- Ass Pull: The Reveal that Hiro was the culprit, a Villain Protagonist and was working with Hikari to get revenge for Atsuya. Not only does it get almost no Foreshadowing, but it directly contradicts almost all of Hiro's thoughts and actions.
- Ensemble Darkhorse: Kazu is easily the most well liked character in the series.
- Ho Yay: Plenty between Hiro and Kazu, before Kazu died.
- What an Idiot: Hiro is rapidly shaping up to be this, as per Tonogai tradition. Subverted in the end; he was Evil All Along.
