Sakura had heard about Xero's expertise in different wild flowers that Xero used to make his poisons that he used in battle. She needed to find a certain flower to use in a medicine for one of her remedies taught by the Fifth a long time ago. Xero knew precisely what she was looking for but had no idea how to find it. He had to travel around outside the village to find it while she was busy finding the other ingredients. Eventually Xero saw a small patch of the small purplish flower he was searching for. Taking careful precautions, Xero gently extracted the flower while causing no harm to the all important root of the plant. Upon returning, Sakura had finished gathering the rest of the ingredients and thanked him for a job well done.
