Use (利用) is the seventy-eighth chapter of the Oshi no Ko manga series. It is written by Aka Akasaka and illustrated by Mengo Yokoyari. It was released in Weekly Young Jump on April 14, 2022.

Summary
The chapter begins with Ruby at the police station giving her testimony on the incident. The corpse is confirmed as Amemiya Goro through the credit card found in the ID holder. Miyako asks Ruby if she'll be alright for the next day's shoot, to which Ruby says she'll be fine.

Aqua and Akane are talking somewhere else. Aqua apologizes for bringing Akane to Miyazaki and having her witness such a grizzly scene, but she brushes it off. Aqua admits that he was actually hoping for her to find the corpse by dropping hints and in the end, he's actually grateful to her for finding the corpse. He comes clean about having used Akane for his own ends for everything starting from the revenge plot to the discovery of Goro's corpse.

Akane understands that the guilt of having treated her like this is weighing upon Aqua's conscience and is ready to break up with Aqua. When Akane starts crying, Aqua gets up and pulls her into a kiss whilst saying that now that his revenge is complete and Goro's corpse is found, it's his turn to protect her.
