Can someone teach me how to make a manga book/story?

Well, I can't exactly mostrar tu how to make a manga, so typing it up is the best I can do. You've got the basics--pencil and paper. I'd recommend using a 0.5 mm lead pencil and getting manga pens for inking out your work. You'll obviously need an eraser, so, yeah. Consider buying white-out for special effects, like highlights on dark hair, etc...

If tu need más advice, just tell me. :D

PEACE!
