Unknown

Unknown (real name Saeran Choi), is one of the main antagonists of the Mystic Messenger. He is the identical twin brother of Saeyoung Choi and a disciple of the organization Mint Eye. In Another Story, Saeran continues to use the screen name Unknown, but now goes by the alias Ray.

Saeran is very hostile and defensive towards everyone, particularly his twin brother, Saeyoung (707). This is due to having been "brainwashed," drugged, and tricked into believing he was abandoned by Saeyoung when they were younger. He has become very paranoid and refuses to trust anyone for fear of being betrayed again.

In Another Story, Saeran has two different personalities, Ray and Unknown, which is likely a side effect from ingesting Mint Eye's elixir of salvation for several years. The two personalities are aware of each other and are able to communicate with one another. As a hacker, Ray and Unknown have extremely different skill sets with Ray's skills being on par or even being better than Saeyoung's. At the moment which one is Saeran's original personality is unknown.

For the majority of the route, Ray is the dominant personality. He is gentle, sweet, and terrified of being abandoned. He is against violence, and cannot bring himself to hurt another living being. He was obsessed with MC, and only wants to make MC happy and keep her MC at Magenta.

Ray was also terrified of having Unknown's personality awakening and taking over.

On the other hand, Unknown is the complete opposite of Ray and extremely dark in nature. He desires the destruction of the RFA and those that oppose Mint Eye and him. Unknown was mostly suppressed by the effects of the elixir of salvation, but Ray's last dosage had him taking over Saeran's body. Saying Saeran's name also has the effect of awakening Unknown. Unknown seemed to hate Ray, calling the other personality a marshmallow boy, and disliked Ray's crying and whining.

He has white hair with light pink tips and mint-colored eyes. He is seen wearing a red tank top with a black patent leather jacket over it. He has a black choker around his neck, as well as a black spiked bracelet on his right wrist. He has a more modernized version of the Mint Eye symbol tattooed to his right arm. At several points of the story events, he wears a black mask that covers the lower half of his face. In Another Story his hair is better groomed. He's wearing a magenta tux, with a blue rose on his tux. With his tux he's wearing a tan pair of pants.

In the past, he had scruffy vermilion hair and golden eyes like Seven.
