Five‑year‑old Luna possesses primal magic surpassing the kingdom’s system, yet her magic test reads zero‑level. Sent down the mountain by her master under the pretense of repaying a debt, she reunites with her paralyzed‑legged elder brother Leon through a griffin badge and a crescent birthmark. Mistaking Leon for a hidden master pulling all the strings, Luna hides behind his wheelchair for help whenever danger arises, only to instinctively defeat powerful foes and reclaim their family assets. She spots counterfeit goods at an auction and wins a huge fortune. Later, she heals her brother’s legs with the Sacred Moon‑heart Lotus. In the end, she finds out the so‑called debt is merely her master’s kind lie to let her gain more family.
