Arakune

Summary
A black blob-like creature with a white mask who formerly worked alongside Tager and Litchi in Sector seven. After an attempt to study the Boundary, 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. His dialogue between many characters, as well as his Arcade Mode ending, suggest that it was the power and knowledge he obtained from the Boundary that gradually turned him into what he is, and notably (according to his Arcade mode ending) he doesn't seem to have noticed that he's changed, and to him, his bizarre speech is completely normal. He seems to not understand why others can't understand him, creating a crude mask for himself thinking it would allow others to understand what he's saying. He currently lives in the sewers of Kagutsuchi where the Seithr concentration is highest and will attack anyone who visits there. He has also been known to attack and devour his victims to sustain himself, specifically targeting the Kaka clan, the closest living creatures. He thirsts for power and knowledge above all else and considers the Azure the pinnacle of such. Anytime he meets Ragna he becomes obsessive in his desire to consume the Azure.
