Tachibana, Keito

Keito is a member of the idol group F/ACE. He's known for his 'calm and collected' personality in his idol persona.

He's the leader, lead vocalist and the eldest member of F/ACE. Keito is popular for his good personality and friendliness. He doesn't show it, but even if discord breaks out among the members, he criticizes them with a harsh tone of concern. Before his debut, he was a coffee shop clerk famous for being too good-looking. He's also a good cook and shows off his culinary skills on F/ACE's video streaming channel.

[Spoiler] His true personality is that of a ruthless miser who only sees his fans as a source of income. He wears glasses in private. In order to make money, he is strict against scandals, and is wary of Utage at first, though eventually comes to accept her as Tamon's emotional support. His intense obsession with money stems from his desire to send his five younger siblings to college and to make things easier for his parents. [/Spoiler]
