Uhm, if your searching it for dub (English) I would recommend watching the 26 episodes -or whatever episode you're on- on justdubs.net but they seem to have problems with the videos, last time I checked.
So, I went on YouTube to watch the rest: link
Hope you like the ending as much as I did :)
-and hope this helped ^______^
Well i whatched it all on Netflix and i know foer a fact that those are all the episodes (26 to be exact) now if your looking for season 2 that would be Chapter of the Fledgling(which is written in the intro-if u watch it). Technically I dont think they are considered seasons considering that 1.)on Netflix it would show each episode total and each episode of each season (they are all labeled S:1 E:whatever) in the top left corner of the priview box. and 2.)Chapter of the Egg and Chapter of the Fledging each have 13 episodes-and yes i know there are animes with 12 and 13 episodes-and that would not be enough episodes for a multi-season anime. So i would like to consider Chapter of the Egg and of the Fledgling PARTS of the series so there are 2 parts in 1 season. Also there is only ONE season. Sorry if that dissapoints you. BUT, there are two manga versions though 1 of them is not by the origional writer though I plan on buying it(its on lulu.com if you want it. Its called Princess Tutu: Lohengrin by John Meadows) and i have starded reading the other on online. I dont think it matters what website you use and its just called Princess Tutu so i just searched princess tutu manga. I also read fanfiction when im bored(Fanfiction.net)if that helps at all. I guess thats all I hope I helped. Sayonara! ;)
