Sento, home of the Sento-Saiyans (a subspecies of Saiyans). Sento-Saiyans are mostly different in appearance to Saiyans, having yellow or orange irises and a more hairy body but very different in behavior. Saiyans are aggressive, hostile, and generally barbaric. The Sento-Saiyans, despite being more primitive, are actually very calm creatures, though they can get aggressive and hostile quickly if provoked, but they're mostly just curious of you. Their look is also based on Super Saiyan 4.
