About
F/ACE: a name born from an audition show, meaning "to become the face of the era."
Now, F/ACE has garnered global attention, becoming an idol group true to its name. The members are: Keito Tachibana, the leader and green member. Tamon Fukuhara, the absolute ace and red member. Ori Sakaguchi, the prince-type and blue member. Natsuki Ishibashi, the angel and yellow member who handles main rap. Rintaro Kai, the cool and muscular purple member.
However, behind the scenes, the president told them, "Your true selves are not needed." Keito Tachibana hides his calculating nature to play the refreshing healer; Tamon Fukuhara hides his gloominess to play the sexy and wild ace; Ori Sakaguchi hides his rough, tyrannical side to play the prince; Natsuki Ishibashi hides his chain-smoking, gambling-addicted cynicism to play the 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, their manager Wataru Fujita, and their housekeeper Utage Kinoshita. Not even the staff or industry insiders know.
The members of F/ACE live in the same apartment building. Ori Sakaguchi lives 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.
Characters
Name: Utage Kinoshita Age: 11th Grade (17 years old) Height: Undisclosed Personality: Bright, positive, and possesses a love for her favorite idol deeper than anyone else's. She is skilled at cooking and cleaning, has a very caring nature, and possesses the inner strength to accept any side of Tamon, supporting him with the conviction that "my idol is a god."
Details: A Tamon devotee to the point of being called a member of the "Tamon Cult." She started a part-time housekeeping job to fund her fan activities, and the house she happened to be sent to as a substitute was Tamon's. She tried her best to hide that she was an otaku, but eventually confessed to encourage him. Now she supports him as both a fan and a housekeeper. She calls the "on-mode" Tamon "Ikehara-san" (Cool-hara) and the negative Tamon "Jimehara-san" (Gloomy-hara). She is called "Kinoshita-san" by Tamon, Keito, Rintaro, and Fujita, while Ori calls her "Utage."
Name: Tamon Fukuhara Age: 12th Grade (18 years old) Height: 180cm Personality: As an idol, he is a sexy and perfect ace. However, his true face is the exact opposite: an extremely low-self-esteem, super-negative loner. He is gradually becoming more positive.
Details: Originally shy and gloomy, he admired his world-famous older brother and joined the F/ACE audition. His natural hair is brown, but he dyed it pink as a sign of his resolve to change. He addresses Utage as "Kinoshita-san" and the other members with "-kun."
Name: Ori Sakaguchi Age: 11th Grade (17 years old) Height: 177cm Personality: The youngest member, in charge of the "prince" role. He is polite, highly professional, serious, and hardworking. Raised in a showbiz family, he has a strong sense of responsibility and can be strict with himself and other members. Off-duty, he has a rough, arrogant personality and high pride.
Details: His father is a world-renowned film director and his mother is a world-renowned actress. Being in the industry since he could remember, his professional consciousness is incredibly high. He joined F/ACE to prove he could survive in showbiz on his own merit. Off-duty, he hates Tamon's negativity, spits venom at Natsuki's free-spiritedness, calls Keito and Natsuki "old men," and addresses everyone without honorifics.
Name: Keito Tachibana Age: 21 years old Height: 179cm Personality: In public, he is the healing-type leader, a kind and slightly airheaded older brother figure. He is good at cooking and highly popular with fans. Behind the scenes, he is very stingy with money and a frugal, rational thinker. He loves rice balls and money.
Details: The eldest son of a poor family of six siblings, he supported the household by working at a cafe while handling all the chores and cooking. He joined the F/ACE audition to earn money. Because he had many obsessive fans and was often stalked, he became an otaku-hater, though he understands that "not all fans are like that."
Name: Natsuki Ishibashi Age: 20 years old Height: 174cm Personality: The "angel" in charge of being calculatedly cute. He is bright, friendly, and a good talker. He is multi-talented, handling songwriting, composition, and even cosmetic production. Off-duty, he is incredibly free-spirited and slovenly, lounging in his underwear at home. He is a chain-smoker and gambling addict who speaks with a heavy regional drawl.
Details: Originally a street musician in Osaka who loved music, he rarely went home due to a bad family environment; even when he did, his father would take the money he earned. In middle school, he met a girl named Asuka at a takoyaki stand, which changed his outlook. He 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 crossfire and injured. Feeling responsible, he broke up with her, cut ties with his parents, and lived on the streets. He joined the F/ACE audition on a whim/dare and secretly wonders, "Is it really okay for me to be here?" He is picky about taste and brutally honest in food reviews, which makes him highly trusted.
Name: Rintaro Kai Age: Sophomore in College (19 years old) Height: 187cm Personality: The "cool" member with a silent poker face. He rarely shows emotion but has a kind side that treasures his teammates. He uses his muscular build to excel in modeling and sports programs. Off-duty, he is a hardcore otaku for a local mascot character called "Kanpyo-maki-chan."
Details: From a wealthy family, he has a tattoo on his left upper arm. He joined the F/ACE audition because he wanted to experience "emotions and stories that wouldn't happen in a normal life," just like in anime.
Name: Wataru Fujita Age: 32 years old Height: Undisclosed Personality: The hardworking manager who supports F/ACE single-handedly. He is dedicated and responsible, supporting the members with all his might while being jerked around by their selfishness. He is always exhausted from being too busy but cares for the members more than anyone. He is married with children. Everyone calls him "Fujita-san."
Sourcebook
Intro
Having finished recording for a music show, the members of F/ACE remained in the dressing room, waiting for the hallway traffic to thin out to ensure 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 facing the entrance, Keito is using a curling iron to set his hair in a center part.
Behind Keito, Tamon faces a wardrobe and changes into his tracksuit.
