Kyriva

Lord Kiliva, also known as the Marquis Kyriva in the light novels, is the head of the clan that rules over the city of Tsukuba and its surrounding areas.

Personality
Kiliva is a very arrogant man and has a lot of pride. He believes that it is the Adventurers' obligation to fight off all monsters and does not react very well when the Adventurers do not immediately accede to his demands.

Return of the Goblin King Arc
When news of the goblin hordes attacking the nearby territories reaches the League of Freedom Cities Eastal, Kiliva and the other nobles have a secret conferenece to discuss the best way to deal with the threat. With the disappearance of the Izumo Knights, the Elder Tale Nobility had no choice but to sacrifice one city in order to trap the goblins and destroy them with their combined forces. However, this meant that the most likely city to be attacked, Tsukuba, would be sacrificed. Despite it being well-defended, it would lose more than a few fields and villages. At worst, the cost would be most of its population.

Kiliva goes on a tirade and begins demanding that the Adventurers deploy their forces to turn back the goblins. However, since the Round Table Alliance and Akihabara were not recognized as part of the League, and therefore had no obligation to lend any aid without a valid reason. This angered Kiliva even further and he was only silenced when Michitaka smashed his fist on the marble table, nearly collapsing it.
