It’s a beautiful night.
The moon is full and the dark sky is painted with bright stars.
Inside the banquet hall of a high-rise and luxurious six-star hotel, Nōburu Oriental, a beautiful young woman is gracefully walking down in the grand staircase.
She’s wearing a dazzling red dress encrusted with expensive diamonds and pearls whilst a flower wreath adorned her head.
The crowd stared at her in great admiration, appreciating her beauty and elegance.
However, just as she had reached halfway down the stairs, her heel accidentally slipped and she lost her balance.
The crowd gasped sharply in utter horror, but only one young man tried to save the falling woman.
Unfortunately, he was too late. Tachibana Mayumi had already fallen down the stairs and hit her head hard on the floor.
Blood trickled down the floor. Minamoto Giichi ran towards Tachibana Mayumi and lifted her limp body in his arms.
"What are you all staring at?! We need to get her to the hospital immediately!" His loud, commanding voice awakened the gaping crowd and they finally reacted.
Unbeknownst to them, though unconscious, Mayumi had seen inconceivable things that will change their lives forever.
