Gacha Gacha - Secret

Akira Hatsushiba is just your typical, average high school kid . . . until a glitch in a Gacha Gacha video game changes his life forever. Now, every time Akira sneezes, his entire body undergoes a gender-bending switcheroo! That’s right, Akira is always just an achoo away from getting in touch with his feminine side. But it’s not all bad. Akira has had a crush on Yurika Sakuraba ever since he first laid eyes on her. He’s always been too shy, but now that he can change into a girl, Akira finally has a chance to get close to Yurika. Being a girl certainly has its advantages!
