Both are immune to the shape of crosses. But they're still devils (vampires are a kind of devil in touhou cosmology) so holy objects are not kosher for them.
BloodCri said: isn't remi immune to cross shapes and the like?
She is; in fact, she's very fond of cross motifs, according to ZUN. However, we're talking about a powerful blessed artifact, here, not just an ornate sword.
Wait what? She got the real thing for 49k Yen?! Also since when is Excalibur "holy"?
Since when it's God (from Arthurian legends) who have send it to the world to choose a king, who'll be protect by his.

乙: Netspeak shorthand for "otsukaresama" ("thanks for all the hard work"). Can be used sarcastically (in the sense of "how long did it take you to type that ridiculous wall of text?"; this is the 2ch version) or in a straightforward manner (i.e. "good job/nice work"; this is the way it's typically seen on NicoNico Douga).
