No 4-star character...

I logged in for the first time in a while to accompany my friend's event run, and there was aガチャ for Kanachan, so I did 50 pulls, but all of them were the minimum guarantee. Even if I pull the featured 4-star, there's a chance it won't come, which is pretty rough. I wish they'd either make it a solo banner or improve it so that the rate for my favorite characters is slightly higher...
