Who is your favorite mangaka and why?

I'm interested in hearing from you guys since there seems to be a lot of debate in comments of different manga, pertaining to the mangaka.

So, I'll go first. Mine would have to be, after a lot of consideration, Harada-sensei.

I know; odd.

The reason I like her so much is not for the dark theme (in fact, I typically avoid dark like the plague), but I can't stay away from her work and she's one of my go-to mangaka when I don't know what to read. Will avoid some of her work? Yes (Nii-chan, comes to mind).

But I think the main reason why love her work so much is that she is best, as far as I've experienced, at expressing just raw, intense emotion. Example in point, the scene in Yatamomo where Momo has a break down and is just bawling his eyes out. It was the first time that I felt the pain of the protagonist rather than just watching it.

But all in all, this raw energy and emotion is the reason why I love Harada-sensei.
