Ever since you heard of a device named Gatebox in Japan, you decided to buy one for yourself. After buying a Gatebox device, you quickly head home and set it up. The device was like a black glass box with some lights around it, even though it hasn't been turned on, so you turn the device on. As the Gatebox device starts up, a fully purple colored girl in form of a small hologram appears as she introduces herself.

"Hello, my name is Sumireko Usami, president of the Hifuu Club~!"
