Some mothers who love their sons and want them to have a somewhat happy future enroll them in the Josoushijo programme. Though some of the schools under this programme are pretty evil, and one of the ways they punish their male students is by having them expose the fact that they really are male by lifting their school uniform in front of the rest of the student body which is both arousing and embarrassing at the same time (Those who ejaculate during this punishment are additionally punished with the surgical removal of their male anatomy). During one of these punishment sessions, the protagonist, a first year student by the name of Saotome Asuka, tries to protect his upper classmates from their sadistic teacher.

Tarou accepts and later regrets it when he finds out what kind of ceremony he has to perform. Basically, the shrine's deity is a penis and Tarou has to insert the penis idol inside of him (Tarou does this anally). This causes the penis to upload the entire Kama Sutra into his brain (Tarou's mother explains it with a reference to a USB memory transfer). After this, Tarou's body is prostituted to people (180,000 yen for 60 minutes). It's no wonder Hime didn't want to perform the ceremony~! Meanwhile, Hime is on a date with some hot guy she likes (she gave him a present which is a box full of condoms to use with her). Unfortunately for Hime, she and Tarou have a spiritual link where Hime can feel everything Tarou feels during his session with his first customer: a boy who says he's male, but has breasts and no penis (which traumatises Tarou because he wants to have sex with his sister)... everything degenerates from there...

Little do they know that they're actually friends on the same virtual reality MMORPG. Tough, they both play characters that use some kind of disguise transformation feature to make their character's perceived sex different from their actual sex in reality. (I might be wrong, but I think the boy, while looking like some scantily-clad bishoujo with animal ears, still has a penis, and the girl, while looking like a hot bishounen, still has breasts and a vagina. The girl plays this way because she wanted to get in a lesbian relationship with someone online through deception.)

10) Transfer Students by Orimoto Mimana
Theme: TS (Gradual Transformation and Bodyswap)
To be honest, this story is a rather confusing oneshot story about pornography. I'll see if I can explain it somewhat, basically it's about a boy called Yurio, and his interest with lesbian porn, which caused him to become a perverted outcast from his classmates before Yurio moved to Tokyo. The reason for this was because the other boys in the class who watch porn insisted on heterosexual sex scenes so they can pretend that they're the man in the porn video. Lesbian porn doesn't let them perform this kind of projection, and, based on their logic of projection, makes Yurio a horrible pervert. However, the boys in Yurio's new school in Tokyo are quite accepting of all kinds of pornography.

Yurio also meets a girl called Nobara who also grew up in some unenlightened area before moving to the liberal and accepting city of Tokyo. Because Yurio and Nobara share similar histories, Nobara decides to show Yurio her most important interest, the same interest that ostracised her from her former classmates in her old school: her uncensored HARD BOY-LOVE DOUJINSHI. Yurio becomes enraged because the only pornographic subject matter that should be drawn are lesbians rather than men. Yurio also is distraught by Nobara's lack of understanding of male anatomy in her bishounen (the penises are positioned incorrectly and they have two holes). It is at this point, that Yurio condemns Nobara by calling her a pervert before realising that he's acting no better than the guys from his former school. So, Yurio quickly tries to salvage the situation by adding that he meant pervert in a good way. It is at this time that the wind blows away the pages of Nobara's BL Doujin, which leads to both Nobara and Yurio falling down a flight of 3333 stair steps. Thus begins Nobara and Yurio's journey of idealistic fantasy and reality.

11) (Amoi Jun)
Theme: TS (Clones)
The 3rd continuation of the story from Change-H Blue (and probably Yellow?).

12) Hikarism by Yunagi Kahoru
TG (Josou)
Himuro, a handicraft student, is desperate to get a girlfriend, so he recruits a fellow club member, Hikaru, to dress up as a girl for a day and help him find someone who's his type.

13) (Hitotose Rin)

3rd part of Rin's series. Though, this entry focuses more on the relationship of two of the minor characters from the previous stories.

A flirty classmate - the distressed shop manager - her bitching senpai from work - a cute kouhai from club - follow the eyes of Tachibana, a high-school girl full of beauty, youth and love.

In the near future, a Japanese scientist engineers a powered exoskeleton called "Infinite Stratos" (IS). Possessing technology and combat capabilities far more advanced than any other weapon system, the IS threatens to destabilize the world. Faced with such an overpowering weapon, the nations of the world enact the "Alaska Treaty", which states that IS will never be used for military combat and that existing IS technology must be equally distributed to all nations, to prevent any one nation for dominating the others. The introduction of the IS does however have a major effect on society. As IS can only be operated by women, the power balance between men and women is broken, with women coming to dominate society over men.

Ten years after the first IS were introduced, the world has entered a new age of peace. The peace is shattered, however, by an unexpected discovery. A 15 year old Japanese boy, named Ichika Orimura, is discovered to be capable of operating an IS. Realizing the potential, Ichika is forced by the Japanese government to attend the prestigious Infinite Stratos Academy, an international academy where IS pilots from all over the world are trained. Thus his busy school life surrounded by girls begins.
