I love the designs in this game. Was originally bummed when my Switch had to be replaced over X-Mas, and I lost my original save file. However, having watched a video on pulling rare blades, I have been able to really increase my luck and in Ch6 have Boreas, Zenobia, and Ursula, and began stacking dark to pick up Vale.
Favorite designs are Herald, Ursula, and hopefully soon KOSMOS. Finch and Boreas are the coolest characters though. Love the heart-to-heart where Boreas talks about licking Tora for "just a taste", as opposed to eating him since he's a friend
