When Zeros and Ace pursued the enemy Baraba to the moon, Zeros, Ace's other adopted son, worked with his squad to defeat Baraba. He didn't know that the true enemy was the Evil Eliminator, which survived by attaching itself to Baraba and absorbing malice. Controlled by the Evil Eliminator, Baraba launched a sneak attack and killed two of Zeros's teammates. Enraged, Zeros pushed beyond his limits and detonated his own body, taking Baraba down with him. In the end, after his energy ran out, he became an ordinary young man named Luo Chuan and fell to Earth, landing at Muzan's spawn point.
