Anime and Manga Differences

 * Conversaion between Reigen and Amakusa runs slightly different in anime.
 * Amakusa offering money to Reigen, and him talking about parents happens only in anime. In the manga Reigen decides to go with Amakusa, because there was no other way to get rid of him and he was worried that if what he says is true, then it can scare away customers.
 * In the manga, first yokai that appeared was killed by Serizawa, while Amakusa was charging his energy. Then, when more yokai appears, Amakusa breaks his sword in first use. In anime, Amakusa saves Reigen from attack from first yokai, then breaks his sword while trying to defeat him.
 * Price of Amakusa's holy sword is anime-only.
 * Serizawa fighting with his business cards is anime-only. In manga he uses regular exorcism.
 * In the manga Reigen suggests escaping, when Yokai King and four generals appear.
 * Note that Mob's costume didn't leave an impact due to bad lightning is omitted.
 * Teru and Awakening Lab students appear at festival only in anime.
 * Scene with Reigen updating his website is anime-only.
