_Valis X: Valna – Haha to Musume no Kunou_ is the third chapter of the
episodic Valis X .
The common story of the five episodes of _Valis X_ is based on the events
depicted in various installments of the Valis series, describing the
adventures of a Japanese teenage girl Yuko Asou and her friends in a parallel
world named Vecanti, where she fights its evil tyrants with the legendary
sword of Valis. However, the episodes do not follow the plots of the
individual games; rather, they tell the over-arching story of the entire
series their own way, liberally mixing locations, characters, events, etc.,
and adding new sub-plots.
The first four chapters describe the same events from the point of view of
four different characters; the final episode concludes the story.
In the third chapter, the protagonist is Valna, Yuko’s twin sister who grew up
in the Vecanti dimension. She is an apprentice in magical arts, and is helping
Yuko to become the Guardian of Vecanti. The main story is the same as in the
two previous episodes; however, since this time we see the events through the
eyes of a local person, there are many new scenes and more background
information about the world of Vecanti.
All the episodes have the same graphical style and identical gameplay system.
Unlike the original Valis series, the episodes of _Valis X_ are “visual
novels”, composed of text and still images; interactivity is confined to
occasionally making a decision, which will slightly alter the following events
(usually of sexual nature), without influencing the general story.
All the episodes of _Valis X_ have large amounts of explicit sex scenes,
mostly revolving around lesbian sex and depictions of the heroines being raped
by tentacle monsters.
