Kilkapul

Kilkapul is a summoner who is one of the Four Demon Kings.

Appearance
He looks like an unassuming normal old dwarf.

Personality
He is a calm and polite person but is still a general of the Demon Lord (Gaeabrande), therefore cruel and evil. He is willing to sacrifice his family, village, and even himself to serve the Demon Lord (Gaeabrande), showing an unwavering loyalty. He is also observant and wise, as unlike the previous demons, he opted to watch Seiya (instead of attacking immediately) and realized Seiya had a power that went beyond logic or reason.

History
The party unknowingly met him at his item shop to buy torches at Izale village before they went into the Dragon's Den. When they return to the village, he is discovered to actually be a general of the Demon Lord (Gaeabrande) and has razed the village. He reveals that his summoned Adamantoise has destroyed the legendary armor they came for. He also shows the party the head of his wife and child, explaining that in order to stop the abnormally powerful Seiya he has to resort to abnormal means, which requires him to sacrifice his village, family, and himself to summon Crossed Thanatos, a nigh-invincible monster. Kilkapul then slits his own throat to finish the summon.

Powers and Abilities
As one of the four heavenly kings, he is quite powerful. Like Deathmagla, his main strength lies in summoning. However unlike Deathmagla he seemingly cannot summon entire armies (or he chooses no to), and instead seems to focus more on the summoning of single, powerful monsters. He is also adept at a ritual summoning.
