Akitsu

Akitsu, is a 'disused' Sekirei; Homura refers to her as 'Scrap Number'. She can't be winged by an Ashikabi or use the Norito (she is useless from MBI point of view). Akitsu's power is very strong, allowing her to fight on par with Sekirei like Homura (they have encountered each other 3 times so far). Despite the fact that she can't be winged, she considers Hayato Mikogami her Ashikabi because he took her in and she fears being thrown away again.
