Case

Situation

In a Japanese house in Arashiyama, Kyoto's outskirts, the reigning Satsuki Cup champion is murdered. Several karuta cards were spread around the victim.

Robbery(?)-Murder
	Location: Yajima Residence Victim: Toshiya Yajima Cause of death: Blunt trauma to the head Suspects: Koji Sekine, Kensuke Achiwa, Togo Kaieda, and Shikao Nagoro While Yajima is watching the match of Momiji Ooka, a mysterious man went to his room and killed him with a katana.

A bombing case at Nichiuri TV in autumn. The Satsuki Cup, which crowns the winner of Japan's Hyakunin Isshu, is currently being filmed inside the facility. The incident results in a big commotion and, while the building is burning to ashes, the only people left inside are Heiji and Kazuha. They get rescued just in time by Conan, who rushes to the scene. Both the identity and purposes of the bomber are unknown.

Bombing
	Location: Nichiuri TV Station, Osaka Victim: Heiji Hattori, Kazuha Toyama, and Mikiko Hiramoto Age: 17 years old (Mikiko Hiramoto) Injury: Explosion Suspects: Koji Sekine, Kensuke Achiwa, Togo Kaieda, and Shikao Nagoro Bombs planted in the building exploded, making it engulfed in flames. A bombing threat was sent, of which content is about karuta.

While confusion takes over due to the explosion, Conan meets a mysterious beautiful girl who claims she is "Heiji's fiancée". Her name is Momiji Ooka and she is the high school champion of the karuta game from Kyoto Senshin High School. As fate would have it, Kazuha is going to face Momiji in the Hyakunin Isshu, so she begins to train with the help of Heiji's mother, Shizuka, who is a skilled karuta player.

Koji Sekine is somehow related to Yajima's murder. Even though the crime scene looks like a robbery, none of Yajima's karuta-related things were touched. Also, the fatal wound was on the front of the head instead of the back or the side, suggesting that the murderer and the victim knew each other. And, Sekine knew that Yajima was beaten down instead of stabbed or slashed, even though the weapon is a katana and Sekine had no opportunity to look at the corpse.

Later, Ran finds out that Heiji once made a yubikiri/pinkie promise to 'take Momiji as his bride'.

Conan and Heiji, along with the Osaka and Kyoto police departments, begin their investigation on the Satsuki Cup and the related murder case. As the inquiry goes on, they come across a secret connected with the Hyakunin Isshu. They found that the cards that were left at the crime scene and sent by email to victims were all Shikao Nagoro's favorite cards, all of which had 'Momiji' in their poems.

Bombing

Resolution

  Show spoilers »

As Sekine wakes up, it is learned that he heard Yajima had been searching for Nagoro, and decided to surveil Yajima, only to find the latter's corpse.

Kensuke Achiwa is the mastermind of these crimes, while Togo Kaieda is the one carrying out the plan. Unbeknownst to the latter, Kensuke planned to kill him as well, in order to make it look like Nagoro accidentally killed himself. Nagoro, who had been missing for five years, had actually been killed by Kensuke's wife Satsuki Achiwa, who was shocked and afraid after losing to Nagoro one day before the scheduled match. Kensuke witnessed the murder of Nagoro, and decided to hide it so that no one knows. The fact that Kensuke didn't wash his car before the match suggests this, as everyone knows that Kensuke always do this every time Satsuki had a match. Yajima also noticed this and want to have evidence - the karuta cards that have fingerprints from a hand stained with Nagoro's blood; that's why he was murdered. Kensuke planned to kill himself along with Momiji and her opponent in the finals, who happens to be Kazuha, at Satsuki Hall, where Nagoro's body is kept hidden.

Bombing
	Location: Satsuki Hall, Kyoto Victim: Kazuha Toyama, Momiji Ooka, and Kensuke Achiwa Culprit: Kensuke Achiwa Kensuke prepares to suicide bombing with Kazuha and Momiji.

Murder (Past)
	Victim: Shikao Nagoro Time: 5 years ago Cause of death: Blunt trauma to the head Culprit: Satsuki Achiwa Nagoro challenged Satsuki, but she unfortunately lost.

Before he detonates the bombs, however, Momiji reveals that the reason why Nagoro challenged Satsuki one day before the scheduled match is not to humiliate her, but rather to show her, Nagoro's first love, the full extent of his skills before he lost his sight. The hall then starts to crumble because of the previous explosions. Conan, Kensuke, and Momiji evacuate using the elevator, while Heiji uses his bike to take Kazuha to a nearby ledge.

After the case is solved, it is finally learned that the story between Momiji and Heiji is actually a misunderstanding. Back then, when Heiji defeated Momiji, he said "next time, I'll be even stronger (tsuyome)", but Momiji misheard it as "yome" (bride). Momiji calls her butler immediately and leaves, but not before finally calling Kazuha by her name and declaring that once she has a favorite card, she won't let anyone take it from her.
