Rate the designs! I used this chart for it.
https://tiermaker.com/create/hololive--180517Remember: their initial design only! For example: while I think shion's initial design is rather poor her gothic lolita one is definitely A+ - S tier. I think it made it easier to rank them but I guess you can do it however you like. I like Ollie's design and Reine screams 'sex' so they are both S rank.
