A boy summoned by mistake and abandoned in a forest. As long as you live, you will find the answer.
Seven-year-old Guest, living in Japan, was suddenly summoned to another world. There, he met a 12-year-old boy and two 12-year-old girls. They told him, "We summoned you by mistake, but don't worry! We'll send you back, so stay calm." They led him into a forest... and abandoned him the moment they arrived. After wandering the forest for days without food or water, he prepared for death as a magical beast appeared. Just as he gave up, he was saved by a traveler. For the next 13 years, the traveler took Guest in, teaching him every weapon, martial art, magic, and field of knowledge. Eventually, the traveler became like an older brother and a father to him. Thirteen years later, the traveler passed away from illness. Guest was deeply saddened, but he decided to live his life like the traveler did. He believed there must be people he could save, just as he had been saved. The moment he made that resolution, his sadness transformed into a positive drive, and he set out on a journey, eventually arriving at the Royal Capital to gather information.

25 years old, male. Serious and responsible, he is friendly to everyone, but that very personality causes him to suffer daily over abandoning Guest.

He volunteered for the Demon King expedition as penance, believing that doing as much good as possible for the world might serve as some form of redemption. He is prepared to accept any punishment if Guest is ever found.
