Neochu is SO much easier without his minion Picochus surrounding him!
This is still a luck-reliant strategy, seeing as how you need Random: Instant Chain to activate. Normally you probably would want to quit come Screech time, but (though you don't see it here) everyone can survive. The bad news is that the stage is not big enough for Lightning to back up and be out of range of Screech, but with triple Sens you can still survive. (Maybe even with the right defensive accessories, though I wasn't too sure what those would be.) The issue, of course, is Pollen, which inflicts a bajillion debuffs. Vanille will prioritize healing red and yellow health over Esuna, so chances are Fang will die (Deprotect + Imperil will kill even a Mediguarding Fang). That's not the bad news so much since she can be revived; it's the second Screech that can kill, depending on how far along Vanille is with healing and Esuna. You could probably spam Potions until Lightning is at full health, then Phoenix Down whoever succumbs to Screech, but you also want to make sure you're taking every advantage to spam attacks against Neochu for the sake of R:IC.
Or you could just get lucky and stagger him before the first Screech. ^_^ I also killed him without a Summon, just to preserve the sanctity of Stage 8 stats (I hadn't realized having the Stage 9 crystarium open would increase the summons' stats; oops.).
