Dragons Descend on the Middle Ages: Summoning Heroic Spirits Through Gacha

Tyler arrives in the Middle Ages with an unfinished card-drawing game and becomes a newly hatched blue dragon.

From then on, the arrival of him and the magical tide sends the whole world hurtling toward a sword-and-sorcery age:

[Alfred the Great] founds the Knights Templar, unites the Seven Kingdoms, builds an immense northern wall, and holds off a horde of berserk Viking warriors at the borders.

[Cnut, Lord of the North Sea] sails west with a thousand ships, smashes London Bridge, and takes the throne of England.

[Richard the Lionheart] sets off on a crusade alone, his sword aimed at Jerusalem.

[Saladin, Sword of Allah] raises a sky full of yellow sand and holds fast in a besieged city.

Then one day, after successfully raising Valhalla into the heavens, Tyler discovers to his astonishment that these once-renowned enemies and friends have all become heroic spirits he can summon.

But before any of that, when Tyler has only just arrived and meets his very own “dragon slayer,” [Ragnar, the Norse God of War], he cheerfully makes a decision:

To pay for card draws, he’ll plunder all of Europe first.
