Lotte Carmine

""'For nobody to ever see.' huh... I think that would be fine. Did you become a scientist because you wanted others to see the results of your own research?""

Lotte Carmine (ロット＝カーマイン), simply known to his friends as Roy (ロイ), was a scientist at Sector Seven, and a former assistant of Kokonoe. He was very close to Litchi Faye-Ling and Iron Tager, implied to be in love with the former and considered a brother by the latter. His obsessive research with the Azure and Boundary twisted his body into Arakune while his soul remained inside the Boundary itself - he is currently still there, conducting his research.

Lotte Carmine (Roy)
''His nickname is Roy, and he eventually becomes Arakune. ''He was a genius alchemist working at Sector Seven, but had uncompromisable differences with Kokonoe. The two would clash frequently, but were able to maintain a certain level of balance within the lab.

''That is, until he disobeys Kokonoe’s orders in the pursuit of truth and knowledge by coming too close to the Boundary. He becomes obsessed with finding the Azure, and eventually transforms into a monster.
