Akina accidentally turns herself small instead of Hydra when Laine crash lands on her. While she is a little kid she discovers how nice it can be to be a kid. She also manages to confess her feelings for Kazuto to Hydra and Valkyrie and wonders why she is unable to be as genuine and honest when she is an adult. (Source: Wikipedia)
