Amiya is so ridiculously cute it amazes me how much I love her. It also helps that even her personality is fantastic, and the amount of great art she gets from the fanbase makes me happy.
The fact she isn't in Endfield is an absurd thing to happen, even though it does makes sense considering it's in the future and all that, but it still doesn't feel right that the face of Arknights isn't in there.
No matter how much I love some of the other characters in the game, I always end up returning to Amiya no matter what, god bless our supreme leader.
