsuki finds Maiko having a hangover at her desk, due to excessive drinking the night before. She tasks him with having Tiki make her medicine, with Tharja noting that this isn't the first time they've had to help Maiko. However, Tiki realizes that they used the last of the medicine the previous time Maiko had a hangover, forcing Itsuki to go to Illusory Daitama to gather the ingrediants.
After securing the ingrediants and making the medicine, Maiko quickly recovers from the hangover. Kiria explains to Itsuki that Maiko often attends drinking parties with other members of the entertainment industry in order to ensure career oportunities for the party. She also uses this time to negotiate with the police to help cover up the Mirage incidents, allowing them to hold their investigations uninterrupted. Itsuki notes that they should be more grateful to Maiko for all the work she does from behind the scenes.
Completing this side story unlocks Maiko's Backup Skill Drinking Connections, which increases the money earned from selling items.
