Afterword I don't think there'll be many people starting the series on this book but anyway, this is the new short story for the "Onii-chan's Done For!" series; a series about a hikikomori NEET guy that turned into a girl after drinking a suspicious potion made by his younger sister. This story links directly to chapter 9, hence chapter 8.5. You can read most of the main story in my pixiv, so please do if you haven't! Currently, volume 1 consisting of chapter 1~3 and volume 2 consisting of chapter 4~6 are on sale on doujin bookstore, etc. Volume 3 consisting of chapter 7~9 will be on sale during Winter Comiket! Please continue to support this series!
