Arakune is a black, blob-like creature with a white mask and a playable character. He formerly worked alongside Kokonoe, Tager and Litchi in Sector Seven. He was formerly a human named Lotte "Roy" Carmine. After an attempt to study the link between the Boundary, the Azure Grimoire, and the Black Beast and eventually managed to find a way to briefly enter the Boundary due to his inferiority complex over Kokonoe's genius, he became what he is today, now housing innumerable insects with his now-blobby body and thriving on knowledge. His horrible condition has rendered him virtually insane and lacking any reliable memory, as well as distorting his speech to near incoherency – most of his dialogue consists of gibberish, insane laughter and tortured screaming – but it seems that Litchi and Kokonoe can understand his speech. 

He is very obsessed with finding the Azure Grimoire and wants it for himself, to the point of even trying to consume Ragna multiple times in the story. He had a hard time remembering Litchi when he was human, but slowly regained memories of his life, and started to remember Kokonoe and Relius, the latter being hated by Arakune.
