Good luck reading through the first three chapters, it was a gigantic turn off for me and i don't think the author avoided gary stu-ism at all, specially Toshiro. And Naruto is -even- dumber than before, to make said captain stand-out more by comparison methinks.
Clearly this fic is not for everyone, there's some small things there that might rub a lot of people the wrong way.
At least it seems to be well written, i didn't read it that far.
If you are a toshiro fan though, i say 'read it!', you might like.
