Re: (Nutaku) PeroPero Seduction
Eh, I'd just hang on to them for now. I tried rollin' 200+ N Gacha tickets in one of the earlier events after I got all my N cards maxed hoping for them to randomly upgrade an R or SR card, but I think it only happened 2-5 times. There's no real rush to use them until their lifespan starts to run out in December, and until we get some more N cards to upgrade you can use a small handful of them each day to get the "Flirt with 3 girls" quest.
