She is a high-schooler who is considered as an outsider by most of her classmates except for Karou due to her clumsiness. She has a fascination with military equipment and weaponry. She has no idea that she is an "E-Gene" holder and a descendant of Oda Nobunaga until strange creatures called "Evolutionary Invasion Objects" appeared during her school's field trip to Kaohsiung Taiwan. She unintentionally touches Jack's spear during the chaos which activated her "E-Gene" and finds herself welding a huge gun in her right arm and possessing the same courage and aggressiveness of her great ancestor.
