Intro
Evening. At home, Reiji is preparing dinner. The aroma of cooking wafts from the kitchen, and a meal for two is set on the table.
On the television, news of a recent villain incident in the city is playing. The screen shows a villain hidden by a black hood and mask, with only red eyes peeking out—"Umbra."
Reiji continues cooking while glancing at the TV. Soon, he senses someone at the front door.
