The Crimson Love Letter is a simple and uncomplicated mystery movie that provides a good mystery without the intricacy of a complicated murder mystery or a locked room murder. Only after all the evidence has been collected is the culprit identified. In addition, the movie includes competitive Karuta, a sport in which participants engage in one-on-one matches to grab cards from their opponent's region. Whoever removes every card from their hand first wins. Although it's not required, having a thorough understanding of Karuta increases the excitement. The addition of Heji and Kazuha gives a distinctive twist to the mystery format, and the movie skillfully ties the Karuta battles into the main plot and character motives.
