Being fan of IN I was kind of entertained, though I don't get how he hugged Mystia in her last 2 spell cards. I always thought she fires "fuck off waves" of danmaku if you try to do that. How come I didn't see any here? Or did I miss something?
Those "fuck off waves" as you call them, behave in the same way every time based on Mystia's movement, so he is dodging them. unfortunately, I don't know exactly how they behave in the last spell card, but in the 2nd to last spell card, she only shoots those in the beginning, afterwards you're able to graze the bullets without any hindrances, and it's a fairly easy graze too.
That run it outdated however. Current world record is at over 6.6billion.
