His mother passed away and he lived with his father-in-law and his younger sister who was in primary school, but his father-in-law ran away leaving a huge debt.
He dropped out of high school and supported his life by working part-time, but since he was a young sister, he stayed with his elder brother Yoshimune who ran a large company.
After more than 10 years of separation due to divorce of his parents, although his real feeling as a brother was certainly weak, Kado, who was told by Yoshimune,' I don't think you are my brother,' was worried and could not hate his older brother even though he opposed it.
