Minamo is a pure and romantic girl who can be quite clumsy at times, and she's in love with the handsome Satoru, a boy in her class. While working at her part-time job, Minamo spies Ryo and his girlfriend Mio as they eat together, their love for each other clearly visible in their eyes. She wishes she could sit like that with Satoru, but she knows she's too shy to ever come out and confess her feelings to him.

Soon after, Minamo is killed in an accident. Filled with remorse at not seizing her chance for love while she was alive, she visits Ryo and asks for his help. If he'll lend her his own life force, she'll be able to tell her feelings to Satoru. Ryo doesn't know until it's too late that lending Minamo his life energy will turn him into a lifeless spirit!

And so the wheels of fate turn, winding the destinies of everyone together: dead Minamo and her reluctant helper Ryo; the pure Mio and her carefree twin sister Mao; the competitive Kokoro, who won't give up Satoru without a fight; the lonely spirit Izumi; and the perplexing Soul Collector. What twists and turns await this cast of characters before the final act is played?

June was rainy. My father came home earlier than usual and said that he's getting remarried.
Then, the following Sunday. Another rainy afternoon. Two women came to our house. One was a gentle-looking woman, the other... a girl with sorrowful eyes. Father announced them as my new mom and sister.
From that day on, life became a haze of confusion. To put it bluntly, I was lost. The girl who shyly glanced up at me and called me "big brother". I’d never properly talked to a girl before, so I had no clue how to handle this innocent, smiling sister.
Eventually, I realized I was thinking about her — Hitomi — constantly. Her pale skin and lips like sakura stuck to the back of my eyelids, flashing behind them every time I closed my eyes. So, that’s why I... assaulted Hitomi, my sister. It happened on a humid, rainy summer afternoon.

You are Takuya Aihara, the hero/heroine of our story. You've been blessed with a very interesting life: several years ago you were changed a girl through bizarre chemistry accidents, not once but twice. Now as you approach your final year of university with faithful girlfriend Asuka at your side, you almost get nostalgic thinking about those crazy days you spent as a girl.

Until it happens again, that is: that troublesome Kouji, still trying to get your female persona in the sack, secretly gets Asami Satoh to whip up some of the sex-change potion and tricks you into drinking it! It'll be harder than ever for you to change back into your male self this time, but you've got no choice: you have to find a way to change back before your female body becomes permanent. Although Asuka is one of the most understanding women in the world, there's no way she'll stay with you as a girl -- that's just not her thing.

As you start another round of bizarre sexual adventures in your female body, the whole gang is back: your twisted sister Natsumi, who loves to tease you; your smart senpai Asami; even the endlessly experimenting Chisato. With an even richer and more complex game story than last time, you'll have loads of fun exploring college life in your new female body. Where will it all end?

I am just an average student, living an average life. I study, I work my part-time job, and get through the day just like everyone else, trying not to be beaten down by the pressures of modern Japan. Then suddenly, the winds of change blow into my life, when I encounter three girls who reshape me forever. Three girls who are most definitely not living a normal life like everyone else in Japan, but who seem to float above society, strangely unaffected by it. Instinctively I know I should avoid getting involved with them, and yet before I know it, my destiny is bound with theirs. Where will it all lead?

A tale of revenge set in future Shanghai, where crime syndicates and cyber-warriors rule the city.

The schools of martial arts can be largely divided into two styles - Waijia, the external schools that concentrate solely on the development of speed, strength, and powerful forms and techniques - and Neijia, those that use control of breathing and blood flow to master the internal energy - qi - that flows through the body's meridians. Because of these methodological differences, the two styles have vied time and again for supremacy.

Although practitioners of Waijia were far greater in number, in the end not one of them could stand up to a warrior who had truly mastered the secrets of Neijia. For centuries, this was the unchallenged law of the martial arts world. However, the advent of cybernetics changed everything. Freed from the yoke of their physical limitations, Waijia schools discovered an entirely new world of possibility. The Neijia schools that had reigned over the martial world with their secret techniques, suddenly found themselves obsolete.

In this age where technology is changing the face of combat, heirs to the ancient martial traditions have developed anti-cyborg techniques for the sole purpose of defeating cyborgs with one's bare hands - at great cost to the wielder.

Kong Taoluo, one such master and former assassin in the Qingyun Society, returns to Shanghai from a year in recovery after being betrayed by the syndicate and assumed dead. Discovering the horrible truth of what has happened to his sister during his absence; Taoluo swears an oath of vengeance and sets out to murder those responsible.

The harmonica, which was handed over together with the promise to that girl.

And within the shaking cabin of the train, Makoto wakes up, dimly but surely recalling that memory ...
