Unlike the previous Viper V games, Viper V-16 includes only two stories
instead of the usual three. The stories are called Rise and Imagine.

Rise tells the story of Akira, a young girl who works in the Anna Miller
restaurant chain in Japan. Beside being a waitress, she is also a skillful
martial artist. One day she and two other girls are kidnapped by mysterious
creatures, who turn out to be a subterranean race that needs human females for
reproduction. Will Akira manage to escape and rescue her friends, or will the
three girls remain forever in the hands of the cruel captors and their
horrifying leader Seed?

Imagine tells a quieter story without any supernatural elements. The
protagonist is a male high school student who is looking for a girlfriend
(aren’t they all?..). He meets three interesting girls, one of which dreams to
be a voice actress, the other is an aspiring musician, while the third is
unsure about her future. Who will be the lucky one to end up with our hero?

The two stories are more developed compared to the previous Viper-V short
stories. As always, there are animated scenes with sexual content in the game;
the interaction is once again confined to occasional choices. In Rise ,
wrong choices usually lead to bad endings; in Imagine , the hero ends up
with different girls depending on the player’s decisions.
