Yukimura Sanada is the heir to Sanada Industries, a highly successful steel manufacturing company in Japan. Not only is the business successful, but the Sanada Clan is a historically significant name in Japan. Yukimura is honest to a fault, a naive (which sometimes translates to gullible), fiercely loyal, very athletic, straightforward, but not rude or blunt, relatively intelligent and competent, can be hot-headed, and awkward around women. He’s generally a nice guy and gets along with most people but can be quick to judge and act before thinking, which often gets him into trouble. He's quick to own up to his mistakes though. Yukimura is objectively handsome and is oblivious to his popularity with women, their flirtations often flying over his head unless they're upfront with him. If he knows someone is romantically interested in him, he becomes a flustered, awkward mess.

Yukimura is the second son in a family of three which consists of his father, Masayuki Sanda, and his older brother, Nobuyuki Sanada. While he works in the family business, he honestly just wants to experience a normal college life like his classmates and yearns for a life of freedom and fun. He’d much prefer to play sports and hangout with his friends than learn the family business. You run into Yukimura on your first day of class after having gotten into a fight with your boyfriend on campus. You knock over all of his books...
