TriviaEdit

  • A recurring theme in the series sees Side Effects contributing to their possessor's misery:
    • Chika's Side Effects allowed her to escape capture at the hands of Trion Warriors for years, and are thus indirectly responsible for her feelings of guilt after her friend was abducted;
    • Following his father's death, Yūma's Side Effect allowed him to see through the empty platitudes and attempts at manipulation of the people who surrounded him, some of whom would have preferred his father to survive him.
    • Jin's ability to see the future comes with great responsibility, as he may be forced with the choice of letting someone be injured or even die to prevent a worse outcome. His Side Effect is also implied to be the reason he willingly gave up Fūjin, the Black Trigger his beloved mentor had transformed into.
    • Kikuchihara was mocked for the supposed inutility of his Side Effect, with it causing him to overhear himself being mocked.
    • Murakami lost friends due to his Side Effect allowing him to surpass them in their favorite activities in a short time, causing the group to disintegrate.
    • Kageura is not only privy to others' negative feelings towards him, but the prickling sensation provoked by his Side Effect is all the more unpleasant if the emotion directed at him is a negative one.
