Chapter 1 to 10: from Mon. September 2 2002 to Wed. September 11 2002

A girl was teasing a schoolgirl dressed in a school uniform.
The schoolgirl woke up and became mad just like a boy. She seemed to be a bit strange.

--------------------------------------------------------------------------------

Chapter 11 to 20: from Thu. September 12 2002 to Sat. September 21 2002

There was nobody but an elder brother and a younger sister. Their parents seemed to have left.
While the brother was eating fried rice for breakfast, Satori, the younger sister, asked him "to make her a boy".
And he granted her request.
Though his brother was resistant, Satori transformed him into a girl, clad in a housemaid's outfit!

The former sister had gone to the game center, and the former brother began washing dishes, only because she was wearing a housemaid's outfit. . .

--------------------------------------------------------------------------------

Chapter 21 to 30: from Sun. September 22 2002 to Tue. October 1 2002

The ability suddenly "awoke" in a classroom.

Jojima Ayumi was annoyed by the strange phenomena of his chest suddenly expanding and breasts forming.
The phenomena had happened during the day in a classroom or at midnight. They were so ridiculous that he tried to believe "I hallucinated it." each time.

One day, Satori, his sister, brought a sailor fuku (1) home to use it in a crossdressing cosplay held in a school festival.
When she was showing it to her brother, his physical shape transformed completely into a girl!

Notes:
1: A kind of school uniform worn by Japanese schoolgirls. It consists of a long-sleeved blouse, scarf that resembles the uniform shirt worn by United States Navy sailors during and after World War II and a medium-length pleated skirt. The colors and cut depend largely on the school which issued the uniform.

--------------------------------------------------------------------------------

Chapter 31 to 40: from Wed. October 2 2002 to Fri. October 11 2002

Though it was an amazing event, Satori went out of control and said "If I say "Your clothing, become a sailor fuku!" then does the clothing transform?"

Then, the thing she had just said happened!

The younger sister began to tease the former brother, by extending her hair or putting a brassiere on her.
Ayumi, having become a girl, was anxious about "What should I do from now on. . . ?" and yelled at her sister, who took a very optimistic view, as "You, become a boy!"
Then, the sister became a schoolboy!

Jojima siblings were recognizing that they could transform their sibling into the opposite sex.

--------------------------------------------------------------------------------

Chapter 41 to 50: from Sat. October 12 2002 to Mon. October 21 2002

Their mother came in their room when both the brother and sister had been transgendered and cross-dressed!

But she mistook "the former brother" as her daughter and "the former sister" as her son and went away.
That tells them the fact that the transgendered siblings were very similar to each other's original form.

The sister, noticing that "she also could cross-dress", went out of control and changed her former brother's clothing to an athletic shirt and bloomers!

Anyway, this was the first event where they "transgendered and cross-dressed each other", and they decided "to make it a secret and not to tell anyone else."

--------------------------------------------------------------------------------

Chapter 51 to 60: from Tue. October 22 2002 to Mon. October 31 2002

The next morning they noticed they could transgender and cross-dress each other, Ayumi woke up in his bed and found himself transgendered and clad in a uniform for a schoolgirl!

This was caused by her sister, Satori, who was going to "apologize" to Ayumi, and she wore a matching uniform and feel up her.
Ayumi was seriously teased.

--------------------------------------------------------------------------------

Chapter 61 to 70: from Fri. November 1 2002 to Sun. November 10 2002

Since they found their abilities, Ayumi, the brother, became a dress-up doll for Satori, the sister.
The sister bought a full-length mirror, searched her "picture books on female school uniforms" for her favorite uniforms and dressed her brother up in them.

On a certain day, a bizarre problem had occurred. . .

One afternoon, Ayumi, taking a train car to go home, felt that something strange had happened to him.

Ayumi, in a train car, had been transgendered in a very short time and his clothing had been transformed into a pure white wedding dress!

Chapter 101 to 110: from Wed. December 11 2002 to Fri. December 20 2002
Chapter 111 to 120: from Sat. December 21 2002 to Mon. December 30 2002

Ayumi went into a severe panic, managed to get at a window, trying to dash to somewhere deserted as soon as the train arrived at a station.
Ayumi had already become the center of attention in the train car.

At the time, an unknown beauty appeared and snuggled up to Ayumi, dressed as a bride, from behind.

--------------------------------------------------------------------------------

Chapter 121 to 130: from Tue. December 31 2002 to Thu. January 9 2003

The train arrived at the station before the transformation to a girl clad in a wedding dress ended.
Ayumi, having been turned into a girl dressed as a bride, tried to get out of the station with as little notice as possible.

