Violet Evergarden is a remarkable anime series about child soldiers recovering from trauma, about finding yourself through empathy for others, and there's a splash or two of action in there too.
The film opens in Japan next week, delayed for a second time due to the lockdown.
Kyoto Animation had to delay Free! Dive to the Future, but the film will make it out as an early 2021 release.
Kyoto Animation has commented on the arrest, except it's a bit of a no-comment other than to push for the full weight of the law.
Organisers of AnimagiC have told the press that the movie will go ahead, though, and at the express request of the Studio.
The suspect, a 41-year-old male, walked into Kyoto Animation's main studio, splashed petrol around, shouted "Drop dead" and then lit the fires.
