## Summary

Concerned about her sudden weight gain, Mahiro decides to start exercising.

## Plot

Shortly after eating, Mahiro thanks Mihari for the grub and then lies on the couch with a smile on her face saying that she's stuffed. Mihari belittles Mahiro for lying down immediately, pointing out to Mahiro that this is why she's been gaining weight recently. Mahiro sits up in shock, furious that Mihari would say something like that to a growing girl. Stomping off in anger, Mahiro tells Mihari that she doesn't have to be so so rude and says that she's going to take a bath. In the bathroom, Mahiro begins to strip off her shirt, only to get an uneasy feeling at what she sees.

Looking in the mirror, Mahiro cringes a bit at what she sees. Even though she's skinny, Mahiro has a slight layer of flab around her stomach. She notes that it would look perfectly fine to any guy, but that she simply can't ignore it when it's on her own body; she now posesses the female mindset in this area.

Mahiro runs crying to Mihari, begging her to help her, and Mihari agress immediately. Mihari explains that the easy way is to go on a diet for a bit (including cutting out extra sides of rice and cake), but Mahiro says that doesn't want to give up second helpings. Mihari realizes that dieting isn't all that healthy either, and says that it sounds like the answer is exercise, something that Mahiro immediately protests against. Mihari suggests that the two of them go jogging for old times sake, but Mahiro bluntly says that after the last time she's never jogging with Mihari again, much to Mihari's disappointment.

On an early morning weekend, at 7:00 AM, Mahiro wakes up and notes that she may as well go for it. As the two eat breakfast, Mihari bursts into tears over Mahiro actually being up early on her day off. Mahiro tells Mihari that there's no need to cry about it.

After the two get dressed, Mihari tells Mahiro that just walking will help her as well. Mahiro is excited by this and says that it certaintly makes her feel better. As Mahiro leaves, Mihari throws sparks at her telling her to have fun on her walk. Mahiro starts to get a sense of deja vu at this.

As Mahiro walks along the canal, she notes that she's kind of shocked about the fact that she's taking a morning walk on her day off. She then smiles and notes though that it's actually pretty nice and that she's starting to feel better about herself already. Mihari notes that that's the seratonin at work.

Mahiro thinks to herself how the early bird catches the worm, then notices Kaede jogging towards her and notes that this is quite a worm to catch. Kaede is surprised, but happy to see Mahiro and says good morning to her. She notes that Mahiro is on a morning walk and congratulates her for doing so. Mahiro asks Kaede if she's trying to lose weight as well, as she looks so slim already. Kaede sigh a bit and points out that staying in shape takes work as well. She suggests to Mahiro that the two of them jog together which leaves Mahiro horrified. She tries to point out that she doesn't like running, but Kaede pushes Mahiro forward telling her not to be like that. Despite Mahiro's protests, Kaede ultimately forces her into jogging with her.

As the two Jog, Kaede continues to go strong while Mahiro quickly falters due to her nonexistent stamina. Eventually, Mahiro asks Kaede to stop for a minute and Kaede gives her a bottle of water much to her relief. As soon as they're done though, Kaede once again pushes Mahiro forward causing Mahiro to cringe once again. As they continue to run, Kaede gives Mahiro a thumbs-up for effort, despite the fact that Mahiro is at her limit. Mahiro continues to jog until her body starts to overheat and she collapses on a park bench telling Kaede that she can't go on another step.

Kaede apologizes for unintentionally being too tough on Mahiro, but gets Mahiro's attention by reaching into a bag saying that she has a reward for all her hard work. The reward turns out to be a frozen juice pop that Kaede suggests they share. Mahiro is amazed and calls Kaede the best for this. Kaede snaps the pop in half and admits that she did kind of force Mahiro into this. Mahiro slups the treat with a big smile noting that the icy coolness is so nice in her overheated body. She then stops and asks if eating something like this negates the benefits of running as she's trying to lose weight. Kaede says though that it's okay as a little sugar at the right time helps one's body recover from fatigue, saying that it's important part of any workout's cool-downs. Kaede warns her though not to overdo it, and Mahiro understands both points.

Once they are finished, Kaede stretches and tells Mahiro that she's about to head home and asks what Mahiro plans to do. Mahiro decides to rest just a bit longer, and Kaede starts to jog home telling Mahiro not to cool down too much. Mahiro immediately lies back on the bench in relief, noting that she has a pleasant feeling of exhaustion. She notes that she might lose her cred as an "Own-Home Security Guard", but decides that exercising like this every so often doesn't seem so bad.

All of a sudden, Asahi and Nayuta appear in Mahiro's view much to her confusion. The two grab Mahiro with Asahi noting that she's secured. Mahiro demands to know what's going on, and Asahi says in a sinister tone that it's so fortunate that they found her. Mahiro calls for help as Asahi is starting to scare her, but Nayuta clarifies that they were just talking about needing a third person. Mahiro tries to pass saying that she's tuckered out for today. Asahi insists that they play though, with her and Nayuta dragging Mahiro along with them despite Mahiro's protests.

The "play" that Asahi and Nayuta mentioned is revealed to be a game of jump rope. Asahi and Nayuta joyfully swing the rope and sing while Mahiro is forced to jump much to her displeasure.

Later, Mahiro arrives home in a disheveled state, much to Mihari's horror.

At the same time, Kaede shows off her body following her workout. This makes Momiji once again feel insecure about her continued lack of development.
