"I've been searching for you this whole time. You can't fool my eyes." The road to school is full of danger! As Bocchi tries to hide her presence and make it to school she runs into a bright foreigner?!

Aru attempts to save face in front of her friend Hanako Yamada after she accidentally brings an elementary school backpack to school with her. Things become more difficult for her the next day when she ends up wearing a full elementary school uniform. Later, Aru is challenged to a tennis match by Nako, finding it difficult due to all the times she's been skipping tennis club.

Bocchi becomes nervous about presenting a haiku in front of her class while Nako ends up having to take supplemental lessons after failing her maths test. Meanwhile, Teruyo, trying to get over her fear of Nako, makes the assumption that Bocchi is a secret gang leader.

Feeling she needs to make one more friend before summer break starts, Bocchi attempts to befriend disciplinary committee member Kako Kurai, only to fail miserably. During summer break, the girls go to the pool, where Bocchi teaches Nako how to swim. When the girls go to karaoke afterwards, Bocchi comes across Kai, who is relieved to see that Bocchi has made some friends and remembers her promise to her. On the way home, Sotoka expresses her desire to become friends with Bocchi to the others.

During cooking class, Bocchi ends up having to work with an unfamiliar group of classmates. With some help from Aru, Bocchi manages to impress her group by making them some whipped cream for their pancakes. Afterwards, Bocchi works up the courage to introduce her friends to Kako before asking her to join her group for making curry during an outdoor class. After a successful curry, Kako acknowledges Bocchi's determination to become stronger and declares herself as her rival.

Strong Bocchi powers up! Today she's Super Strong Bocchi! And Sotoka becomes Super Strong Sotoka too! What's making her stronger than usual? ...Her shoe?? Natto?!

If she doesn't talk to all of her friends every day, they'll forget her! While Bocchi has more friends now, she has more worries too. What should she do to ensure she remains friends with everyone? Make her CD Debut?!

Finally... Finally... Bocchi has a smartphone! Now Bocchi can join the smartphone tap-tap group too. Yet first she takes her friend's advice and greets her phone. So when it responds and she asks it to be her friend...?
