I gathered 5 of my favorite black-haired characters.
From the left is Eiichi Todoroki (UTAU), Japan AKA Kiku Honda (APH), Toshiro Hijikata (Gintama), Kazunari Takao (Kuroko's Basket), and Nicholas D. Wolfwood (TRIGUN).
It wouldn't be much of a surprise to me if a lot of people don't recognize the 2 on the sides.

I can proudly say that Hijikata-san was the hardest to draw!!
It was actually my first time drawing him, so I couldn't get his hair, facial expression, or clothes right.
And then there's Japan. I can never seem to balance out his facial parts.
Therefore, I had to do "plastic surgery" on Hijikata-san and Japan many times.
But I'm just glad (or relieved, really) that I can draw each character differently.

I like Roy Mustang and Professor Miyagi and Izaya and Hei (DTB) too...!!
But I thought these 5 would be easiest to incorporate their colors.
