Aside from there already being a "top 5 anime" thread
here and your doublepost, how can death note be your #1 when it's not even half through yet?
Plus there's gotta be something wrong with anyone liking Light as a person (yes it's Light, not that reverse katakana thing "raito", just as it's "death note" and not "desu noto" ).
Ah yes, and it's alchemy, not alchemistry.
