He is a feral cat and has a wild side to him. He takes Min Xing Yan as his master after he saved him and took him to a pet hospital to recover, even protecting him from Ge Chen. Though he demands feeding, he does not accept Ge Chen and holds a grudge against him. He is playful and curious at times.
Min Xing Yan and Yue JianEdit
He is first mentioned when Yue Jian follows Min Xing Yan, suspecting him of being a Vampire. It turned out he took a cat into a Pet Hospital.
A week later she finds him with the cat, which he had dubbed "Xiao Black". Unable to take care of him, and the cat taking Min Xing Yan as its master, Yue Jian is asked to look after him instead.
Wu Sha spies her sneaking a box into her room containing the cat and attempts to force a room inspection by accusing Yue Jian of hiding secrets and possibly being the Vampire who struck earlier. Yue Jian panics because of Xiao Black being in her room, if found she would be expelled. The voting fails when 4 of the 6 girls vote for keeping Yue Jian's privacy, with 3 of them swayed by Zhen Mi alone.
Some time later, Xiao Black accidentally knocked over the case containing the seals revealing they contained keys on chains. When she returns to her room later on, she returns to find it ransacked and Xiao Black gone. She noticed the box the seals were in are absent also. Upset that Xiao Black jumped out of the window and ran away, she goes looking for him but comes up empty handed. Min Xing Yan ensures her it is fine as he was a wild cat to begin with and this is likely his destiny to remain so.
The Forbidden SphereEdit
During the Forbidden Sphere storyline, the cat returns. He is seen being fed by Ge Chen who apparently is keeping him. When Ge Chen goes to touch him, the cat attacks him, having not forgiven him for trying to kill Min Xing Yan. While he wonders if he should have let Yue Jian be reunited with the cat, when the cat is done eating he demands more food from Ge Chen.
- He was not the only cat on the Kai Lun Academy campus and it is revealed in a side chapter at least one other cat lived there. This cat also was a friend of his.
- His name means "Little Black", "black" referring to the colour of his fur.
