#I apologise for the extremely late post. University Work is kicking my arse.[/spoiler]
>"Maybe you can help her find a couple of books. She should still have some spending money."
>"I doubt she needs my help, despite her age she seems pretty knowledgeable on books. But I will try to find something that she'll want to keep."
>With that, Kosuzu leaves towards where Worm is probably making a ruckus of the literary variety.
>Skim the books for any swords or shrines
>The books, being a recounting and collection of a literal lifetime, take a bit of time to go over. Even just skimming for specific topics takes a while.
>You do find some information on various historical swords, most of which you somehow already know of (strange), and unexpected inclusions such as the Hisou no Tsurugi. But unfortunately nothing on cursed swords. And none that specifically use impurity that a human could use.
>Shrines bring a slightly more interesting return.
>According to the Seventh Volume, there was a Shrine Maiden who visited the Human Village occasionally. She was from an area outside of Gensokyo, so you can only guess that the visits to and from the Human Village were like pilgrimages to her. The Eighth Volume contains a bit more information about her descendants personally. Apparently after a personal meeting, Hieda no Aya finally got a name out of one of them:
Chen Satsujinki.>That's a... disconcerting name, almost makes you think it's fake.
>It seems that despite the extremely concerning family name, the Satsujinkis were generally respectable at most times but considered Youkai extermination an utmost importance to the point where most Maidens had weapon training of some kind. Sounds like the kind of Shrine Maidens who would use a sword on a Youkai.
>You attempt to look further into the books but don't find much other than notes on Gensokyo's politics, hints on how to avoid Youkai, and musical sheet music of all things.
>But what about the sword...
>Just as you ruminate on the weapon, Kosuzu returns with Worm in tow. Kosuzu looks like she had the life sucked out of her while Worm is carrying half her body size in books with an excited expression.
>"Mother, I may have figured out the secrets to the sword!" Worm yells.
>"Yeah, and all it took was barging into where the Youma books are kept and forcing me to read them to her." Kosuzu rubs her eyes to ease the feeling in them "She's somehow more excited about these books than I am. Almost gave me a heart attack when she went there."
>"So to summarise multiple books worth of enchanting, crafting and alchemy techniques short: It's possible to infuse qualities to an object by enacting a ritual involving surrounding the object in an environment rich in that quality for long periods of time. So you can, say, create an Impurity-infused sword by surrounding the sword in Impurity while enacting the ritual."
>"This is a centuries old technique and quite outdated in my opinion, however." Worm continues as if in a lecture.
>"Look at Sis here, acting like an expert in the fields of magic." Apple snidely remarks.
>"Hey, don't you remember that we're-" Apple remembers her cover. "The Daughters of The Omnyoji! Of course I'd be interested in some sorcery!" Interesting use of your new title there.
>So you've got a name and a weapon (or at least a process of how the weapon was made). Now you just need a method of tracking down The Satsujinki.
