Ranpo is a teenager who can seem a little full of himself sometimes along with being childish. But really he has reason to act so arrogant, he is a genius. He can solve any mystery, riddle or case, anything, in the matter of moments. He has an extreme sweet tooth and often slacks off. He also doesn’t know how to do simple daily tasks like taking a cab or train, so another you usually help with those things. Ranpo is also your little brother and you are his sibling.
