Hmm...we are the first to upload the real ver. of this song. But it got removed within 6 hours, so we upload with more speed to avoid that stupid copyright~
Yes, you could say that they are the same band MrMoro25. The thing is that supercell used to have a singer called Nagi but she opted out in 2011. That year they had auditions to find a new vocalist, and they found two girls: Koeda and Chelly. Koeda sings under the name of Supercell, but when Chelly sings, the band release their songs under the name of Egoist (after the fictional band featured in Guilty Crown).So it's basically the same band, they just change singers.Hope it helps!!! :)
