>>7931125The lasers on her nonspells have weird hitboxes which start and end like a second after their sprite appears/dissapears so keep that in mind. Generally you dont want to move during that nonspell much, the phase where she shoots bullets at you in radial direction and moves all over the screen especially since the bullets are aimed straight at you and by moving erratically you`ll fuck the pattern up and get walled in.
Also which shottype do you use and are you talking about midboss Sakuya or stage boss Sakuya.
>>7931135IN is easiest with Barrier team maybe, other teams have a pretty hard time on lunatic, like Keine is way harder than Alice, Reimu or especially Marisa are again WAY harder than Prismrivers which i never had any troubles with on lunatic, 5th stage is a joke in PCB if you`re able to memorize it well, i`ve used to perfect the stage part pretty often, Youmu is kinda harder than Reisen though, i`ll give you that, 6th stage has the tardspam in PCB which is again pretty hard, but Kaguya/Eirin is harder to deal with that Yuyuko absolutely, she has like two hard spells for me being the second one and the survival one.
