Sakura Gari

Sakura Gari is a Taishou-era romance story, ten years in the making. It centers on 16-year-old Tagami Masataka as he is aiming to find his place in life. While attempting to start prep school as a rounin, he encounters Saiki Souma, the son of a distinguished noble of the Saiki Koushyaku family, and becomes part of the Saiki household.
It seems as though this will be the story of Tagami's life, taking us through both him growing up physically and emotionally.
