Kralgra (クラルグラ) was a mithril class adventurer group of the Re-Estize Kingdom.
Igvarge and his team had trained hard to fulfill their dreams as adventurers. They slowly climbed the ranks after countless close brushes with death, eventually becoming recognized as mithril ranked.

Kralgra, Sky Wolf, Rainbow, and Darkness were summoned as mithril class adventurer groups of E-Rantel to discuss the appearance of the powerful vampire, Honyopenyoko. Momon insisted that the Darkness will fight against Honyopenyoko alone, arguing that involving others in the fight would only increase the number of victims. Sky Wolf and Rainbow accepted his opinion and did not participate, but Kralgra ignored his advice and chose to follow.
Reaching the site of the vampire, Momon's allies revealed themselves and their intentions to kill them. As a result, two of its members were captured and other two were killed by Albedo and Mare Bello Fiore to keep the affair a secret. After the incident, it later was made public knowledge that Kralgra perished during the fight between Momon and Honyopenyoko.
Kralgra was composed of a four man team that appeared to have been adept at using hand signals to communicate silently.
