A CITY OF HIDDEN DEPTHS!
In the year since the Battle of the Sanctuary, Subaru Natsuki has been
busy honing his skills alongside Emilia and the other members of their
merry band. Still, these peaceful days cannot carry on forever--and it
is none other than Anastasia, Emilia's rival in the royal selection, who
brings their respite to an end with an unexpected hand-delivered letter
bearing an invitation to the famous Water Gate City of Pristella.
Despite their suspicions about the sudden request, they accept and set
off for the trade hub that lies at the kingdom's border. There, among
the inviting canals and dazzling streets, await old friends, new faces,
and a hidden menace lurking in the shadows!
