Mondaiji-tachi ga Isekai kara Kuru Sou desu yo?

Sakamaki Izayoi, a boy bored with the entire world, one day receives a letter, with the following wording:

"This letter is for those of you with many troubles and extraordinary powers.If you wish to see how far that power of yours will take you, cast aside your family, your friends, your possessions, and come to our Little Garden."

The moment Izayoi opens the envelope, he is transported to an alternate world.There, he discovers that two other problem children were transported by letters as well — a taciturn girl named Kasukabe You with a cat, and a beautiful yet haughty girl named Kudou Asuka. A girl named Kuro Usagi (Black Rabbit) summoned the three to her presently unnamed (No Name) community, giving them a chance to participate in the Gift Games... well, and to use their gifts to help her weak community regain reputation, name and banner from the Demon Lord, who took those away in a Gift Game.
