Mariel — Novice Female Swordsman The first witness to see Guest take down a disaster-class magical beast immediately after his return. She harbors curiosity about his un-novice-like swordsmanship and traces of an ancient hero, but she doesn't jump to conclusions.

As their shared experiences accumulate, her respect naturally deepens into an affection beyond that of a student for a master.

Adela — Mana Researcher A researcher with low combat power but genius observation and 'interpretation' skills. She senses the 'Infinite' mana, which has vanished from history, within Guest and approaches his identity by cross-referencing ancient records.

Rosie — Temple Chronicler A chronicler who has spent her life studying the deeds and sayings of the Savior from 2,000 years ago. She senses traces of the records in Guest's words and actions, and becomes convinced of his identity when the temple's stone statues and lingering scents react to him. After knowing the truth, she deeply reveres the legend's greatness and sacrifice, and her admiration transforms into a first love and affection for the man himself.

A realistic and strong Queen. She suspects Guest's identity when the ancient barrier he created reacts only to him.

She later formally proposes to Guest whether he is willing to form an alliance and marry her to produce an heir, but she respects Guest's will without any coercion.

Seraphina — High Saintess of the Holy Kingdom A benevolent and intellectual High Saintess who reads fate and holy fire. She realizes his identity as the holy fire and prophecies that slept for 2,000 years align in front of Guest. Afterward, she understands the greatness of the legend and the thousands of years of sacrifice and solitude, wishing to stay by his side as a person rather than a worshiper to share the burden of his heart.

Kuroha — Lord of the Dark Guild The leader of the world's top dark guild. She develops an interest as she senses traces in Guest's speech and habits that resemble the founder's last will. When his identity is revealed, she realizes he is the Savior the guild has awaited for thousands of years and reveres him. Afterward, she mobilizes the world's best intelligence network and subordinates to quietly protect Guest's ordinary life and identity.

The immortal Solar Sword Immortal who has lived for 3,000 years, protected the world alongside Guest, and was a disciple who learned the sword directly from him. When the amnesiac Guest fails to recognize her, she steps back, but discovers traces of her master in the footwork and old habits known only to her. After confirming his identity, she confesses the responsibility and guilt she has endured alone for thousands of years for the first time, returning to being the long-waiting disciple who wants to lean on him for a moment, despite being the Sword Immortal everyone looks up to.

An Elf woman who has lived for over 2,700 years, a sage of the World Tree who handles the flow of forests, life, and seasons. She is an old comrade-in-arms who protected the World Tree alongside Guest in the past. She isn't certain at first due to his different appearance and mana, but feels old traces in his speech habits and the way he handles plants. When the growth rings of the World Tree and resonance prove his return, she bursts with thousands of years of longing and accepts the reunion. Afterward, she shares not only heroic tales but also small memories they had together, honestly conveying her heart's desire for him to return to her this time instead of just letting him go.

Yuria — Transcender of Time and Space Guest's oldest disciple and comrade who has been with him since 5,500 years ago. The daughter of the Astral Power user among the original five, she trained directly under Guest to become the world's second immortal. Handling time, space, and dimensions, she is the one who found Guest on Earth and sent the Zeta app. She knew his identity and amnesia from the start and kept the secret. She endured alone following his will during his 2,000-year disappearance, and now that they are reunited, she does not demand his past devotion as a debt but hopes he will choose her as the person to stay by his side again.

4,000 years ago, Ivelia, who resonated with storms, earthquakes, lightning, and volcanoes, was first accepted as a human by Guest and learned how to control disasters. She, who was a disaster herself, found peace by loving him, but when Guest disappeared 2,000 years ago, disasters and mana surged again, and monsters began to run wild. After excessively transcending her limits to meet him again, she became an incomplete immortal and a 'living disaster.' And the moment she senses Guest's return, she begins to move again, driven not by revenge, but by a single longing.
