What is this gacha luck...⁉️

At the RikoFes, I somehow got Shiho (Pure, permanent card) who I hadn't had for nearly 6 years, and then Mysterious Ena, so now I have all characters and all types of 4-stars fully collected～～～💪💪 Or so I thought, but then I also got the rate-up Len in the event gacha⁉️😲 I was aiming for Luka and Kaito, but I'm still genuinely happy about this~! 🙌✨
