A mysterious noble black cat with red vertical pupils that appeared in the breeding room and jumped into Xu Xingyuan's arms. It can understand human speech and gestures authoritatively. The Doctor addresses it as Boss and My Lord, showing deep reverence. It drank Xu Xingyuan's blood which greatly stabilized its condition. It awakened earlier than expected, which terrified both the Doctor and Berus who smelled His scent on Xu Xingyuan. The cat wants Xu Xingyuan to become the new Guide. It is described as noble, aloof, and a germaphobe who dislikes being touched casually. If anything happens to it, the entire Infinite Flow world would suffer.
