I admit I wasn't expecting much from Youmu. I've had some pretty bad experiences with her in other bosses (the Futo fight comes to mind) and the formula on Youmu's NTR nuke (200% ATK - 100% DEF) seems a bit dire when considering the Post-Game's tankiness problem. It turns out she can do okay damage if you properly optimize for it.
She feels pretty similar to Patchouli for this fight. They both need to Concentrate to activate one of their damaging passives before nuking. Their Concentration-centred gimmick also allows them to use Gambler decently enough. The differences are that Youmu uses ATK instead of MAG, and that her damage ceiling is also lower than Patchouli (compare Youmu's 900K vs Patchouli's 1.1M damage).
TBH I wouldn't recommend Youmu for this fight. Unless you're already doing a Youmu-specific run, there's a good chance you haven't been using Youmu at all and she is not a good money dump at this point (though she does improve in later Plus Disk).
tl;dr If you're gonna use a Concentrate/Nuke style attacker for this fight, Patchouli is a lot better.
