The fusion of Black Goku and Zamasu was too strong, even for them.
By giving me their life energy and hope, the last inhabitants of Earth performed a miracle.
My sword, which had broken during the fight, became an energy sword that ended the fight against Zamasu.
As we thought the threat was eradicated, the spirit of the immortal part of Zamasu spread, becoming the universe itself...
Goku then asked for help from King Zen'o, who not only erased Zamasu but also made my entire timeline disappear... We survived by a miracle, thanks to the time machine that allowed us to safely return to the past.
