That Turtle, The Strongest On Earth

When Bruno was eight years old, he got a turtle from a stall at a festival. That turtle, Ivy, continued to grow rapidly… and eventually became larger than a house. To prevent Ivy from being hunted, Bruno registered himself as a tamer and decided to start an adventurer’s life with Ivy. Wanting to sit on Bruno’s shoulder again like in the old days, Ivy gained the ability to adjust her size… and as it turns out, she was actually the strongest.
