Season 2 of Minna Atsumare! Falcom Gakuen.

Characters from various games released by Falcom (e.g. Dragon Slayer, The Legend of Heroes, and Ys series) come together in a crazy academy life in celebration of the game maker's 30th anniversary.

Ten years ago, a massive invasion by the Erebonian Empire almost shattered the Kingdom of Liberl, piercing to the heart of Capital City before being driven back by a determined counteroffensive led by Cassius Bright. Now, as the invaders pace behind the northern borders, coveting the small kingdom's magic and high technology, Liberl slowly rebuilds with the aid of the Bracer's Guild, whose mystical use of "Craft" is even more intrinsic to the nation's defense than its own army. For young Estelle Bright, daughter of Cassius, this is all just ancient history that she and her adopted brother Joshua learned as kids. But history has a way of repeating itself, and as they prepare to join the Bracers Guild themselves, sinister forces are preparing to thrust them into the familiar family situation of being in the worst possible place when mayhem breaks out. Because when their father's airship goes suddenly missing, of course it only makes sense for two green, but extraordinarily capable, young teenagers to strike out on a rescue mission of their own! <br><br>

Faaren is a peaceful and happy realm, ruled by a wise King... until the Demon Lord Ackdam overruns the kingdom with his black legions and terrifying dragon, killing the King and capturing the Queen. But the King's young son, Sirius, is swept away to safety and grows to be a powerful young warrior, tutored in the ways of swordsmanship and chivalry by his father's loyal minion, Rias.

Now that Adol Christen has saved the land of Esteria from the evil priest Dark Fact, Adol and the two priestesses travel to the floating land of Ys, where evil has an even greater influence on the people and no one has hope. The future of Ys falls to Adol, heir to the powers of the priests and the only one who can show the people of Ys the truth about their world. But, as Adol's power grows, he may be the one who will save Ys -- or destroy it. <br>

Adol Christin, a young man from the mainland, sails to the besieged land of Esteria in search of adventure. Esteria is being overrun by beasts under the control of the evil priest Dark Fact, and the people of the land are running out of time. However, there is a prophecy that tells of a hero from another land who will come to save Esteria -- and his name would be Adol Christin. <br>
