Description
Gaku Yaotome is a twenty-two-year-old idol who serves as the leader of the popular idol group TRIGGER. He is the son of Sousuke Yaotome, the president of the major entertainment agency Yaotome Productions. Physically, Gaku stands 183 cm tall and has grey hair and grey eyes, with his image color being grey.

Gaku presents a public image that is often cool and intimidating, and he has a reputation as a playboy. This has led to him being voted the number one man that women want to be embraced by. However, this persona is largely for publicity, as his true personality is much more sincere and principled. He is known to be straightforward, honest in his actions, and deeply passionate. He has a strong sense of justice and dislikes illogical situations or people who do not value their families.

His family background has a profound influence on his character. His parents divorced when he was young, a result of his father's lingering feelings for another woman. As a consequence, Gaku harbors resentment toward his father but maintains a close, secret relationship with his mother's side of the family. He even works part-time delivering soba for his maternal grandfather's shop, a fact unknown to most fans and acquaintances, who mistake him for a lookalike. This experience has instilled in him a deep respect for familial bonds.

In his role within TRIGGER, Gaku is the de facto leader. The group was formed when he, along with Tenn Kujo and Ryunosuke Tsunashi, was brought together by his father's agency. Their initial relationships were rocky, with Gaku and Tenn frequently clashing, but they eventually found common ground in their desire to protect the integrity of their group. Despite their continued quarrels, Gaku is fiercely loyal to his teammates and trusts them implicitly. He is strongly opposed to using underhanded tactics to gain an advantage and has openly rebelled against his own father's unethical business practices to ensure fair competition for rival groups like IDOLiSH7.

Gaku's motivations are driven by a desire to succeed on his own merits rather than through his father's influence. He is a hard worker who believes in earning his place through talent and effort. His development throughout the story involves reconciling his public persona with his private, more authentic self. He becomes an unofficial supporter of the idol group IDOLiSH7, partly to spite his father, but also because he genuinely appreciates their talent. Through these interactions, he develops a romantic interest in Tsumugi Takanashi, IDOLiSH7's manager, making several attempts to spend time with her, though his advances are often complicated by their professional circumstances.

Beyond his professional skills as a talented singer and actor, Gaku has a few notable abilities and habits. He has a driver's license and enjoys driving, learned to play the guitar for a drama role, and is a connoisseur of soba, his favorite food. He also has a quirky habit of sending riddles when he is feeling depressed.
