In the past, Zhang Taishang received a letter from someone who didn't know who asked him to meet at the Moonlight Bar. It turned out to be Maeda Yukiko!Asking Zhang Taishang to apologize for ruining her husband's funeral with a bomb and injuring her. Her sincerity towards Zhang Taisang in the past was only insulted, but Zhang Taishang believed that friends do not ask for anything in return. Anyway, now in JapanThe era has ended, so Yukiko Maeda wanted to return to her country quickly, but she didn’t expect thatMaeda Yukiko came here to destroy Jin Yutang, all his family and friends, and Zhang Taishang. However, in the end, Maeda Yukiko gave Zhang Taishang the most terrifying gift "Naren", hoping to make Zhang Taishang miserable for the rest of his life.So when Zhang Taishang began to turn into a monster, he hunted the Naoyue clan with his own hands!

Back to the present, when Maeda Yukiko saw Yin Caiyu, she knew that it was the teacher who allowed her daughter to survive. She also felt that Yin Caiyu should thank them for their actions to survive, but Yin Caiyu accidentally learned that Zhang Taeshang had also been experimented on!, now Maeda Yukiko wants to take revenge on Yin Caiyu, so she throws her into the experimental field and looks distressedly at Zhang Haozai covered in blood!In order to save Yin Caiyu, Zhang Taishang chose to become a Naren again regardless of Yin Caiyu's stop. Although these memories are full of sadness, they also include memories with Yin Caiyu.Zhang Taishang became a host, awakened his abilities, and immediately wanted to find Yin Caiyu. On the other hand, Yin Caiyu, who was extremely sad, also boldly activated his abilities in order to find Zhang Haozai.Maeda Yukiko was very calm and unhurried. All she had to do was bring Zhang Taishang to her side and ask to get rid of Yin Caiyu~ Katsuzo suggested that it would be okay to release the child No. 71 who was in good condition to deal with Zhang Taishang, but in the end it was Kuroko who was releasedthem.Yin Caiyu and Zhang Taishang annihilated two teams of black men. Sheng Zao pretended to be injured so that Zhang Taishang could lure other black men to the No. 5 corridor to have a chance of winning. It also allowed Yin Caiyu to stay in place to let the wounds recover, and finally allowed the two to reunite outside..Of course, the organization knew that Katsuzo helped the two of them ~
