Need help choosing

I tend to pick characters based on their illustrations, or if they're my top favorites even if their abilities aren't the best, so I'd say pick the one whose illustration you like the most haha

Honestly, the performance of Youngnami (the 2nd one) is good, but you really need to unlock SP for it to shine, so I recommend choosing between the first two. (The 3rd one is usable if you force it, but it's pretty bad.)

You don't mean you're using resonance stones for 3 stars, do you...? Anyway, Youngnami is the best, that's true... But please tell me you didn't use resonance stones... I'm really scared...

You gotta pull the same character from the gacha lol. Or else you gotta use resonance stones... Those should be given to limited characters like Fugaa, Jonta, Black Tarte, Black Tōdō, or 0.2 Gojo, who are dealers. Absolutely do not give them to regular characters!!!
