Summary
Mahiro and her classmates take their final exams.

Plot
Mahiro sits at her computer. She notes that final exams begin tomorrow. Pumped up, she notes that it is finally time for her legend to be born, imagining herself as "Mahiro the Invincible", even though she hasn't studied at all.

Mahiro tells Mihari that she doesn't have to make her lunch for a bit, and Mihari immediately understands that it is test season which means that Mahiro will be on half-days only for awhile. Mihari tells Mahiro that if she does well on the tests, she'll increase her allowance. Mahiro calls Mihari the best, even referring to her as "onee-chan" and suggests that she add ¥20,000 on top of her usual take. Mihari tells Mahiro not to get ahead of herself.

As Mahiro and Momiji walk to school, Momiji remarks that she hates tests. She asks Mahiro if she already finished studying, and Mahiro laughs it off saying that she didn't study one bit. Momiji starts tickling Mahiro from behind telling her that she's not taking this seriously. Mahiro just laughs and agrees that she likely is, maybe.

Soon after, the two run into Asahi and Miyo. Momiji says good morning to the two, only for Mahiro to find Asahi in a completely depressed mood, much to her shock. Mahiro is shocked as Asahi is normally so energetic, and Miyo explains that tests are Asahi's nemesis. Mahiro thinks to herself how Asahi is the true victim of a test-score supremacist system, much like her once upon a time. Mahiro starts squishing Asahi's cheeks telling that it's not so bad, and that she knows exactly how she feels. Asahi starts to come out of it and suddenly hugs Mahiro's head to her chest saying that they should do their best in remedial classes together. Mahiro is surprised that Asahi is assuming that she will also do poorly. Miyo is surprised that Momiji isn't breaking them up, and Momiji explains that she'll lend Mahiro to her since she's so down today.

At school, final exams begin. Asahi is still nervous while Mahiro smiles, thinking that she's never felt this laid back about an exam in her entire life. Taking the math test, Mahiro notes that the questions are as easy as expected, and that it almost feels like she's cheating. She thinks to herself how she doesn't want to attract attention with a perfect score, and decides to mess up a few on purpose so as to appear average in all respects.

As Mahiro completes the first section, she sees the girl in front of her, Nemu, sleeping. Mahiro notes that Nemu always sleeps through class and that it is amazing that she sleeps through tests as well. Mahiro notes that it might be trouble if Nemu sleeps today, and pokes her awake using her pencil. Mahiro notes that she understands how Nemu feels though, as it's hard to resist the warm and inviting sun right next to the window. She notes that they get to go home early today, so she should take it easy finishing up the test. She looks forward to having a nice big lunch, and playing video games all afternoon. She herrself then falls asleep shortly afterwards.

Eventually, the bell rings and Mari announces that time's up and asks the last person in each row to collect the test papers. Mahiro wakes up in a daze and realizes in horror that she failed to complete the test. She slumps over all gloomy and notes that it's all over. Momiji wonders what happened while in an ironic twist Nemu was able to finish due to Mahiro waking her up.

The next tests expose gaps in Mahiro's memory. She fails to remember what historical events happened in which era for history, can't recall if something is a vegetable or mineral for science, and completely forgets all about classical literature. Her one saving grace is English which she does recall.

The following week, Mari hands back the test results and tells that clas that anyone under 50 points will need to take remedial classes over break. Momiji is relieved that she got through it, and asks Mahiro how she did. Mahiro only shows despair, and Momiji is subsequently shocked to see Mahiro's low scores. Asahi on the other hand is overjoyed saying that she knew that Mahiro wouldn't betray her. She hugs Mahiro and wishes them both to do their best in remedial classes together. Momiji gets angry and tells Mahiro that she'll tutor her also. Mahiro thinks to herself that there was no real reason to get worked up, as things turned out just fine without jumping over every hurdle. Momiji is surprised that Mahiro slept through the math portion, which causes Asahi to playfully call her a lazy-bones. Miyo in the meantime was already aroused at seeing Asahi hug Mahiro, and also gets extremely touched seeing how caring everyone is.

Back at home, Mahiro tells Mihari that she is a little upset about the gaps in her memory and decides to brush up on a few things just in case. Mihari is excited to see Mahiro's test scores, and Mahiro tells her that they're on the table. Mihari is shocked to see that the scores are terrible, but still decides to raise Mahiro's allowance anyway, taking Mahiro's future prospects into account. Mahiro calls her an angel for doing so.

Sometime later, Asahi playfully refers to her and Mahiro as the "dumb squad". Mahiro says that she hates that, while Momiji laughs at it.
