Sol's bad ending''Accent Core.'' In both endings, he is transported back in time by I-No where he fought his younger self, Ordel Sol. After the fight, I-No kills his younger self. Actually, it makes you wonder in the first place why Sol just fought a lookalike without thinking. In the bad ending, where Sol dies, why would you die if your younger self dies? Then who fought your younger self? Why did you exist in the first place?
Order Sol: I'll crush you!
