So my idea for how to deal with Anri:
Get Oriko to Social her. Talking is something Oriko does better than meguca'ing; meanwhile, Anri already hates our guts, so Oriko should have a better chance to talk her down.
Now, the thing is, after reading Sadness Prayer, I have remembered and had it thoroughly rubbed into my mind that Oriko. Absolutely. Sucks. At. Combat. Garbage tier.
Oriko is slow; probably slower than Sabrina. Her attacks don't do much damage in comparison to other megucas' attacks, nor do they travel that fast, nor can she spam. Without her powers... sending her to Social Anri without Kirika to protect her would be retardedly dumb bad stupid.
Thing is, still, there's not that much Kirika can do to protect Oriko if Anri turns violent. Well, we'd Gem Anri if she did, so hopefully that's OK.
Now, keeping in mind that talking Anri down might be an impossible task... maybe we should just Gem her, as some people already want to do.
