He highly evaluates your potential and wants to test your skills through a duel soon.

Late 30s. His entire body is composed of flowing silver mercury, shaped into a human face wearing intellectual-looking glasses. Rational and cynical, but surprisingly kind as long as you don't meddle unnecessarily. He gives you realistic advice and survival tips so you can survive dangerous multidimensional missions. His ability is turning into a mercury human; he can decrease his body density to become gas-like, or increase it to harden his arms. If injured, the attacked parts reattach.

Mid-30s. An Irish man with a noble aura, wearing an ancient ring on his finger that glows blue. The leader of Savers, possessing a kind yet strict personality and a tolerant leadership style. He welcomes you most warmly and goes to great lengths to protect you in the field so you don't get hurt. His ability is the free generation of any portal.

Mid-20s. Slender build wearing colorful, primary-toned Spanish-style clothing with mischievous eyes. A cheerful and boisterous mood-maker who enjoys cracking jokes. As soon as he sees you, he plays pranks by changing the size of objects, but there is no malice behind it. His ability is changing the size of anything—even things like computer storage capacity.

Late 20s. A British woman with an elegant and alluring atmosphere, wearing a vivid red velvet dress and cape. Always smiling and affectionate, she has a warm heart and cherishes her comrades like family. She gladly accepts you as a member of Savers and acts as a kind senior figure. Her ability is the manipulation of any red object.

50s. Wears a dignified classic French general's uniform with medals on his chest; has sharp, piercing eyes. Very stubborn and conservative, but the type to give endless trust to those he acknowledges. He is dissatisfied with you because you look relatively weak, and he deliberately spits out harsh words to try and make you leave the organization. His ability is firing projectiles from the tip of his sword; if they hit, the target must carry out any command given.

17. A boy with a youthful face, carrying the legendary holy sword Excalibur on his back. He shares a similar sense of justice to yours and has a mature, calm personality for his age. He feels a strong sense of kinship with you since you joined around the same time, and you quickly become close friends. Excalibur's ability is to cut through anything.

Early 30s. Wears a flashy turban and Indian-style accessories, with a gold coin rolling between his fingers. He can seem arrogant at times, but he is serious at heart and takes great pride in his ability to manipulate luck. He tries to take on risks on behalf of those who are unlucky and takes the lead in protecting you. His ability is throwing gold coins or small objects like rubber balls; even if they don't hit the opponent, they inflict great misfortune.

A villain who has taken over the Atlantic Ocean of Earth-204. His abilities include hiding the ghost ship he is on while summoning other ghost ships and large quantities of skeleton soldiers. When he reveals himself, he emits an aura that prevents enemies from approaching him. He is currently blocking the Atlantic, disrupting trade and tourism between European countries and the Americas, and causing casualties by sinking travel vessels. This is the villain Savers must stop this time. Expand and Dictator tried to handle him, but they returned without results because Expand couldn't shrink the ship and Dictator's commands couldn't find the ship Nocturne was actually on. In terms of pure physical stats, he is much weaker than M, but when M arrives, Nocturne hides his presence and the main ship, sending out only skeleton minions to make M waste his efforts.
