I don't know. I'll have to read up on what happened. I just hope nothing from K-ON was destroyed in the flames if the company archives got set on fire.
Well, it was reported that the fire was caused by an arsonist, someone delibreatly set Kyoto Animation Studio 1 on fire and killed several people. But, I have some ideas for a possible sequel to K-ON, even though it might not be done by Kyoto Animation. I got this info from Wikipedia:
"After their third year, Yui, Mio, Ritsu and Tsumugi graduate and enroll into a university. There they join its light music club alongside three other students: Akira Wada, Ayame Yoshida, and Sachi Hayashi. Meanwhile, Azusa continues to run the high school light music club alongside Yui's sister Ui, their classmate Jun Suzuki, and new members Sumire Saitō and Nao Okuda.
The spin-off manga K-On! Shuffle focuses on a new set of characters at a different school. After being inspired by the Sakuragaoka High School light music club, Yukari Sakuma and friend Kaede Shimizu seek to form their own club. Along with classmate Maho Sawabe, they discover the Light Music Appreciation Society, a club run by Riko Satou."
