Hill of Swords was rather fast paced, completing its run in a meager 23 or so chapters. It combined wonderful characterization, amazing dialogue, and events didn't seem forced or out of place. It's also possibly the most famous example of YMMV fic.
As with Ho S
, the fic is extremely YMMV. It isn't that focused on action, more on the slice of life. Coupled with slow updates, snail's pacing, and its extreme length, it's not for those who were accustomed to Ho S
's fast pacing.
It counts more as a Sekirei fic than anything else; it can't count as a Nasuverse fic since the only aspects present are the Clock Tower (which isn't taking its role as an antagonist seriously), and Shirou and his experiences. The characterization doesn't seem to be that well either in regards to Shirou. Sure, Rin and Saber show up, but for a meager two chapters before they're gone, possibly permanently.
However, it's amusing to read in some places and has long chapters and good grammar to enjoy.
