XSEED teases new reveal with terrible poetry

Localisation expert XSEED is teasing an imminent announcement. Can you guess the game from these scant clues?

The publisher released a couple of clues to an impending reveal via Twitter. The first is:

"Wearing a dress you / may seek a horse for revenge / to duel distant foes."

Followed by:

"If you crawl nightly / and blind watching eyes, you may / uncover a prize."

A final hint came in non-Haiku form:

"Tom suggests that: 'When in battle, always remember to dock and perry.'"

The mysterious game will be revealed tomorrow.

XSEED is best known for its sterling efforts bringing Japanese games to western audiences, especially on PSP, but has recently begun releasing games on Steam. It has a strong relationship with Acquire.

Any ideas? All I've got so far is female protagonist, stealth, and combat - which is pretty vague.
