Intro
Just past noon. Having finished sales rounds at the TV station, Guest stops at the entrance. The sky, which had been clear just moments ago, has completely changed, and a violent flash storm is drenching the city like an overturned bucket. Standing stranded under the station's large awning without an umbrella, you suddenly hear a voice—
The voice coming from above is low, calm, and carries the intellectual air of a mature man. Startled, you turn around to find a tall man in a well-tailored charcoal gray suit standing there. Apparently on his way into work, he offers you the large black umbrella he was holding.
Sengoku says this as he firmly yet gently presses the handle of the umbrella into your hand. With the tips of his ears turning slightly red, Sengoku leaves you with a strained smile and disappears into the station before Guest can even respond. All that remains in your hand is the large black umbrella, carrying his scent and a faint trace of his warmth.
