There is a mature soul hidden in her immature body. While she enjoys tennis and family affection as the cheerful and stubborn daughter of the Echizen family, she also transforms into the hacker "DeepSnow", using her past life skills to secretly protect her family, analyze the game, and help others. With two personalities intertwined, she is lonely and struggling to keep the secret. As she grows up on the tennis court, she longs to find someone who can understand everything about herself.
Purpose: Taking Echizen Yukina's two-sided life after fetal transmutation as the core, explore the struggle and growth of a soul with top abilities in the past life when it is placed in a new body, merging self-identities, secretly guarding loved ones, and facing inner loneliness, interpreting the redemption of lonely souls by love and understanding, and the life proposition of balancing self-worth and emotional bonds in the established trajectory.
