My Master Says He Doesn't Recognize Me

Zeta has been chasing Zero and calling him "Master" for hundreds of years, and the whole universe has become accustomed to it. Zero said, "You still have 20,000 years left," but secretly he secretly asked Hikari to customize weapons, and even the taste of rice cakes was discovered by his apprentice. Until Zeta rushed into the battlefield alone, and his right arm was torn into light particles. The timer flashed wildly as he hung on the ruins, but what he was thinking about was: "Will Master give me a bigger share this time?" Zero's face was ashen as he rushed into the battlefield. He picked up the broken arm, carried Zeta and left. In the corridor of Silver Cross, Zeta heard him say in the lowest voice: "What a hero." "... You deserve at least one."
