Lenen Evanescent Existence - Unreal Stage 1 No-miss No-bomb No-flashbomb (Tsubakura)
4I'd initially thought that this would be the only stage in EE that I'd be willing to get an UNNN for.
Turns out, I'm able to go a bit further...
The stage portion is all about killing things ASAP, as with just about all Len'en stages.
Kurohebi midboss nonspell (NS): The knives are aimed, and the bullet pairs are random. Stream carefully.
Darkness Card "Melanistic Shot"
Stay at the bottom. The bullets are revealed as they approach you, so make small, decisive movements down below.
Strong-willed Shadow, Kurohebi:
NS1: The masses of knives are shot at you. They come in four waves of increasing width. You want to side-step the whole mass for the first two waves, but after that you can just make a small tap left/right to let the 3rd and 4th waves pass by you harmlessly.
Slash Card "Slit Dragon"
No particular strategy other than getting good/lucky. Don't hug the bottom, lest a stray bullet from below the screen pokes your butt.
NS2: It's simple dodging. Don't panic.
"Imperceptible"
It's simple dodging, but with less reaction time, since the knives are revealed moments before impact. Stay calm, and end the attack ASAP.
