I wasn't aware of the attack until recently. Like many people here, I have fond memories of Kyoto Animation, and was looking forward to their next projects, particularly the second season of Miss Kobayashi's Dragon Maid. Dragon Maid is among one of my favorites from the studio, including Kanon, Clannad, Haruhi, K-On, and there are still many of their works I plan to watch.
And now to hear that everything they were working hard on, and the lives of so many people in KyoAni have gone up in flames, all because of some asshat with an unjustified grudge, is just sad and heart breaking beyond belief. I don't know, nor do I want to know, what went through this man's mind when he did this, but I hope he gets everything he deserves for his crimes and then some. My heart does to all the people hurting from this attack, and I prey to all the souls and hope they find some peace.
