Aesthetica of a Rogue Hero (Japanese: はぐれ勇者の鬼畜美学（エステティカ）, Hepburn: Hagure Yūsha no Esutetika) is a Japanese light novel series written by Tetsuto Uesu and illustrated by Tamago no Kimi. A 12-episode anime adaptation by Arms aired between July and September 2012. It has been licensed in North America by Funimation. The story follows a world where several young men and women regularly find themselves spirited away to a world of sword and magic called Alayzard (アレイザード, Areizādo). Those who survive and return are typically gifted with magic abilities. An international training organization named Babel protects these young returnees and trains them in the use of their power. A wayward hero named Akatsuki has come back to his world, along with a beautiful girl called Myuu who is the daughter of the Last Dark Lord, whom he defeated in battle.
