Mashiro Kuna is the former lieutenant of the 9th Division under Kensei. She is a somewhat ditzy girl who is prone to throwing fits for the smallest of things, such as Orihime befriending Hachi or when Kensei insisted on following his subordinates into battle when they were still in the Gotei 13. Her overall style of dress is reminiscent of the costumes worn by the tokusatsu superheroes of late 1970s Japanese television. She often calls Ichigo Berry-tan, a play on Ichigo's name. Fitting with her tokusatsu theme, Mashiro's hollow mask bears a distinct resemblance to an insect's head. She was able to maintain her hollow mask for fifteen hours on her first attempt to control her hollow, meaning she did not have to undergo the same training as the other Visoreds and Ichigo.
