If you survive that, prepare for some very fast bullet walls followed by more knives. But later, you have to deal with VERY tightly aimed streams of bullets/lasers AND knives she randomly throws everywhere.
Half of her patterns require very fast reactions - she just throws some knives and bullets. While the difficulty of the game is gradually but steadily raised until her battle, she herself is a nasty difficulty spike. Yumeko, the penultimate boss of the game, is known for being a nightmare to defeat even for experts.Yuki, on the other hand, just spams slow and fast patterns, but also uses fireballs that block shots. Mai uses bouncing ice daggers and egg bullets that break into more bullets when your shots hit them. Depending upon who received the most damage, you fight the survivor, and it gets harder. Mai and Yuki, the stage 4 bosses, are pretty frustrating due to the sheer amount of bullet spam coming from two different directions, as well as Mai's laser and small bullets.She is a nightmare to defeat, since she has several attacks that can either spawn very fast spreads of bullets, yin-yangs which are large and bounce off the sides of the play field in erratic fashions, or wall in the player and force them to dodge fast aimed bullets. When playing as Marisa, there's Reimu in stage 4.If you're playing a shot type that can't get around that it'll be a very long fight. She throws it at you in the middle of her patterns, which already require a fair bit of precision, it's slightly homing, and it blocks your shots. She is also aggravating due to her tendency to fly down to the bottom of the screen, much closer to the player than most other Touhou bosses, which makes dodging her attacks harder or impossible. She becomes much easier when the orbs are destroyed. Furthermore, she can cause them to spin around outward in a fashion that is very hard to anticipate and dodge. She pulls out four multicolored orbs that all shoot danmaku in addition to the bullets coming from herself.
