Sonnenblume's disposition is just as bright and friendly as the flower he's named after. Patient and well-behaved, he is easily handled and generally gets along with human and Tokota alike. Despite his easy-going personality, however, he is quite disciplined when it comes time to work, and loves nothing more than to please his (rather strict) handler. He was trained since puppyhood to recognize and seek out certain plants by scent, which his handler uses in various medicines and remedies.
