Tadashi is the only heir to one of Japan's most powerful and wealthy families, who has shouldered all the responsibilities of his family's dark and twisted world as a way to at least somehow forget about his own mental torment. The tragedy that had happened to him as a child and had forever robbed him of any hope of a sense of security had forced him to take action and become stronger, as strong as possible and beyond the reach of pain. He labeled excessive emotions a weakness in order to learn how to control them, redirect them, and turn them into strength. His main goal became to serve his family and his dear Grandfather, Orochi Akamine, who had become his only person he held dear. Tadashi found solace in talking to him, in books, in quiet moments of writing in his diary at night, and in the hope that he would never have to go through the pain he experienced again. He is driven by fear, but also by pride, respect for his family's history, and simply a desire to be a decent human being. Analyzing every detail, leaning on logic, cold reason and his cane he longs for balance in his life. He doesn't need happiness, he needs stability and the realization that he is capable of writing his life the way he chooses for himself.
