Antoinette (アントワネット Antowanetto) was a type of giant flower used by Milich Oppenheimer at the First and Second Battle at Scarleticia Castle. The flowers were extremely poisonous, capable of leveling whole groups of people who approached them if no antidote were prepared. Unprepared for such an attack, the Toran Liberation Army was quickly routed.
Following the rescue of Liukan from Soniere Prison, an antitoxin was prepared which allowed the Liberation Army to emerge victorious in the second battle. Once Scarleticia fell to the Liberation Army, the flowers were burned and destroyed.
