## Biography

### Poisoned Latté Case

Hayami visits Pot Coffee with her friends Julie and Tamada. They order lattés for each of them, and Hayami picks them up from the counter. When she sees the coffee art on the lattés, she mistakes the platypuses for ducks, much to Ron Kamonohashi's annoyance. Hayami then carries the lattés to Tamada and Julie.

Not long afterward, Julie collapses to the ground and dies after drinking her latté. Hayami and Tamada are shocked, and the police and an ambulance are called. When they arrive, Hayami and Tamada watch them secure and inspect the crime scene. Forensics reveal that a cyanide capsule was slipped into Julie's latté which means that she was murdered. Only three people had the chance to slip the capsule into the mug: Ron who made the lattés, and Hayami and Tamada who were with Julie. Chicory Monki then announces that Totomaru Isshiki will solve the mystery "magnificently."

Totomaru questions the three suspects: Ron only says that although his lattés were "perfect," Hayami said that the platypuses were ducks. Hayami testifies that after she brought the coffees to their table, Julie insisted on taking a group picture. Then, Hayami's boss called her and Julie left the table to take pictures of the shop's interior; until they returned to the table, Tamada was alone with the coffees. Julie died right after taking a sip from her drink.

Ron notes that they could have all poisoned her, but Toto says that Ron did not know Julie and has, thus, no reason to kill her. He also could not have known which latté she would drink and has no motive for indiscriminate murder. Hearing this, Hayami and Tamada remember that Julie did not take the latté closest to her, but the one from the back of the tray.

Later, Toto gathers everyone and states that it was not an indiscriminate murder: Julie was targeted and murdered. The killer knew that Julie would choose the cup at the back of the tray. The answer could be seen in Julie's social media account. In all the pictures, Julie is standing in the center of everyone where she would stand out the most and where she would look the best. For someone like her, it was inevitable that she would pick the latté that looked the best without knowing it was poisoned. Hayami remarks that all three lattés look the same, but Totomaru tells her that they only looked the same until a certain moment: The killer used a nail to scratch the two lattés that had no poison. It could be done in a moment without anyone noticing, even in the short time needed to carry the lattés to the table.

The photo in Julie's account provided proof. In contrast to Chicory's picture in which the platypuses are all the same and which was taken when they were still at the counter, in Julie's picture, which was taken when the cups arrived on the table, two platypuses are scratched at the head. Thus, only Hayami could have done it.

Hayami breaks down and confesses. She poisoned Julie because she always wanted to be the center of attention and stole her boyfriend after he had been scouted by a talent agency. Her avowal triggers Kill on Sight, and Ron orders Hayami to smash her head on one of the teapot sculptures in the shop. Hayami goes to the kettle, holding it to smash her head, but Toto can stop her just on time by throwing a bag of coffee beans between her and the sculpture.

## Etymology

* "Hayami" means "speed, quick, fast" (速, *haya*) and "water" (水, *mi*).

## Trivia

* Some English subtitles mistakenly state that Hayami was scouted by a talent agency, not her boyfriend.
