Albireo no Namida ~Yokoshima Ryuu to Seiou no Ko~

In a world divided by good and evil, there lived two extremely beautiful princes. Though both originally hailed from the same kingdom, one day the elder twin, Prince Afnan, vanished without a trace. Prince Najaf of the Kingdom of Amjad, a realm that upholds righteousness and the inherent goodness of humanity, resolves to rescue his brother, who'd been abducted by the Kingdom of Nahara—a nation that places its highest value on conquest and expansion. Yet, his path is obstructed by the very instinct for conflict, the duality of good and evil, that has been ingrained within him. This is the story of those who confront and battle against the deep-seated prejudices that plague their world. [Translated from Novelgame]
