A young girl is struggling with something she cannot name. After meeting Marie Kondo, she finds the language and the courage to face it — to listen to the voice she had been ignoring and begin finding what genuinely matters to her. The story is told in visuals that read like a picture book, appropriate for all ages. From the beginning of her journey inward, the girl begins traveling outward as well, meeting other people across the world who are carrying their own burdens. With help from Marie Kondo and the Mononoke spirits who join them, she helps others find their own version of what she found — the joy that comes from clearing away what does not belong.
