Mahiro's Weekday Routine (まひろの平日ルーチン, Mahiro No Heijitsu Ruchi) is a special chapter of Onimai: I'm Now Your Sister!. It was originally published in Collected Works Volume 4 which was released on December 31, 2021.

Summary
This special four-panel chapter gives a glimpse into Mahiro's daily routine on the days when she goes to school.

Part 1: Getting Up
At 7:30 AM, Mahiro's alarm goes off. She bashed the snooze button so she can sleep in a bit more. Ten minutes later, at 7:40, the alarm goes off again and Mahiro attempts to hit the snooze button again. Eventually, Mihari drags Mahiro out of bed, telling her that she needs to get up early, despite Mahiro's protests.

Part 2: Getting Ready in the Morning
After getting out of bed, Mahiro brushes her teeth. She then has breakfast, consisting of a bowl of cereal, a piece of toast, and a cup of milk, and gives thanks for it. While Mahiro is putting on her school uniform, Mihari brushes out her hair. Afterwards, Mahiro flicks her hair while looking at her reflection with a smile, much to Mihari's delight.

Part 3: Going to School
After Mahiro leaves the house, she yawns. Eventually, she meets up with Kaede and Momiji, the latter of whom says "Good morning". Kaede tells Mahiro that she looks so cute today, which causes Mahiro to giggle and blush.

Part 4: School
At school, Mahiro reads a book during a classroom lecture. During Physical Education, she pals around with Asahi. During lunch, she sits next to Miyo and savors her food. Later, she falls asleep at her desk while Mari is lecturing, though Mari doesn't wake her up.

Part 5: After School
Once school lets out, Asahi points out a crepe stand. Mahiro, Momiji, and Miyo all get crepes and enjoy them. Eventually, Asahi and Momiji wave goodbye to Mahiro for the day, and Mahiro waves back to them as they all head home.

Part 6: Going Home
When Mahiro arrives home, she yells that she's back and Mihari welcomes her back. Mahiro then enjoys the dinner that Mihari prepared, much to Mihari's delight. Afterwards, Mahiro soaks in a hot bath. After getting out and changing into her pajamas, Mahiro then takes a nap on the couch with a smile on her face.

Part 7: Night
After Mahiro wakes up from her nap, she announces that it is time to have fun. She plays a console game on her TV. She then relaxes a bit by reading some manga. While she is playing a handheld game, Mihari barges in and tells her to go to bed.

Part 8: Going to Bed
Mahiro yawns a bit and decides that she'll go to bed soon. Once under the covers, she takes her handheld game back out and says that it's time for it. She says that she'll play until she gets to a good point. After awhile, Mahiro begins to feel tired, and she eventually passes out, facedown, with her gaming system in front of her pillow. As she drifts off to sleep, a caption reads "Good Night".
