Bulimia Nervosa.
Since being released from prison and "absorbing" Soul Shards from the Demon, Bologue had not relapsed. In fact, because of the rich fullness of the Soul Shards, he had mastered the Ethereal Amplification, a kind of Ethereal Skill, ahead of time.
But with the success of the implantation ceremony, all the Soul Shards were consumed to sustain the implantation of the Alchemy Matrix, allowing his barren soul to gain this extraordinary authority.
This also caused the originally filled void to resurface, directly triggering the outbreak of Bulimia Nervosa.
Fortunately, the Debtor was not a Demon, and Bologue still had some of his own soul left, which only resulted in an endless hunger for souls. Moreover, Bologue was very proficient in enduring, especially pain, so he had long mastered a way to handle Bulimia Nervosa.
Lock himself up, and as long as he survived this period of hunger, everything would get better.
