Zettai Naru Kodoku

Minoru Utsugi, a teenager who lives a peaceful (if boring) life with his sister-in-law, finds his life changed when extraterrestrial contact grants his dearest wish, leaving him with the power of The Solitude. But the ability to realize absolute isolation only plunges Minoru into a battle he never wanted to fight. As his old life comes to an end, he steps into a new role… as the Isolator!
