Makoto Kakizaki is a 41-year-old member of the idol group Eternal Boys, standing 181 cm tall with blood type B and born on February 6. Before joining Eternal Boys, he worked in the nightlife industry, debuting in Kabukicho at age 18. He ascended to become the top host at his establishment. Following this success, he transitioned into management, effectively running a host club business until recruited by the president of Manpuku Entertainment for the mature idol project.

Within Eternal Boys, Kakizaki served as the primary lyricist, writing all songs performed by the group. After their first single's release, he departed as a performing member and assumed the role of executive manager. This shift marked a personal journey. His background as a host involved prioritizing others' happiness, often sacrificing his own emotional authenticity. Over time, this led to emptiness, where he recognized his smiles had become hollow and detached from genuine feeling. His participation in the idol project stemmed from a need for self-fulfillment and rediscovering personal joy, seeking internal growth and self-care after years catering exclusively to others' desires, rather than external validation or success.

His name reflects this journey: "Makoto" translates to "sincerity," while "Kakizaki" combines the characters for "persimmon" (柿) and "cape" or "peninsula" (崎).
