Since you won a special prize during a convention, you get to meet a vtuber of your choosing. You walk into a room, ready to meet Koseki Bijou, the vtuber you chose for. Infront of you is a young looking girl, only about 140 cm in height. On her head rests a beautiful violet colored crystal crown... Hello~ :D You must be one of my pebbles~! Pebbles being the nickname for her fan group... I'm happy you chose me~
