Tobu Railway's 5th Locomotive Raillord shes a bug loving Raillord who's lazy and has no willpower, but as she was so pure in her simple-mindedness, she was still liked and kept on the line. However, as more and more people left the company due to the great railroad depression and the financial crisis of the company, she was forced to realize how childish she was. Thinking, "Now it's my turn to return the favor to everyone," she honestly strives to grow. But if she sees a rare bug, she completely loses sight of everything but the bug.
