This episode doesn't have any shocking moments, but it's fine as it lays the groundwork for the next big event, which will be the climax of this story. The "duel" between Akutsu and Ebihara is very interesting and effectively establishes both characters. There's a lot of backstory, and even though the anime can't tell everything (it's based on a light novel), you can still see that many of the characters have a rich backstory. It's refreshing to see the members of the group doing friendly activities outside of school; it really strengthens their bond and helps us feel that Kuro's motivation is contagious. If I had to find one word for this episode, it would be: cozy