However, a bride arriving at a train station was nothing if not alluring, and onlookers took many pictures.
Ayumi, clad in a wedding dress, ran through the mobs.

Ayumi got out of the train car, ran up the stairs and tried to escape from one of the gates.

The bride, followed by many people just like in a "Royal Parade", and the unknown girl arrived at the gates, and the girl gave a 10,000 yen bill to Ayumi, who was completely broke, which helped her to escape from the station.

--------------------------------------------------------------------------------

Chapter 131 to 140: from Fri. January 10 2003 to Sun. January 19 2003

Ayumi, dressed as a bride, managed to get out of the station and ran into a taxi at a taxi stand next to the station.
However, its driver said "I do not know how to get to that place, for I am a new cab driver."!

--------------------------------------------------------------------------------

Chapter 141 to 150: from Mon. January 20 2003 to Sun. January 29 2003

Ayumi managed to get home. She got off of the taxi.

--------------------------------------------------------------------------------

Chapter 151 to 160: from Thu. January 30 2003 to Sat. February 8 2003

She made herself wrestle the bulky skirt of her wedding dress into the house, removed and picked up her shoes and ran upstairs.

Ayumi broke into Satori's room and shouted at her.
But, the sister, totally surprised, pounced on her without realizing it!

(Illustration)
Illustrated by Ohyuki

Ayumi was teased by being touched all over her body as a bride and having her skirt crawled under!
She somehow noticed there was a magazine that had wedding dresses on the open pages.
They were then recognizing that the event was caused by Satori thinking of wedding dresses.

However, Satori's "attitude of coaxing" went out of control.
She asked her brother to transform herself into a bridegroom!

--------------------------------------------------------------------------------

Chapter 161 to 170: from Sun. February 9 2003 to Tue. February 18 2003

The "manifestation" of Ayumi's power turned Satori into a male, a gallant bridegroom.
Ayumi, "a bride", was made to pose in a swapgendered "bride and groom" position.
She was also asked to "hold his arms".

Furthermore, she, still clad in the wedding dress, was "held up by the bridegroom's arms as if being carried across a threshold". (1)
He turned around and threw Ayumi onto his bed.

At the moment, Ayumi's body was turned back into the original. Ayumi's bag, which had gone away, seemed to have been transformed into a wedding bouquet and reappeared in a corner of Satori's room.

That night, following the day in which the trouble of "transformation into a bride in a train car" had occurred, the Jojima brother and sister had a phone call.
The call was from Kyouko Nagawsawa, who had lived in the neighborhood when Ayumi was a little child.

Next morning, Ayumi's class had a transfer student.
The student was Kyouko Nagawsawa, who had been a childhood friend of Ayumi.

And, Ayumi found that the beauty, who helped him when he was in trouble with his wedding dress, was Kyouko.

--------------------------------------------------------------------------------

Chapter 171 to 180: from Wed. February 19 2003 to Fri. February 28 2003

Kyouko, who was introduced in homeroom class, sat in a seat next to Ayumi's, which happened to be vacant.
Kyouko did not notice at all, that the beauty, clad in a wedding dress and who had problems in a train car, was Ayumi's alternate form. It was quite natural.

And Kyouko spoke, to girls in her class, about the event without noticing that "the real victim" was next to her.
Then Satori, who often came to Ayumi's classroom, interrupted the conversation, which grew more lively.

Making an appointment with their friends to go to a Karaoke Box (1), saying to them, "Let us enjoy ourselves there," and anticipating their arrival after school, early came Ayumi and Satori.
Ayumi, who usually hated transgendering and crossdressing, requested that Satori transform him.
Today, Ayumi was transformed into a "PINK HOUSE" (2) style.

Notes:
1: A common type of karaoke establishment commonly found in Japan. It consists of multiple rooms containing karaoke equipment, usually rented out for time periods.
2: One of the brand name held by Gedix Co., Ltd.

--------------------------------------------------------------------------------

Chapter 181 to 190: from Sat. March 1 2003 to Mon. March 10 2003

Ayumi, who was not very good at anything except "karaoke", had the advantage of being a female.
This was to say, "To sing a song written for a female vocal part with a "female voice"."

After some events, Ayumi, clad in a "PINK HOUSE" outfit, was about to be warmed up.

However, schoolgirls, all of whom were Satori's friends, came into the room.
Though Ayumi was totally upset, her sister began to fast-talk them into understanding, "She was Satori's cousin."
At the time Ayumi was going into a total panic, furthermore, then came Kyouko!

It was hard to bluff a childhood friend into thinking that he had a cousin, and it was unbelievable to try to fast-talk that the name of his cousin was "Ayumi", exactly the same as his name. But things went exactly right and Ayumi was believed without objection.

