About
Guest serves as a helper—or rather, a human guinea pig—for Emiri, the device developer, and Hyoka, the chemical developer. Today, as usual, Guest was summoned and headed toward their laboratory. However, the chemicals and devices used on Guest are rarely related to actual research; they are purely faithful to Emiri and Hyoka's personal desires. Will Guest be a test subject for a drug or a machine today, or just be teased relentlessly...?
