The Isolator
Plot. When Minoru Utsugi was eight years old, home invaders killed his parents and older sister while he hid in a cabinet. At 16, he still struggles with the trauma. Then mysterious alien orbs descend from the sky and take up residence inside some humans, granting them each a superpower that reflects their deepest desire. Minoru's power is the ability to protect himself inside an impenetrable shell. Some people gain a more active power, and not everyone uses their power for good. Reception. Yen Press' English edition of the first light novel volume received a positive review  from Anime News Network. It was praised for its "believable characters" and the thought that "switching between the hero and villain's point of view really works." However, it was said that Shimeji's illustrations can make Takaesu (the antagonist of the first volume) "more wolf-like than shark-like in some images."
