The Scarlet School Trip (Crimson Love Arc) Shinichi solves the ciphers and is able to catch the culprit while he attempting to kill Mayama. It turns out Agata was trying to avenge Dekuri's suicide. Dekuri originally wrote the plot for the film in a comic during college and asked to be credited for the movie. Dekuri had killed himself because his name was mistakenly not included during the first screening, and Agata believed Nishiki, Ihaya, and Mayama had done it purposely. It was revealed that because of some restrictions, instead of listing his name separately, Dekuri's name was intended to be formed with the kanji or the rest of the film crew's name, and the spacing was fixed for the film's release. Shinichi returns to his classmates, and asks Ran for her response to his confession in London...
