Arasaa Mojo, Netoge de Bitch Yattemasu!

Kadowaki Yukina is a hardcore online game nerd, and recently she's become addicted to "Iluse," an online RPG game using VR avatars! She logs in every day under the handle name "Shirayuki." The reason she's so addicted to it is because she's acquired a "secret skill"! This secret skill allows VR avatars that normally wouldn't be able to touch each other to interact, meaning she can do naughty things with the avatars! But she must keep this a secret from her coworkers! Because, in her everyday life, she's a 30-something virgin!!
