[Crossover] Serna's Choice

Somewhere unknown, there is a strange clinic. By day, its sign reads "Go to the Heaven." At night, it becomes a bar, with a sign that reads "Go to the Hell." The clinic's doctor is Miss Yin Serena, as lovely as an angel. The bar's proprietress is Madam Yin Serena, as terrifying as a demon... The former is pure and adorable, while the latter is alluring and seductive... The clinic's visitors are all devout believers... Their longing for beautiful things is answered. The bar's visitors are all embodiments of evil... Their devotion to darkness and sin is answered, too.

Both the clinic and the bar have a strange potted plant... A vine grows upward inside it, covered in black and white fruit.

White represents Heaven... Black represents Hell... And Yin Serena stands between them. The choice she makes will decide where she ends up.
