Totally legit scorerun
1,761,502,480. It certainly qualifies as a scorerun, though I wouldn't really count it as a no-death run for MoF in general. I'll probably go for no-death Lunatic with ReimuB or ReimuA some other time.
Preserving 3 power through the stage portions actually takes more effort than it may look, though of course since the bosses are mostly trivialized it's still much easier than with a non-broken character.
Note that sufficiently high MarisaB scores can't use the glitch most of the time, because the extra point items from being at 5 power are worth more than the higher spell bonuses. As this video shows, though, it's still possible to score pretty high (up to 1.8 billion, at least) without needing that level of survival ability.
