Case

Situation

Part 1

While on the way to a Yoko Okino concert Kogoro loses his ticket. Luck seems to be on his side when a young lady named Masayo Aoshima has an extra ticket, but the concert ends up being the last thing on their minds when they walk into her sister Mina's house and comes upon an apparent suicide.

Suicide?
	Location: Aoshima Residence Victim: Mina Aoshima Cause of death: Loss of blood Suspects: Masayo Aoshima

Conan has his own suspicions though, but can he find enough evidence to prove contrary when the victim is found in a sealed room.

Part 2

Just as it appears the perfect crime has been committed, Detective Takagi returns with news that could show Mina cared more for her sister than anyone realized. When a spot of Mina's blood is also found on the door, it is all the clues Conan needs to prove Masayo murdered her sister.

People

Mina Aoshima
	Victim (wrist slit) 24 years old Haido Department Store employee

Masayo Aoshima
	26 years old Beika Bank employee

Kenji
	Mina and Masayo's friend

Resolution

  Show spoilers »

The culprit is Masayo Aoshima. She killed her little sister and roommate Mina after, for several years, she copied and imitated her in everything; at first she found it cute and funny, but later she thought it was disturbing, and then she snapped when Mina told her she and Kenji, her ex boyfriend, were dating, and she said it in a tone that was the last straw.

At first, Masayo's plan was to lock Mina in a makeshift poisoned/locked room with a poured bathroom cleaner as the improvised 'weapon', expecting Mina to die of asphixiation. The cleaner was too soft, however; therefore Masayo knocked her victim out, filled the tub with water and slit Mina's wrist, placing her injured arm inside the water so she'd bleed out faster. Then she left Mina's lifeless body and got ready to leave to the Yoko concert, using Kogoro as her alibi...

The clue that let Conan identify Masayo as Mina's killer was the reddish Yoko headband that she was wearing. One of the letters forming Yoko's name was smeared in something red -- Mina's blood, which was not only on the water but on the door. At some point Masayo looked through the keyhole right after killing Mina, and that's when her headband got bloodstained.

After Masayo was cornered, had her cover blown and explained her reasons, Kenji said that Mina never intended to hurt Masayo's feelings; in fact, he was the one who asked her out, and Mina said it was her to not make Masayo feel needlessly bad. Conan-as-Kogoro adds that the cleaner was a soft one because Mina purchased it thinking of Masayo's safety since she was the one who usually cleaned the bathroom at home. Masayo emotionally collapses and is seen holding Mina's lifeless body in tears.
