Episode 1108: The Secret Hidden By the Cards
Scenario: Within a certain bookstore, the Detective Boys were playing trading cards - Mitsuhiko was having a confrontation with Genta. While they play, Conan, Haibara, Ayumi, and Professor Agasa were watching nearby. On the other side of the table, stood two mystical people... also watching their games in silence.
Mitsuhiko dispatched a rare card called "Shake My Hand" and defeated Genta effortlessly. Agasa then explained that the bookstore used to only sell books exclusively, but now, since those Yaiba trading cards have increased in popularity, some parts of the bookstore are used for playing these trading cards. In addition, they discussed the fact that "some trading cards may become exceedingly expensive", and all of a sudden, the two mystical people who were initially observing on the side interjected with the protagonist group. Apparently, these two people were rather famous in the trading card circle: one of them was named Naoto Masaki; and the other one was named Tsukasa Nitta. Notably, Tsukasa, a lot of people showed esteem to him since he is able to win the trading card games with those cheap cards, whereas his opponents use expensive ones (even though he claimed that it was by virtue of not having money to purhase the expensive ones). As their discussion progressed, another trading card expert appeared - Daigo Zaizen. He is literally the "antonym" of Tsukasa, since he won several games by using ridiculously expensive cards. They seemed to have some arguments, but still decided to have a match with them. Just as they were pleased to begin the game, Daigo went to the toilet. He urged his entourage, Osamu Kuno, to keep an eye on his luxury cards and not let other people touch them.
Seeing Daigo's temporary leave, everyone looked rather inscened due to his inappropriate attitude. Tsukasa proposed that everyone ought to stay away from the table, as it would be annoying if Daigo accused anybody after his return. As such, he told the Detective Boys to go away, and he left the table as well, in the opposite direction.
Surprisingly, while most of the people had their backs facing towards the trading card table, one of the bookshelves (the one right behind Naoto) fell somehow. Immediately afterwards, the fire alarm was activated, and everyone who was inside the bookstore began to panic, raoring and dashing out of the premises. Nevertheless, the bookstore owner declared to everyone that it was a hoax after all - no fire.
However, when they returned to that trading card table, they saw Naoto being crushed under the massive and heavy bookshelf that accidentally fell during the commotion. Professor Agasa examined the body and found that he was dead.
Detective Takagi and Chiba arrived immediately to analyse the crime scene. Conan then saw that Daigo's entourage, Osamu, was looking for something next to the fallen bookshelf. Conan went to inquire of him about it, but he glossed it over and said it was nothing. Conan then scrutinised the bookshelf more closely and saw a bent nail attached to the top of that bookshelf.
On the other hand, Daigo was acting weird. He kept insisting and misleading the police to make them think that the incident was an accident and excluded the possibility of homicide. This made Conan point it out and ask him the intention behind it. Daigo then confessed - he was being blackmailed by the victim regarding how he cheated in one of his trading card games by peeking at his opponent's card beforehand; this was filmed by Naoto and was constantly brought up. What's more, Naoto did the exact same thing to Daigo's entourage, Osamu, as well. Therefore, Daigo possessed a valid motive for murdering Naoto; however, he kept denying committing the crime. Afterwards, Conan almost got slipped while stepping on a Yaiba trading card; Tsukasa helped him by raising him up in the air. At that instant, what Conan saw was the key to solving this case.
