The next light novel with an absurdly long title to get an anime adaptation is Mondai-Ji-tachi ga Isekai Kara Kuru Sō Desu yo? (Don't Problem Children Come From an Alternate World?).
The story follows Izayoi Sakamaki, a boy bored with the entire world. One day, an envelope arrives for him. The moment Izayoi opens the envelope, he is transported to an alternate world. There, he discovers that two other "problem children" were transported by envelopes as well a taciturn girl named Yō Kasukabe with a cat, and a beautiful yet haughty girl named Asuka Kudō. A girl named Kuro Usagi (Black Rabbit) summoned the three to the community "No Name" to overthrow the devil.
