Sara is despondent and angry when Fujita hires a young woman, Tsujido Luna. She wants to train as a painting restorer at Gallery Fake because of Fujita's high reputation. While looking at a repair problem of "art cancer", the formation of white crystals unique to Japan, Fujita discovers that Luna is the daughter of the famous restorer Tsujido Naoyuki who recently passed away. Her father respected Fujita's skills, but said they were being wasted. She continues to study with him even though he is hard on her and very demanding. Slowly she develops a newfound respect for his skills and technique, and eventually he teaches her how to repair "art cancer". She then uses the technique to restore a damaged Delacroix painting owned by her father to pay her family's debts. Luna then leaves Fujita and obtains a job at a fine arts research center. However when she tries to sell the restored Delacroix painting, there are few buyers. Fujita decides to buy it at a lower price than being asked, calling the discount a lesson fee.
