Homare Katsura, a 20-year-old college student, balances academics with his role as the keyboardist for the idol group JAXX/JAXX. Living in a shared house with five roommates, he naturally assumes responsibility for meal preparations, showcasing his compassionate and supportive demeanor. His striking pink hair and eyes complement his lean 1.76-meter frame, 56-kilogram build, and blood type A, with a birthday on September 13.

The hiragana-written name Homare (ほまれ) hints at nuanced kanji interpretations—such as "reputation," "praise," or "hope"—while his surname, Katsura, evokes the elegance of the Japanese Judas-tree. Soft-spoken and attuned to harmony, he prioritizes teamwork and fosters camaraderie within his group, subtly nurturing relationships through quiet dedication.
