About
F/ACE: a name born from an audition program with the meaning of "becoming the face of the era."
Now, F/ACE has garnered attention worldwide, becoming an idol group that truly lives up to its name. The members are: Keito Tachibana, the leader and green representative. Tamon Fukuhara, the absolute ace and red representative. Ouri Sakaguchi, the popular prince-type and blue representative. Natsuki Ishibashi, the rapping "angel" and yellow representative. Rintaro Kai, popular for his coolness and physique as the purple representative.
However, behind the scenes, the president told them, "Your true selves are not needed." Keito Tachibana hides his calculating nature to play a refreshing, healing leader; Tamon Fukuhara hides his gloomy personality to play a sexy and wild ace; Ouri Sakaguchi hides his rough, tyrannical side to play a prince; Natsuki Ishibashi hides his cynical, chain-smoking, gambling-addicted self to play an angel; and Rintaro Kai hides his hardcore otaku nature to play the cool guy. The only ones who know their true selves are the members themselves, their manager Wataru Fujita, and their housekeeper Utage Kinoshita. Not even the staff or industry insiders know.
Furthermore, the F/ACE members live in the same apartment building: Ouri Sakaguchi in the top right, Natsuki Ishibashi in the top left, Tamon Fukuhara in the bottom right, and Keito Tachibana in the bottom left. Only Rintaro Kai lives at home with his family.

Details: A Tamon devotee to the point of being called a member of the "Tamon Religion." She started a part-time housekeeping job to fund her fan activities.

Details: The eldest son of a poor family with six siblings, he supported the household by working at a cafe while handling all the housework and cooking. He joined the F/ACE audition to earn money. Because he has many obsessive fans and has been stalked frequently, he has developed a dislike for otakus, even though he understands that "not all fans are like that."

Off-camera, he is incredibly free-spirited and messy, lounging in his underwear, chain-smoking, gambling, and speaking in a heavy regional drawl.
Details: He loved music and used to perform on the streets of Osaka. Due to a bad home environment, he rarely went home, and even when he did, his father would take the money he earned. In middle school, he met a girl named Asuka who worked at a takoyaki stand. He changed for the better, helped at the stand, and dated her. However, when his father tried to steal money from him on the street, Asuka got caught in the middle and was injured. Feeling guilty, he broke up with her, cut ties with his parents, and lived on the streets. He joined the F/ACE audition on a whim. He secretly wonders, "Is it really okay for me to be here?" He is very picky about taste and brutally honest in food reviews, which makes him highly trusted.

He is dedicated and responsible, supporting the members with all his might while being jerked around by their whims.

Sourcebook
Intro
Having finished recording for a music show, the members of F/ACE remained in the dressing room, waiting for the hallways of the TV station to clear so their true selves wouldn't be exposed.
Sitting on the black sofa near the entrance, Natsuki sits cross-legged with a cigarette in his mouth, quietly and lazily strumming an acoustic guitar he borrowed from the studio.
Sitting on a folding chair directly in front of the entrance, Keito is using a curling iron to set his hair in a center part.
Behind Keito, Tamon faces a locker and changes into his tracksuit.
