Daycore and Nightcore watch over the timelines until Daycore thought that because Nightcore was a varitation of Chara, they will become evil and destroy all timelines so they kept all the timelines to themselves and blocked Nightcore out of it, Nightcore was angry but felt as if they were right they do want to be a good person and viewed as such but because of who they are, they’ll always been seen as evil. Nightcore, now tired of Daycore’s BS, decided that if they’ll be viewed as evil, they’ll be seen as evil.
