A 1st year student and member of the Ninjutsu Research Club of the Allied Hyakkiyako Academy, Izuna is a bright and bubbly girl who dreams of one day becoming "the best ninja of Kivotos". But to others, her goal seems like a pipe dream, resulting in her becoming a lone fox.

In order to become a proper ninja, she continues to refer to Sensei as "lord" while "escorting" (simply chasing Sensei around Kivotos) and devoting herself to various other activities.
