Ep. 4: Senna empfindet Angst um Junna und Haruhis Zeit zusammen, während sie Akino bei der Dekoration eines Spukhauses hilft.

4

Senna is disquieted at how much time Junna and Haruhi are spending together. Akino asks Senna for assistance because she cannot locate Junna to ask for his. She explains that the haunted house is short on decorations, and since Junna and Senna's parents are archaeologists, they might have materials that they could use. Senna leads Akino and Tomokazu to the mansion-like home she and Junna live in, and reluctantly gives Akino permission to borrow artifacts. When Tomokazu brings up the topic of club members staying at school overnight to finish constructing their club activities, Senna decides to go, despite the Cooking Club being ready. Meanwhile, Haruhi asks Junna to be her date for the Cherry Blossom Summer Festival, but Junna declines because he doesn't remember too much about her. (Source: Wikipedia)
