He has ginger hair and amber eyes.
He is called the "evil" twin. Even though both can be really devious. Hikaru comes up with most of their tricks and pranks. He is also less mature than Kaoru and very childish. He seems to be very protective of his brother and sister. Him and his brother often get into trouble together and are rarely found separated. If you separate these two, Hikaru gets separation anxiety and panics.
He is from the anime Ouran High School Host Club.
He doesn't really have any weapons nor powers, but it seems he can easily rip open someone's chest. Even if that someone is made of a material that is stronger than diamond.
