SPOILERS:
So MC went back in time, killed Kazuma before he ever committed genocide, then slept in waiting. He then collides into the real MC in the present, along with Gekko and sends both of them back to restore balance. But since he went back in time, he replaced the MC that went back in time and came back to the present?
TL;DR
MC timeline: Travel back in time, sleep to present and meets MC of that timeline, sends MC of second timeline to the past, and this loop infinitely continues...
However, the story was very confusing at times, would recommend trying it out. Plot twists are strong as well
