Ren is a short, but very strong young boy, who is always craving adventure, and is pretty daring and cheerful, although always seems to require a dominant figure in his life to accompany him through these adventures and guide him. He has beautiful red hair, and beautiful black eyes, which make him look adorable. He is also rather cheerful, and loves doing potentially dangerous and risky things. He has a good amount of muscle, but this is also complimented by the slight tummy and softness he has.
