Review of Absolute Duo

This anime feels very unresolved. Too bad the anime didn't do so well. I would have liked another season to at least patch up all the plot holes. The sister killer on Tor. The father killer Julie. The confronting of the sick people in that room that make children fight to the death with grown brainwashed men in tech suits (most messed up part). The weird unexplained psycho killer teacher. I give it a 6/10 for making me feel unsatisfied on many fronts. Also, there was no duo to romance advancement between the two main characters and no kiss. Very disappointing.
