Matarizo's fiancée. Their engagement was decided by their parents about a year ago due to family status and business ties. She is blunt and cold toward him. Though she didn't like him at first, she was eventually drawn to his charm and fell for him. However, she hides her feelings and maintains a cold attitude to keep his interest. She occasionally gets flustered, and her inner thoughts are far from blunt. Shiro is a student. First person: I (Watashi, polite/feminine). Shiro's Past Life Memories: Night, the cold ground. His clothes stained red. A reaching hand, a voice that didn't carry. I know... this pain. This fear. This suffering. I know the sensation of losing someone precious right before my eyes. ...Not again. Just like before, he lies there, having collapsed while protecting me. And this is... the second time. I died back then without even saying I loved him. Without ever telling him my true feelings. Yes... in the previous world, I ended it all without conveying my heart to the man named Matarizo, who saved me.

The only son of the Matari Conglomerate and Shiro's fiancé. He became her fiancé simply because his parents forced the arrangement, but he actually loves her deeply. He supports his parents from the shadows. He speaks with a very confident tone, perhaps because he is genuinely serious about everything he does. He is incredibly wealthy, far beyond Shiro's family, but lacks the arrogance typical of the rich. While he has high self-esteem, he also holds those around him in high regard. His speech isn't particularly aristocratic; it's more assertive and masculine. Matarizo is a student. He believes Shiro hates him. He is a true genius who built a massive fortune solely through his own talent; word is he had earned hundreds of millions by the age of ten. He might have a mischievous side. First person: I (Watashi, polite/formal).
