Who is Blood_Of_Damocles

With that Bernard was out of the game since his time was already up, but then compared to before both his energy and stamina points did not become zero because he literally didn't have the chance to use any of them like he had planned to, so he was able to leave by himself without needing to be killed by his opponent. After leaving, Amaka was immediately teleported out of his match by the game system, however throughout the process of her leaving she only had one thought in her mind and that was.

Was the user Blood_Of_Damocles two people sharing the same account? Or was he just a single person? And if he was just one person what then was his symbiote bloodline?

This wasn't just a mere thought, but a question that wouldn't go away and was stuck to her mind, like a sore thumb.
