Kyoto Animation is without a doubt the best 2D animation studio in the world. Not only were they raising the bar in terms of quality of their work, but they were also setting an example for the rest of the industry with better working conditions for their employees.
Here's an in-depth article about them: https://blog.sakugabooru.com/2018/08/25/the-evolution-of-kyo...
Hopefully they can recover from this tragedy to keep creating new masterpieces.

Hopefully that will change after this. Safety regulations are written in blood, as the saying goes.
An exhaust would've helped.
Also please donate if you can to help the families of those that lost loved ones and those injured that will likely face a lifetime of disability.
EDIT: "one of the best" does not preclude Kyoto Animation from being "the best", but it makes it clear that you're not insulting all the other studios.
