Gleam Garden no Shoujo -witch in gleamgarden-

There are girls in the world known as ‘witches’ who have the ability to bring disaster to their surroundings by merely wishing for something strong enough. This ability known as ‘gleam’ is said to be caused by a mental abnormality. Their numbers had increased rapidly over the past few years and society has gradually become more chaotic as a result. The ‘gleam garden’ is a place where witches are interned and where they are taught how to control their abilities so that they do not harm others. Touji is a ‘protection controller’, supporting four girls who had been cast off by society for being witches. He wants to lead them to a new life, and also to find out about the truth of his own past.
