FIRE EMBLEM: SEISEN NO KEIFU

The story is set in the continent of Jugdral, home of the descendants of the Twelve Crusaders. Lord Sigurd is the hero for the first generation, fighting an invasion from Verdane and helping out in the lands beyond. Sigurd's son, Celice continues his father's legacy in the second generation, where he rallies an army to defeat the Grandbell Empire.

From Baka-Updates:
Based on the Super Famicom strategy game, Fire Emblem 4 features the son of Lord Byron of Chalphy, Lord Sigurd. Bandits from Verdane made an attack while Grandbell's armies were away, and now Sigurd rallies the remaining forces to drive the bandits out so he can save his friend, Adean... Little does he know what he leads himself into will lead into a tragic turn of events in the face of Grandb.
