Tasogare no Kimi Wolfinne ~Mahiru no Kuni to Tsuki no Kuni~

"When darkness covers the world, a savior will awaken from deep sleep."

In a Place far than Here, at a Time far from Now...... Two kingdoms fight over who will control Sun Planet, that most cherished source.

If the Kingdom of Noon wins, they will cast light on the world.
If the Kingdom of Moon wins, they will cast darkness.

On the birthday of Noon Empress Fimosi, the Kingdom of Moon launches an attack that shrouds the world in shadow. Fimosi escapes to safety. She must defeat her rival and restore the light...

It can only be done by borrowing the power of Tasogare no Kimi, meaning "You of Twilight"......

"The legend rises now......"
