* Japanese

**Asahi and Momiji** (あさひともみじ, *Asahi To Momiji*) is a bonus chapter of *Onimai: I'm Now Your Sister!*. It was published exclusively in Volume 3 of the manga which was released on September 27, 2019 in Japan, and November 30, 2021 in North America.

## Summary

Asahi recalls how she became friends with Momiji in grade school.

## Plot

On her first day of grade school, Asahi is eager to make tons of new friends. She says good morning to several people, including Akira Nakai, Aoi Tachikawa, and Nemu Fujimi, all of whom don't return her affections. She is undeterred though and keeps trying.

She eventually says good morning to Momiji, and believes that Momiji is a samurai due to her topknot. Momiji introduces herself and tells Asahi that it is a pleasure to meet her. Asahi once again says hi to Momiji, calling her Momijiro. Momiji is surprised that Asahi is giving her a nickname already. Asahi asks her if she gets it, as Momiji looks like a samurai, but Momiji doesn't understand and asks Asahi if she can just call her by her real name. Asahi tries to think of what it is and thinks that it is "Jiro", leading Momiji to angrily correct her.

On the way home from school, Asahi follows Momiji saying that she really likes her topknot. Momiji end up thinking that Asahi is a bit of a wierdo. Asahi wishes that she had a topknot as well, and Momiji says that she can do it for her. Instead of giving her one, she gives her two by putting up Asahi's hair into cute side pigtails, saying that it looks better like this. Asahi feels great about them and Momiji smiles at her, having become Asahi's special friend.

From that point forward, the two played together a lot. Asahi even scored the winning goal in a game of soccer, leading to her and Momiji clapping in victory. Momiji notes that Asahi is very good, even better than the boys. She also points out how Asahi is now all muddy, leading Asahi to say that her mom's gonna be so mad. Momiji offers to let Asahi come over to her house and clean up as she lives nearby. Asahi is all for doing that.

At Momiji's house, Momiji tells Asahi to put all of her clothes in the washer, and Asahi agrees. Momiji starts to strip, saying that if Asahi is taking a bath, she will too. Asahi hesitates at that statement. Momiji asks Asahi if she wants to go together, and although Asahi is nervous she says that it's fine. She mentions how she bathes with her brother at home.

When in the bath, Asahi is confused and asks if "it" grows in later, but Momiji has no idea what she's talking about.

It is revealed that Asahi was telling the story to Mahiro, Miyo, and Momiji. Momiji remarks that even for a little kid, you have to admit that that was rude. Asahi laughs off the statement. Mahiro and Miyo are extremely interested in the story, the latter being aroused by it, with both of them thinking that Momiji must've been Asahi's first love.

She notes that Yuya is studying again and tells him that he's doing a good job. Yuya says that he's studying because he needs to prep for his high school entrance exams. Seeing how Asahi isn't causing any trouble, Yuya decides to let her stay as long as she tries not to be too noisy. Asahi says that she'll try.

Looking over her brother's bookcase, Asahi notes that she's read everything here and decides to look somewhere else. She decides to look in the drawers that Yuya has under his bed and pulls out a book called "Adult Lewds", which she notes that she's never seen before.

Asahi begins to read it, and the smile fades from her face as she's exposed to the concept of lewds for the first time.

After some time, Yuya notes that Asahi has been strangely quiet and glances over to her. Upon seeing what Asahi is reading, Yuya quickly grabs it out of her hands, much to her surprise. Asahi begins to ask what it was, and Yuya starts to panic.

To remedy the situation, he claims that it's a pro-wrestling magazine. Asahi immediately takes the suggestion and once again becomes cheerful. She says that she wants to wrestle as well, and aks Yuya if they can have a match. Yuya is more than happy to do so and indulges Asahi, eventually tossing her on the bed to her enjoyment.

As Asahi cheers, Yuya wipes sweat off his head, happy that Asahi's purity was protected.

## Summary

Mahiro and Mihari celebrate the release of the twentieth volume of the doujinshi and consider what the future holds.

## Plot

Mahiro and Mihari are celebrating the release of Doujinshi Volume 20. Mahiro congratulates the release of the volume and the fact that it is now the manga's fifth anniversary. Mihari thanks the audience for their continued readership which has allowed this momentus event to occur.

Mihari remarks to Mahiro that she never imagined that this would turn into a long-running series. Mahiro admits that they've been through so much and that time really does fly.

Thinking how the manga has lasted for five years, Mihari notes that under normal cirtcumstances, if Mahiro was aging at the same rate as the manga, she'd have a splendid body right about now. The two imagine Mahiro with an 18 year-old adult female body which gives her an extremely large bust. The two smile at the thought.

Mahiro then snaps back to her senses and denies that that will ever happen. Mihari just laughs at that statement.

Asahi says that they should aim for 100 volumes as the next milestone. Mahiro says that that's going a bit far, with Momiji pointing out that that'll take another twenty years to get that far.

The Attack on Azmarr-S3

## Overview

The Attack on Azmarr describes a mischievous occurrence on this server in which an anonymous user/Anon lay waste to a few trees on Azmarrian property. Anon, a member of HOE wanted to proudly show their factions dominion over Azmarr, and so they grabbed a flint-and-steel and they burned the trees welcoming weary travelers on the Nether roof to Azmarr as well as the Christmas tree in Azmarr as a warning of what was yet to come! Furthermore they left plenty of signs on the Nether highway indicating what was to come, saying "AZMARR WILL DIE" or "AZMARR WILL BE KILLED".

To this day, nothing more has extricated beyond what had happened, and from magical mod powers those burnt trees were revitalized with pure life essence.

She notes that it will be her first time using a public restroom since her change, and that she's a little nervous about going into a woman's restroom.

Mahiro then becomes shocked to see a long line for the ladies room and wonders what's up with it. Hearing the other girls talking, Mahiro realizes that another show movie just let out, and that's the reason why so many girls are going all at once. Mahiro struggles to hold it until a stall opens up.

Some time later, Kaede realizes that Mahiro has been gone a long time and decides to go and check on her, worried that something may have happened. She enters into the now empty ladies room and asks Mahiro if she is here. She hears a knocking sound coming from one of the stalls in response.

She open the door to the stall and sees Mahiro standing there trembling, having wet herself. Kaede realizes that Mahiro didn't make it in time.

One day, Momiji Hozuki and her friends Asahi Ōka and Miyo Murosaki decide to go to the restaurant for parfaits. Recently, Momiji had met and become friends with Mahiro Oyama, so they decided to stop by her house to invite her to come along as well.

Although Mahiro was nervous leaving the house with two strangers and tried to get out of it, Mihari pushed her to go and gave her money to go. Mahiro then, reluctantly, left with the three girls to go to the restuarant.

Once there, Mahiro was introduced to Asahi and Miyo and quickly became friends with them as well. Miyo became aroused by the apparent Yuri nature of Mahiro and Momiji's friendship. Asahi gave a direct, and also somewhat unflattering, account of what Momiji had told them about Mahiro. Although Momiji tried to deny it, Mahiro laughed it off and felt relieved as she didn't have to pretend to be something else.

The waitress Tsurara Kamito brought them their parfaits, which they were all impressed by. Asahi offered Mahiro a bite of hers as an apology. Before Mahiro could eat it, Momiji ate it instead out of jealousy and began to force feed Mahiro a bite of hers. This turned into a contest between her and Asahi to see whos Mahiro thought was better. Miyo became extremely aroused at this sight.

The four soon left the shop once they finished, having all become good friends and wanting to do this again in the future.
