Yakov Nikitin

A man with the appearance of an elderly Russian. Blood type O. Formerly a doctor. The only person to have stayed at the station twice. He was aboard the space station with his wife, Darya. His catchphrase is "Oho!" and one of his descendants, Kaseki, shares the same catchphrase. According to his wife, he has a loud voice but a timid heart, and he was flustered when Lilian acted in a high-handed manner, but was relieved once he realized it was an act. After returning to Earth, he had children with his wife, but when Connie contracted pneumonia, he and his wife went by boat to the mainland to fetch antibiotics but never returned. During the glass record-making initiated by Byakuya, he and his wife provided their diamond wedding rings for the needle to engrave the glass. Despite his timid nature, he possesses high research capabilities.
