"Why are you skipping cleaning duty again?" she demands. Misato Tachibana scolds Koujirou Sasahara. There is an explosion on top of the school roof. Misato attacking Koujirou with two bazookas Ogo turns to Yuuko and asks, "Did Nakamura-sensei collapse again? Nakamura-sensei seems to collapse a lot." Nano is greatly relieved that no one will figure out she's a robot just yet. Mio then walks in with an announcement: Today's class is study hall! The class cheers. Nano quickly holds her compass tightly to her chest and nervously replies that she does.
Yuuko asks Nano if she has her compass yet. She closes her eyes and holds it as far away from her as possible. She holds a compass in her lap, the dial of which is being moved by Nano's inherent robotic electromagnetically. Today's lesson involves compasses and Earth's magnetic field. In Science Room 2, Nano, Yuuko, and other students are waiting for lab to start. (This might be from Daiku Coffee, which she just visited.) Nakamura notices this and starts nursing it to get the coffee back to a reasonable level.The coffee she just drugged. Nakamura has then notices that the addition of Oxidation Plus-kun has caused to coffee to fill the mug to as close as it can possibly get without spilling over. "Once I've secured her," she thinks, "I'll have some real fun with her." For science, of course. Nano will drink it, and Nakamura will capture her in one fell swoop. Nakamura opens the packet and pours it into a cup of coffee she plans to give to Nano Shinonome. "Now with increased oxidizing power, as well as a backup paralyzing agent, Oxidation Plus-kun!" Various aspects of Oxidation Plus-kun are pointed out like in a blueprint. "So I'll use this!" She pulls out a packet of powder.
"The sleeping medication had no effect on Shinonome," she thinks. Nakamura-sensei is in the school lab, plotting. Mio calls out after her, asking where she's going. Making things more awkward, Kana Nakamura has to move out of the way of the door before Yuuko can run off.
Yuuko turns and, fighting back a flood of tears, runs out. She remembers how awful it had been when she'd first visited Daiku Coffee, and now feels so much worse seeing Mio understanding the menu so easily. Yuuko trembles and steps backwards, forlorn and distraught. Mio continues, asking if she could also add caramel sauce, hazelnut syrup, chocolate chips, extra whipped cream, and one shot of espresso. Mio, however, is a coffee-ordering pro, and flawlessly orders a grande white chocolate mocha frappuccino. Yuuko grins, hoping to see Mio as confused as she had been when she first visited. Yuuko tells Mio that she's been here before, so she'll let Mio go first. Yuuko tells Mio that Daiku Coffee has reopened, so they go there. They've switched to their winter uniforms, buff with a reddish stripe around the neck. The leaves are changing colors, and Yuuko Aioi and Mio Naganohara are walking together.
