Nobunagun
Shio Ogura is a Japanese high school student, who is visiting Taiwan on a school trip when she is suddenly attacked by monsters. Agents known as "E-Gene Holders" from the government agency DOGOO also arrive, who wield weapons infused with the spirits of historical figures. Shio is revealed to also be an E-Gene Holder when the soul of Oda Nobunaga awakens after she tries to rescue a friend. (Source: Wikipedia)
