Kuki Mamoru calls Kudou Retsu, "sensei".
Appearance and Personality
The Families that bear the number Nine (九) in their names work together better than others.
The relationship of the Ten Master Clans to the 18 Assistant Houses is like Main House to Branch House. Another comparison is of that of a Lord to his retainers.
They could be called a "traditional faction", yet the truth of the fact is they work together with the Kudou Family against mutual enemies. This makes the Kudou Family the "core", when referring back to the Ninth Institute. Rather the reason that they were the core instead of the heads of the Kuki and Kuzumi (九頭見) Families is due in part because of Kudou Retsu's charisma.
Although Retsu's influence has waned over the Ninth Institute, but the former heads of the Kuki and Kuzumi families still recognize him as their leader.
