Because it's kinda difficult to take the show as it is and insert an entirely new character while keeping the essense of the scenarios and results the same as Canon... Ne, Keroko?
But on the other hand, I've seen some already. Like the StrikerS Final Battle inserts. You also have links of them as far as I can remember. But that should be rather spoilerish for Fenris to watch now.
Oh, and BTW. Mewants that AU fic too! >:3
(No pressure, though.;3)
Nya? I think you have the wrong person. The one writing that fic is Kyral, and his projects can be found here. And if you want angsty and Vivio, then you should definetely read Alpha by Kagerou. You can find it in Satashi's first post on the index page.
Thank Kami-sama! It finally worked. Okay, basically I'm a new fan of Nanoha and I'm trying to get my hands on some interesting fanfics while waiting to watch the series since my computer and youtube don't like each other. If its not too mucht trouble could you please send me a link to your Darkness Overwhelming fanfic? Or if you know any good angsty fics about Vivio that would be good to. Sorry to bother you, hope to hear from you soon.
