While in her fifth and sixth years of elementary school, Aikawa began watching anime and also became aware of the existence of the voice acting profession.
She found it interesting that in some anime series, the cast members would also sing the ending theme.
To hone her skills, Aikawa would often read aloud and made it part of her daily routine.
Her family initially pushed her to pursue a career as a doctor, but permitted her plans to audition as a singer or voice actress.
She applied for an audition held by the talent agency Music Ray'n, and after a series of screenings, participated in a training camp where the finalists would be chosen.
