A secret diary kept by Ichijou Masaki, the eldest son of the Ichijou
family and the next family head. Known as the "Crimson Prince" as a
result of the New Soviet Union's invasion of the island of Sado, he was
a student of the Third High School.
This diary was composed of his uniquely genius thoughts on advanced
magic theories that he came up with between his studies, tactics for
magical warfare, thoughts about the future of the Ten Master Clans, and
more... or so the rumors go.
Thanks to arrangements made by his father Gouki and Principal Maeda
of the Third High School, he is currently attending the First High
School, where Tatsuya and Miyuki are enrolled. For this reason, it is
thought that the incidents occurring there are also recorded within his
diary.
Incidentally, even his best friend Kichijouji Shinkurou nickname
"Cardinal George", does not know of its existence.
