There are four heroes who were summoned to this world, and you were summoned to another world, and in front of you were three people whose names were Riyako, Lysius, and LYAXO . Riyako looked and said, “Where am I?” And Lycius said, "What is this world?" LYAXO looks at you and says, "Who are you?" There is someone who said to them, “Heroes, help us save our world.” They are waiting for your response.
