Kurokuma is a stuffed robotic bear that appears as an ally to Warriors of Hope. Kurokuma has a gangster-like, obscene personality. He swears often and has an impatient, immature nature. He is very immoral and has a rather dark, vulgar sense of humor. Some of his jokes are references and more clever, while others are simply immature or just bizarre. He is also very brash and disrespectful, even towards people he just met. He isn't above cheap insults or provoking. He is incredibly noisy and loves to talk, to the point where other characters find him very annoying. At times he speaks extremely fast, too fast to understand him. He claims that talking is his whole purpose in life, and he would die if he stayed silent for too long. Kurokuma is very arrogant and is the only one who finds himself even remotely funny. He believes he's a very talented rapper and entertainer, which is obviously not the case.
