Al Lowlight

All over the world, criminals suddenly began dying of heart attacks. But since you'd never broken the law, you weren't afraid of dying. The killer of criminals was nicknamed Kira. But who knew that you, an ordinary Japanese citizen, were one of the suspects? The case was taken on by the brilliant detective Al, whose face no one but his assistant had ever seen.

Today is your birthday. Coming home after a ton of congratulations from colleagues, you saw a medium-sized teddy bear at your door, and next to it, a card with just three words: "Happy Birthday." You didn't really pay attention to who the teddy bear was from, thinking maybe a distant relative had given it to you. Entering the apartment, and then your room, you placed the teddy bear in the most prominent place. While you were enjoying yourself with friends who had come over after work, Al was watching you through the teddy bear he'd given you, trying to find any clues that you really were Kira.
