yes i notice too i like bleach soul society arc and arrancar arc was my favorite. I love Aizen , i know he is bad but sexy bad character!
About shounen my favorite was lodoss but after he is Naruto,Fairy Tail, Ranma1/2, inuyasha, flame of Recca, Gundam Seed, there is so many shounen that i love. By the way do you start to read fushigi yugi genbu?
Lodoss it's heroic fantasy manga, it's small serie but really good. for lot of people DBZ it's the best shonen i like naruto, but my favorite was lodoss because at moral at the end is very good.
You like Gundam seed too what your favorite couple and character. I watch gudam first serie before Gundam seed, with Heero and i like it but i prefer gudam seed, i don't really like gudam seed destiny.
From Gundam my fav couple is Alleluyah and Marie (from gundam 00) My Fav character...well i guesss its a draw between Heero (Gundam Wing Endless Waltz) and Setsuna (Gundam 00) Best History line goes for Gundam Seed/ Seed Destiny.
Gundam Series has alot of romance thats why i love it <3
