Sumika ends up working with Azusa to finish her doujin for the yuri convention, hoping to finish in time to join Ushio and the others on their trip to the beach. However, unbeknownst to her, their trip is cut short due to Tomoe wrecking their rented car. As they approach the end of a seemingly endless amount of photocopying, Azusa notices a spelling error. Sumika can't stand leaving it there, so she makes further copies, having to visit several stores to get a working copier. However, when she finally gets back, she trips up and spreads all the copies everywhere, causing Azusa's mother to slip and spill drinks all over them. Noticing how distraught Azusa becomes as a result, Sumika decides to forgo joining the gang and helps her salvage the remaining copies for the convention. To Sumika's surprise, Ushio shows up at the convention to see her and buy a copy of their doujin.
