Partial Friendship is the tenth episode of A Place Further Than the Universe.
Upon arrival at Syowa Station research base, the girls are put to work moving gear and doing cleanup. Yuzuki gets an e-mail saying that she has been chosen for a role in a TV show. She isn’t sure if she wants to do it, but accepts when she hears Dai Himi listening to her pop song, realizing that it will make the others happy to see her in the show.
Yuzuki sulks when she finds out that the others became best friends but didn't invite her. They discuss the nature of friendship. The expedition celebrates Christmas.
Yuzuki breaks down in tears when the others come to celebrate her birthday, which passed by unnoticed during the voyage while they were seasick. Later Yuzuki apologizes, “Sorry, ne(ね)?” Kimari comments on this, noting how the word 'ne' (ね) implies friendship.
- When the girls see some penguins, Kanae reminds them to stay within 5 meters. This refers to a general rule for visitors to Antarctica that they stay 5 meters away from wildlife. If a bird approaches a person, then it's okay to let that happen, but not to pet them or handle them.
- The use of ね (ne), commonly translated as “right?” carries an implication of friendship. The word was used previously in Episode 3, when the girls explained to Yuzuki that they were not friends, having only just met. But using 'ne' amongst each other implied the togetherness of friendship, as if they hoped to become friends. Here in Episode 10, it is used by Yuzuki to ask, "we're good?", between true friends.
- "Keeping busy is the best way to speed the clock’s hands!" - Hinata Miyake. This is another of her made-up sayings
The insert song for this episode is "Mata ne".
