Differences Between the Anime and Manga

 * Before the title card, an extra scene is added where Miwa says his side of the story.
 * After that, it shows the end of the previous episode and then the title card.
 * A Flashback that showed Reiji Kizaki was cut from the Anime and was replaced with Osamu Flashbacks.
