yesssss spymaster Izuna!! a real shinobi, operating in the shadows! excellent!!

I have to admit, lately I've been wanting fics that touch on Izuna's speed. like, yes, yes, Tobirama is the fastest shinobi of his age/generation/time/whatever... but Izuna kept up with him for over a decade, so Izuna must have been a very close second. like. pls. pls guys, he was smart and he was fast and he wasn't useless ;-;
