Touhou 7 - Perfect Cherry Blossom - Perfect Stage 4 Lunatic

A clear of PCB stage 4 without dying, bombing or breaking any borders.
This stage gives a lot of people including me problems.
Here's me figuring out the segment after the midboss, which is a complete trap as you HAVE to kill some enemies or you die and you CAN'T kill some enemies or you die.

Then there's Lyrica's opener.
Here's where the game suddenly reminds you that there's a rank system in this game.
On low rank her opener is completely trivial, but if you have any rank build up whatsoever (like say capture the death fairy) than it will transform into one of the hardest attacks in the entire game.
I don't think that there's any point in the entire game where you notice rank but here.
Not sure how hard Reimu and Sakuya have it here on max rank though.

The Prismriver sisters are a weird bunch to say the least, as they literally have attacks that are easier on lunatic than on normal. Lyrica is by far the easiest (except her bullshit opener) so always go for her. Who you fight in the second part is determined by who you do the most damage to during their first spellcard.
