These are my opinions not just on the alt solos and cards, but also some thoughts about each character's voices only. There is some bias because I like some characters more than others. Also, sorry to whoever I will upset because they disagree. Leave those disagreements in the comments respectively! Hope to make more videos of other Project Sekai stuff and other things! (This is a reupload, my dumbass forgot to move Mizuki's stickers so that's actually there now. Whoops!)
