  • Moral Event Horizon: Ryuuto's teacher crosses this when he tell his students to cover their eyes and stand in a corner, then lets the swarm of rats in and runs for it, leaving an entire classroom of elementary-schoolers to be eaten alive. Sure, they were Asshole Victims but still!
    • He was also going to trick Ryuuto into eating a rice ball spiked with poison, out of fear that he would suspect his involvement in the students' deaths and rat him out, even though it's clear Ryuuto is too kind-hearted and naive to do so. Only the timely intervention of Kizaki, who was perfectly aware of the teacher's intentions from the beginning, prevented Ryuuto from dying an early death.
    • Then the later actions of lying to Togakushi twice (first that he saw his children leave the city, then that they were dead) just to save his own ass, and then driving off to leave Togakuchi, Asagiri, and the children to die.
