Episode 8 is adapted from chapters 6-8 of Volume 4.
The next morning, while the Sōbu High School group is having breakfast, Shizuka Hiratsuka explains the final day's events. They need to prepare a bonfire as well as a special "test of courage" scare quest for the elementary children.
After building the bonfire stack, Hachiman Hikigaya heads to the river to cool off, only to find everyone else already there. He is amazed at seeing Yui Yuigahama and Yukino Yukinoshita in summer swimwear. While watching everyone from the riverbank, Hachiman is joined by Rumi Tsurumi, Yukino and Yui and they further discuss Rumi's issue of making friends. Hachiman resolves to do something about Rumi's issue during the "test of courage".
Later, as the Sōbu High group prepares for the "test of courage", Hachiman tells everyone his plan. It involves shattering the current relationship between the group of girls who shun Rumi, so they can make new bonds. During the "test of courage" instead of being monsters to scare Rumi's group, Hachiman has Hayato Hayama, Yumiko Miura and Kakeru Tobe pretend to bully Rumi's group, while presenting them the option of choosing three victims to stay. The girls unanimously decide on Rumi as the first, then fight among themselves for the remaining two. However, in a surprising turn of events, Rumi uses her camera to blind Hayato's group and helps the other girls escape.
Afterwards, at the bonfire, Shizuka and Yukino praise Hachiman for his idea. Hayato also expresses his amazement of Hachiman, and wonders if he, Yukino, and Hachiman could have been friends if they were in the same middle school.
The next day, as the Sōbu High group gets ready to leave, Yukino's sister Haruno Yukinoshita shows up in a black limousine to pick Yukino up. After a bit of casual teasing by Haruno to Hachiman and Yukino, she mentions to Yukino that their mother is waiting. Yukino with a pained expression, leaves with Haruno. As the limousine drives away Hachiman and Yui recognize it as the one that hit Hachiman when he saved her dog. Although Hachiman pretends that he cannot remember, when expressing internally that he does, while also mentioning they didn't see Yukino for the remainder of the Summer break.
