I just lost a DDC Lunatic No-Focus 1cc with ReimuB, so badly that I decided to just stop trying... why? because I realized that the clear would go like this:
1. restart 20 or so times thanks to Cirno's spellcard
2. decide to just screw it and bomb it along with Waka's first spell (and probably the other one as well, since she moves too much and it gets obnoxiously long)
3. have stages 2 and 3 be the only ones I do properly, and get a decent amount of lives... to just bombspam through Kagerou
4. use stage 4 to recover from Kagerou's fight and die Yatsu to at least 2 times (having used every bomb available)
5. have a regular stage 5 that goes downhill after midboss Seija, and guess what? bombspam through the boss
6. I don't think it's necessary to say how Sukuna would go...
So yeah, even if I could clear this, I wouldn't be happy to get it, because just bombing through everything is something I don't like doing, and defeats the purpose of the "challenge" I intended this to be
