So, I tried out Deltarune on November 1st, and just fell in love with this ax-crazed, chalk-eating, face-chewing jerk with a soft center. So yes, new Best Girl is Susie of Deltarune. She's tough, strong, but clearly, she just needed an honest friend, and Lancer melted her heart. She's got one of the best character development story I've seen in a game, and Toby Fox is a damn genius for creating her.
Now I hope Noelle gets the courage to confess her feelings to her.
