A good chunck of the characters from the first half on the manga. I tried to stick to the manga's colours as much as possible, and since I wanted to avoid drawing everyone in the same clothes I looked for instances where they'd be dressed up differently. They're really fun to sketch and I want to do another set with characters from outside the school, but man, Bill dressed up as Adler took me a while xD If I were to add anyone else to this set it'd probably be Els and maybe Collot, but I think it's complete enough as it is.

There was also another really cool character in the school, but I don't want to ruin the surprise for everyone.

Edit: I made a huge expansion of this piece. Make sure to check it out!
