Born a fisherman's daughter, Onuma Akiho grew up surrounded by nature until she moved to Tokyo in order to attend a bridal vocational school; the reasoning being that she wanted to help make people happy on their marriage day. She later joined and passed Sakamichi Joint Audition, becoming a part of Sakamichi Trainee until she was assigned as another colorful addition to the group. Akiho's "dynamic movement" and unique remarks quickly showed itself and left a strong impression to both members and fans, resulting in even more candid moments during TV and radio programs. But she is not just funny and interesting, Akiho is also earnest and hardworking in all her doings-- or rather, she only knows 0% or 100%. Will you also get caught in her world?