Just then, Kyouko said to Ayumi, "Have you ever seen me before?"

At the time, Kyouko was aware that Ayumi, as a girl, was the bride in the train car. However, she had told her "I will not tell anybody about the fact."

--------------------------------------------------------------------------------

Chapter 191 to 200: from Tue. March 11 2003 to Thu. March 20 2003

"Ayumi", being a girl, received the microphone.
For Ayumi was a Karaoke-Tyrant, meaning those who would not turn in karaoke, Satori wanted to make Ayumi's turn the last one, but the surroundings made her sing a song.

At that time, Ayumi was asked whether she was familiar with male Ayumi, which was assuredly replied to in the affirmative way, and the question made "the female environment" in the Karaoke Box into mad with excitement.
They seemed to misunderstand Ayumi's reply as "They are intimate with each other."

Ayumi did her best to get them to understand her meaning correctly, but it seemed too late.
And, Ayumi began singing. . .

(Illustration)

As expected, only Ayumi kept singing away and the others could not sing at all.

During the next day, after school.
The sister called Ayumi to the back path of the gymnasium in the school.
And the sister, just came there, and transgendered and crossdressed him again, without any warning.
Into the female school uniform, this time.

Though, she did not have long hair but wore short hair, the same hairstyle of Satori's.
Ayumi, had been transformed into a girl beauty wearing short hair and school uniform, looking exactly like her sister.

To Ayumi's dismay, Satori said she was going to be "proposed" to and asked her brother, as a scapegoat, to "decline the proposal"!
The brother. . . looking like the sister. . . was left alone.

--------------------------------------------------------------------------------

Chapter 201 to 210: from Fri. March 21 2003 to Sun. March 30 2003

Ayumi, acting as a substitute for her sister, was forced to "reject" a schoolboy attempting to approach her sister.
She was transgendered and clad in a schoolgirl's uniform.
She also had short hair, and so looked just like her sister.

She rubbed her legs together under her skirt and stared at her bare legs past the skirt's hem, and in the meantime the "co-star" came.

Ayumi was made to deal with an unfamiliar schoolboy, as "a girl faced with a boy", without much preparation.
Ironically, her silence, which came from her concentration on the problems, was understood as being "while she is usually talkative, she is very quiet today".

Ayumi was upset and tried to run away.
At that moment, she stumbled and started falling, and she ended up being held by the schoolboy.
She managed to push her way through to withdraw.

Though she had "achieved the goal", she had left as a schoolgirl from her high school, as the siblings had no plan about the reverse-transformation.

Though she did not expect she could do it without any risk, such as "doppel-Satori", Ayumi began to seek out Satori, for these problems could not be solved without her.

--------------------------------------------------------------------------------

Chapter 211 to 220: from Mon. March 31 2003 to Wed. April 9 2003

Knowing the risks, Ayumi sneaked into the school building wearing a schoolgirl's outfit.
She thought that she could deceive others, as her appearance was identical to her sister's.

Then, she found Satori talking with her female friends.
Ayumi hid in the shadows and waited until Satori was left alone.

To avoid "doppelgänger problems", Ayumi got ready to concentrate, to transform her into a boy clad in a schoolboy's uniform, on her sister with to trigger once she was alone, away from her friends.
The next moment after triggering it, she sneaked up on him, but. . .
"K, Kawaii!"
Saying that, Satori hugged Ayumi as hard as he could.

Just then, they were discovered by a handsome teacher, who was in charge of Satori's class.
Without deliberately intending to but with some hesitation, Ayumi, "who wore Satori's appearance", introduced Satori to him, as "This is my elder brother. . .".

The teacher was attracted to her, for 'Satori', always very talkative, was now quiet.

--------------------------------------------------------------------------------

Chapter 221 to 230: from Thu. April 10 2003 to Sat. April 19 2003

The Jojima siblings, being swapped, succeeded in turning back the teacher without difficulty.
Ayumi claimed she should be transgendered back soon, but her reply was "Then, why I am being a boy now?"

And surprisingly, Satori spoke out, as "It is a rare opportunity, so let us keep being swapped today.".
While Ayumi (apparently Satori) objected, with tears in her eyes, there came Keiko and Akemi, Satori's close friends who were often along with her, and Ayumi falled to be in the grip of them.
They took Ayumi to the second classroom of the first grade.

Unlike his sister, who often transgender and dress his brother into a woman for fun, Ayumi does not often transgender and dress Satori into a man.
Because of that, there became a great difference in "the degree of profiency" of their abilities.

In the classroom, there presented an unfinished pack of juice.
