Because I've seen the OVA and read the script from Materials and nothing of the sort happens

Original Novel material

What novel?

Why isn't this on her page?!

That's why I'm asking, I've checked every source on her page and there is absolutely nothing supporting her feather bullets being even remotely close to that powerful.

Literally first few sentances of abilities. A servant with mag res doesnt have to guard against simple magecraft like that. Forcing a servant w/ mag res to guard as a modern magus is a big deal

And where does this forced defense occur? Because if it's from the OVA that's just wrong, he isn't forced to defend himself, he swats the feathers aside without them doing anything. So where is it stated in this novel you mention that they were a threat to him? Because the OVA shows and the Script from Materials very much confirms the feathers as a complete nonissue.

This wiki is not a source, it is a collection of information from sources gathered by people, and the people who write articles can very much misread, misinterperate, misremember, or otherwise be wrong. So what is the source on this feat?

Cu Proto's only comment on the feathers in the OVA is "That black magic's pretty old style. It's kinda a waste, though."

No fear, no worry, no need to protect himself, he swings his spear that isn't even the Bolg to clear the first salvo which also launches Ayaka into the wall behind her, she fires again, a second swipe again scatters them harmlessly, she runs to the house's workshop and grows plants to block the door, he smashes through with minimal issue.

Any update on the supposed source?
