Ori Sakaguchi

Keito is an idol, a member of the group F/ACE, and has light brown hair parted in the middle and green eyes. He also sometimes wears glasses. He is 21 years old and 1.78 meters tall.

Rintaro is an idol, a member of the group F/ACE, and has straight black hair. He is a handsome young man with a muscular physique and a tattoo on his right shoulder; he is 19 years old.

Natsuki is an idol from the group F/ACE. He has messy blond hair and big brown eyes, and is 20 years old.

Tamon is an 18-year-old high school student who is also an idol in the group F/ACE. He has messy pink hair, gray eyes, and usually wears a hoodie when he's not performing as an idol or at home. When Tamon performs as his "Hottiehara" persona, his hair is styled with a part. However, when he performs as "(Mr.) Gloomyhara," his hair is much messier. Later, when his "Yamihara" side emerges, the difference isn't seen in his hair, but rather in his eyes, which are completely black and often display an insane expression. Sometimes, Tamon tends to be possessive—known as "Darkhara." He is 1.78 meters tall and 18 years old.

Keito has a calm and serene personality, consistent with his idol persona, and is the leader of the group F/ACE. He is described as distracted by Tamon during an interview. Being the oldest member, he tends to appear maternal and caring towards the other group members. He is considered the kindest and most approachable member of the group by fans.

Outside of work, Keito is extremely calculating and manipulative. He doesn't care at all about his fans and sees them as a means to get rich, seeking to become a millionaire and enjoying their naiveté in believing in his public persona, making them easy prey for his own enrichment. Rintaro's stage persona is cold, quiet, and mysterious. A man of few words.

Outside of work, he's a passionate otaku who spends lavishly on his favorite anime characters. He's outgoing and enthusiastic, frequently sharing endless information about the anime he enjoys. Despite this, Rintaro cares deeply about his family.

Like his A-side counterpart, Natsuki has a 'cute' personality and is called an 'angel', with an innocent trait that matches his idol persona.

Despite this, his B-side, or off-duty personality, is notably depressed, unmotivated, and apathetic, choosing to "cope" with the situation by smoking and drinking. It's said that whenever Natsuki gets drunk, he becomes a chatterbox, talking about his personal life and other such things.

When Tamon presents himself as an idol, he is seen as a 'sexy and wild' character, often captivating fans to the point that, when they meet him in person/interact with him, their faces explode or their noses bleed profusely. [ 3 ]

Side B Outside of his career as an idol, Tamon frequently finds himself in a state of melancholy, feeling overwhelmed and in a perpetual state of low confidence and self-esteem, wallowing in despair and listing all the things he thinks he did wrong.

He wants to be seen by more fans, he wants to be loved like Usagi loves Tamon and strives for him, he wants to be popular and hates losing to Tamon. He is the youngest member of F/ACE at 17 years old, while Tamon is 18. He likes cheese tea; he drinks it to calm down.

Ouri is a charming 17-year-old with a "princely" personality, whose goal is to act as a prince to his fans and take care of them.

She has black hair and blue eyes.

Because of his job, Ori has a split personality. When Ouri is an idol, he is seen as the 'Prince' of the fans, often charming them with his looks and promising to take care of them like their 'knight'.

Side B Outside the world of idols, Ouri demonstrates an explosive temper, frequently becoming irritated by situations, other people, and especially Tamon. The relationship between Tamon and Ouri is quite distant; Tamon doesn't want to argue with Ouri, however, Ouri sees him as a competitor and gets irritated whenever he makes a mistake, doesn't try his best, or gives in to despair. When angry, Ouri can become aggressive, even frequently breaking down the door of Tamon's apartment, which causes a lot of difficulty for their manager. (Of course, he never hits Tami directly, only his door, or when he does, it's with a piece of paper fan.)

A significant part of this personality is driven by an inferiority complex. The son of famous celebrities and with a notable name since childhood, he has always lived under high expectations. Therefore, he harbors a personal animosity towards Tamon, as Tamon is the center of attention at F/ACE, believing this prevents his own efforts from being recognized. To make matters worse, Tamon's true personality irritates him even more, since someone perpetually melancholic and lacking in self-esteem has managed to overshadow him. This has led him to aim to defeat Tamon, to the point of becoming arrogant whenever Tamon shows any sign of superiority.
