Mystery is an idol who came from Pritaly. He's a Royal Type idol, and the first idol with a Secret Type to arrive in Parajuku. His brand is Mr. Mystery, a brand he created himself.
He is an android who was created to replace the Clock Princess Hiyori Kamiri as the holder of one of the Five Seals needed to keep the balance in the timelines.
Him, Haruka and Flower replaced the members Hibiki Shikyoin, Halulu Bokerdole and Falulu Vocaldoll of COLOR, in order to save them from Tenshi Bokerdole's plan. They're very close, even now, and are planning to become an unit.
He refers to himself as the Demon of Countless Masks, and a thief.
Mystery is a tall boy with fair skin, spiky blue hair tied in a pigtail and blue eyes with stars inside, a symbol of his rare shapeshifting powers.
Mystery also has two purple horns, a pair of wings and a tail of the same color. It's revealed they're real.
After forming Dream♦SPECTRUM, his Casual and Cyalume Coord is the Mystery Brilliant Prince Cyalume Coord, a MR Coord from the arcade.
As a student of PriPara Idol Academy, he doesn't wear his uniform, often getting punished by Shine, who seems to dislike him.
Mystery is quite flirty, and likes teasing others. He considers himself everyone's friend, acting nice to anyone he meets. Despite masking it with his perverted personality, Mystery is very sweet, well-mannered, a little shy and always puts others before himself. He also gets angry very easily, and can be quite stubborn when upset, acting anything but gentle.
Having suffered a lot in his past, Mystery does his best to help others out when in trouble.
However, Mystery is also quite competitive, always looking for strong rivals who can put up exciting shows, and who can catch up to him.
On stage, he acts like an average Cool idol, and he's the first Divine Idol in Pritaly. He is the idol who brought the new Cyalume Change, Cyalume Type, to Parajuku, along with the Secret Types.
Mystery is also a very good actor, being able to put up acts for a long time, as seen during the years he took Hibiki's place. He's also able to mask his feelings very well, but he learnt to open up to others and occasionally cry when he can't take it anymore.
When speaking, Mystery often dramatically poses.
- Royal Thief Coord: His first casual coord, and the coord he will wear during his debut live in Japan.
- Mr. Mystery Cyalume Coord: His first Cyalume Coord.
- Mystery BP Cyalume Coord: Team Cyalume Coord.
- Haruka Shirogane: They're a couple. Haruka instantly recognised Mystery, but never told him. Even before he acted as Hibiki, both really loved each other, and swore to stay together forever. Mystery is slightly overprotective with her, but Haruka claims he's actually pretty sweet and too shy to show it, masking it with lewd jokes.
- Flower: Mystery's adoptive sister. They're usually seen together, and get along very well. Both deeply trust each other, and Mystery calls her a "partner in crime". They always agree on everything, and Hilulu believes they are a perfect duo. Flower usually scolds him when he's being lewd.
- Hibiki Shikyoin: It's revealed Mystery took Hibiki's place ever since COLOR debuted, in order to save her from Tenshi Bokerdole's plan, which could have killed a normal human. The two are finally getting along and consider each other ultimate rivals.
- Shine Shiroumi: Shine dislikes Mystery, and tends to give him Warning Tickets for stupid reasons, such as "being a perverted fool".

- Lillie Nijiiro: One of Mystery's best friends in PriPara. Mystery likes to see her as his kohai, and as the future of PriPara. He loves her tea.
- Hanako Inoue: It's not clear whether Hanako wants him dead or is totally a fangirl. It is probably both. EDIT: Yes, it's both.
- Aki "Hilulu" Shikyoin: Hilulu doesn't really like Mystery's attitude, and would like to know what he's actually planning.
- Falulu Vocaldoll: Both really respect each other, as idols and rivals. Mystery admits Falulu is a wonderful idol, and deeply admires her.
- Fuwari Midorikaze: She's his unit's manager, and he really cares about her. He considers her his best friend.
- Ginagi Sayonara: He likes to tease her.

- He's a Jewel Holder.
- The reason behind the gap between the Clock Dimension time and the human time is that the time goes faster in Clock, thus his real age would be unknown since he was in both worlds. His considered age is his physical age.
- Even though he first appeared in May 2017, his first concept was made in around November 2015, however it was scrapped until March 2016.
- There's a recurring gag where the speakers interrupt him whenever he is saying something important, always saying "PriPara pan pon! Mr. Mystery at PriPara Hills / the Headmistress' Office!".
- Likes: Tea, sweets, pocky, idols he finds "exciting", singing, dancing, teasing others, friends, mysteries, chess, videogames.
- Dislikes: Time, pancakes, spicy food, copycats, paradoxes, liars. Also has a phobia of "potential semes" and Haruka's cooking.
- It's heavily implied Mystery likes plushies and crossdressing, but he never speaks about it.
