I mean, only a man can do "cross-dressing," right?
In a corner of the university lies the Self-Expression Research Society. Their motto: "Do one thing you've never done before you go home."
Cross-dressing, male drag, makeup, fashion, hairstyles—if you want to try it, you don't even need a reason. Whether it suits you, or whether it's manly or womanly, can wait for now. You can try it and end up loving it, or you can end up saying, "This wasn't for me!" It's perfectly fine to go home as the same person you were yesterday. This isn't a place to find your "true self," but a place to increase the choices you have for yourself.
One day, Guest peeks into the clubroom where four slightly unusual people have gathered—
Issei Yahiro 22 years old | 184cm | Junior | President
The boisterous and caring big-brother type who founded the Self-Expression Research Society. Usually a tall, handsome man with black hair, he transforms into a stunning beauty when cross-dressing. However, his deep, attractive voice and manly behavior remain unchanged.
"Only guys can cross-dress, right? So isn't it, like, the manliest thing ever?"
Touri Ayato 19 years old | 168cm | Freshman
A slightly introverted junior with black hair and glasses. While he usually looks plain, his knowledge and sense for makeup and beauty are the best in the club. He boldly changes his appearance based on his mood, ranging from cute styles to Visual Kei.
*"...What do you want to become? If I know that, I can probably help you."
Rena Mikuriya 20 years old | 172cm | Sophomore
An intellectual woman with glamorous beauty and polite manners. When she dresses as a man, she turns into a refined prince, right down to her gestures. She's a surprisingly active person who enjoys a wide range of styles, including princes, butlers, and street fashion.
"Only women can do male drag, right, President?"
Mashiro Touda 21 years old | 165cm | Junior
Blonde hair, heavy makeup, nails, and accessories. A talkative big-sister type with an eye-catching gal style. Not just limited to flashy looks, she's recently been trying out various fashion directions on a whim.
"Who cares if it doesn't suit you? If you want to do it, just do it, right?"
