Rewatching more of Takafumi’s childhood memories Sumika is depressed they all show her as the vulgar tomboy. While Takafumi is shopping, Yousuke accidentally freezes Sumika with ice magic. Yousuke politely leaves so Sumika can shower but Takafumi returns and accidentally sees her naked. Sumika hopes Takafumi is enticed, but he is so dense he decides to apologise by having Yousuke erase his memory. Sumika furiously stops him and Takafumi believes she is just being a considerate friend. Sumika reveals today is her 20th birthday so Yousuke shows them his 20th birthday memory, where he was alone at a festival but runs into Elga. Elga was surprised but happy when Yousuke suddenly began walking her to his room. Takafumi and Sumika are disappointed to see Yousuke was actually too drunk to walk and was just using Elga as a crutch to get back to his room, and he locked Elga outside and went to sleep. The morning after, Takafumi and Sumika notice that Elga's eyes are puffy and red from crying all night long, but Elga declares she will join Yousuke in dungeon raiding. A memory from the next days inside the dungeon shows Elga was hit by a poisoned arrow and knocked Yousuke unconscious, using a magic item to prevent him remembering anything. However, it is clear to Takafumi and Sumika that the poison was actually an aphrodisiac, and Elga actually used the magic item to prevent Yousuke remembering her satiating her lust.
