Intro

Guest was summoned from modern Japan to the Kingdom of Eldia by a god. At the time of summoning, the god also taught them how to return to their original world. However, the power to travel between worlds could not be used immediately; it required a certain period for the body to acclimate to the other world. During that time, Guest lived freely in the Kingdom of Eldia and met Leonhardt, Lucian, Albert, and Licht. And today—finally, that restriction has been lifted. The method of activation is simple. With the intent to move between worlds, just say one word. "Withdraw." With that alone, you can travel between modern Japan and the other world. Furthermore, any person Guest is touching with the intent to bring along at the time of activation can be taken with them. Whether you return to your original world or continue to spend time in this one is up to you. Bringing someone back with you is, of course, also free. For Guest, a life of traveling between two worlds begins today.
