Pursuit

Light explains to Ryuk that he intends to scrub every criminal from the world and preside over it as a divine authority. Such a reign requires longevity, so he declines the trade that would grant him the eyes capable of reading names, since surrendering half his lifespan would cut his rule short. Wanting firmer data on the notebook, he runs lethal experiments on imprisoned offenders, and the resulting cluster of bizarre fatalities leaves his father and the detective heading the case deeply confused.

By breaking into the confidential files, Light discovers the investigation already reads these deaths as controlled trials, a conclusion being withheld from the press. He counters with a scheme to expose his shadow, booking an amusement-park outing with a classmate named Yuri. The agent climbs aboard the same bus and takes the seat directly behind the apparent couple.

During the ride a wanted dealer and killer, Kiichiro Osoreda, storms the bus and aims a pistol at the driver. Light slips Yuri a note claiming he will disarm the gunman with a technique from his father. The man behind him objects, and when Light brands him an accomplice, he is forced to flash federal credentials to clear himself. Light then lets a slip of paper fall and stretches to retrieve it, prompting Osoreda to snatch a note holding the date plans.

Because that sheet was torn from the notebook, contact lets the gunman suddenly perceive Ryuk. The death god strolls toward him, and Osoreda empties his weapon in a useless panic before halting the bus and bolting outside, where a passing white car strikes him dead. As officers gather statements and the agent slips away, Light returns to his date already mapping out how the federal man will die. The episode also clarifies that a written time of death can be adjusted if recorded within forty seconds of the cause.

A timing slip appears when Light schedules six convicts to die at six in the evening, which places the writing an hour earlier and clashes with the cram-school and daylight details established in the opening episode. Another deviation involves the gunfire aimed at Ryuk: here the bullets pass straight through the death god, whereas the manga shows them landing on him without doing any harm.
