Episode 4

Graduation (卒業, Sotsugyō) is the fourth episode of the Welcome to the Slave Harem in the Labyrinth of the Other World anime series.

Plot
With his extra money, Kaga is able to afford a larger room. Roxanne is noticeably nervous and Kaga realizes he mistakenly got a room with a double bed, compared to two single beds, and is afraid the thought of sharing a bed scared her. He is able to reassure her that as well as sharing his bed he mostly wants her to accompany him into the labyrinth as a fighter. After purchasing all Roxanne's adventuring equipment, including underwear, they return to their room. Roxanne proves adept at repairing and maintaining equipment, but they both grow more nervous as night approaches. Kaga is unable to stop himself from looking at and touching Roxanne's body, but feels incredibly guilty for it. Despite the awkwardness, they manage to wash each other's backs, Roxanne's tail and shampoo each other's hair. Finally, they get into bed together and, while trying to make sure Roxanne enjoys herself as much as he does, they have sex. The next morning, Roxanne kisses him but Kaga suspects she only did so because he asked her to before they fell asleep. Regardless, Kaga decides to begin their first trip into the labyrinth.

Trivia
The episode is the adaptation of chapter 6. However there are a few differences:


 * The scene with Roxanne and Kaga leaving Alan’s merchant shop has been removed from the anime, instead the episode starts with them booking a room at the Pavilion.
 * In the anime Roxanne receiving the sandals and being embraced by Kaga is switched around compared to how it happened in the manga, while their weapons conversation isn’t present in the anime.
 * In the anime the dinner scene isn’t present, while in the manga it was here where Roxanne tells Kaga that it isn’t normal for slaves to eat together with their masters.
