===Locked Room Piggy Bank Theft Case===
The younger sister calls the Metropolitan Police Department to report that the money in her piggy bank has decreased. The Investigative Division sends Totomaru Isshiki to her house to investigate this case; he brings along Ron Kamonohashi who introduces himself to the younger sister as Kamoo Kanetamaru from the 110 Piggy Bank Company.
She lets them in and leads them to the living room where the piggy bank is kept. The younger sister confirms that she and her older sister were away two days ago; and when she returned yesterday, she noticed that the piggy bank was lighter than before. Ron inspects the piggy bank and notes that the potential thief did not take any of the jewelry displayed in the living room. The younger sister also tells him and Toto that she and her sister have been receiving odd phone calls lately. This made her feel unsafe and prompted her to make sure that all doors and windows were closed and locked before she left a few days ago. Then, the older sister comes home.
They sit down, and the older sister testifies that she returned home yesterday as well, though a bit earlier than her sister. She says that, to her, the piggy bank does not seem lighter than before. Still, the younger sister insists that she is not imagining things and that the piggy bank used to be "as heavy as an iron statue." Hearing this, Ron swipes his hair to the side and suggests breaking the bank. They break it, and the younger sister states that there are less coins than before. Ron tells Totomaru to send the coins to the forensics lab. They then leave the sisters' house.
Later, the sisters are called to the river where Totomaru tells everyone "his" deduction: The piggy bank theft and the river corpse cases are connected. The dead man is the older sister's stalker who waited for her when she returned home. He backed her into the living room, and she grabbed the piggy bank and hit him in the head with it. The man died, and the piggy bank broke. The older sister purchased a new one and put in some new coins and moved the body in a suitcase to the riverbank.
The younger sister cannot believe this, but to her shock, her sister confesses to the crime. Right afterward, Ron pressures the older sister to drown herself in the river. Totomaru holds back Ron and tells Amamiya to go and grab the older sister who is heading to the river. The younger sister watches her older sister escaping from Amamiya's grasp and walking into the river. Fortunately, Totomaru is quick to jump after the older sister and is able to save her.
