Inou Battle wa Nichijoukei no Naka de

From MangaHelpers:

Half a year ago, the four members of a literature club, as well as the elementary school niece of their faculty adviser, were bestowed with supernatural powers. The boy in the club, Ando Jurai, became able to produce black flames. The girls acquired a variety of powerful abilities: Tomoyo could slow, speed, or stop time, Hatoko could control the five elements (earth, water, fire, wind, light), little Chifuyu could create things, and Sayumi could repair objects or heal living things. However, since they gained these powers, nothing has really changed in their everyday life. Why have they been given these powers in the first place? Will the heroic fantasy life they imagined these powers would bring ever actually arrive? [tethysdust]

-------------------------

The five members of the literature club awakened with extraordinary powers half a year ago. Although the members expected to be thrown into a world of super-powered battles at their school, their normal daily routine continued. No secret organizations bent on world destruction, no super-powered wars, no brave heroes or demon kings. However, the members still look forward to the possibilities of adventure, and continued to believe that with each day, they were getting ever closer to those days of fantasy. Their days of romantic comedy and battles with extraordinary powers begin!
