Mine is Berserk, it's really awesome and immersive. Also, it motivates me to work-out and live my life to the fullest. If you write your favorite manga, please add an explanation why it is your favorite.
My favorite manga is Naruto and Onepiece, I always wait every week to read manga ...
and I always feel sad when the manga is off ...
maybe by reading manga I can fill my vacation time at home ...
