After Roto regains his regular ID, Yureka remains present. Her presence is yet to be explained, but she is likely a rogue AI. It's possible she was hacked, given that all her stats are maxed out—an oddity since her proficiency with specific spells and weapons is zero. Regardless, she possesses a unique ability to mimic enemy moves used against her and retaliate with more potent versions.
Her true identity is that of a programmer/hacker named Jaeha, whose goal was to kill someone just to prove she could become a murderer. She asserts that Roto/Lotto compelled her to become a killer due to her jealousy towards her own AI, whom she aspired to be but couldn't because Roto/Lotto once told her she wasn't the Yureka he knew.
