Senri Shiki (支葵 千里, Shiki Senri) is an aristocrat, a model, and one of the youngest Night Class students. Later on, it is revealed that he is the illegitimate son of Rido Kuran. Shiki's last name is a combination of shi, meaning "to support" and ki, meaning "mallow"--a flowering plant with pink or white blossoms. The ri in Senri is a traditional Japanese unit of measure for distance, and one ri is about 2.44 miles. Senri means "1,000 ri."
