i dont mean to brag about my obsessivness, but than again this is the exact reason why my friends call me otaku extrordinare... this is ALL back to back, ( i am not really sure if this really counts, as it took me servral days to watch all of it, but any way...) blood plus, chobits, FLCL, loveless, inuyasha, fruits basket, death note, the inuyasha movies, sailor moon, chibi vampire, full metal alchemist, code geass, kiki's delivery service, howls moving castle, spirited away, naruto (not after shippuden though) flame of recca, blood: the last vampire, and utawerumono. full series, all of them, all in one sitting, no breaks in between, and that is litterally half of the list, ill have to get the other half later. now i was eating and drinking while doing this, but i DO NOT reccomend it, because i had sleep depravation from this, and i fainted many times after pulling of practcally a week or so with out sleep... i watched maybe 25 full series, and 10 movies... all in one sitting... and yet after i got the badly needed sleep for about 2 months, i went on a game finishing spree, i am deffinatly an otaku extrordinare...
