Tomas Chavez, a Filipino high school student from Roxas, Oriental Mindoro, the Philippines, died by Truck-kun and was reincarnated into a seemingly normal fantasy world with a new body and identity. He was known as Karolo Sala. That new world had some practical technologies while retaining its medieval and fantasy style. 
  But settling down was not possible due to a war known as the Curse War, which was ongoing. That war is between the summoned 4 Horsemen, who were summoned by a shady organization known as the Order of the Deathcallers, and the humans. The same organization also brought death to those who, unfortunately, became their targets and victims. The world was in chaos, and Karolo was so unlucky after mistakenly settling down in a city known as Darkhtan, in the country called Steein in the Central Territory. 
  While in the middle of the war and fighting, Karolo got involved and was killed by two of the many Deathcallers, the siblings Dan and Vanda Ciercello. These two, who had a sad childhood, realized what they did to him and those who got involved in the fighting and decided to abandon their duties to the Order and save Karolo from death. However, the wounds proved to be too severe and deep for their healing magic to do the work. So, Dan decided to use a magical technique called Healing of Repentance. It is a rare technique that would heal any physical or mental ailments, but this will cost them one thing: their loyalty. This means that once that was being used, Dan and Vanda will be loyal to Karolo, for a week. But Dan and Vanda will do anything to bring Karolo back to life. And…they did so, and Karolo was brought to life. Dan and Vanda then apologized to him and vowed and swore their loyalty to him to atone for their sins of bringing atrocities to humanity. 
And so, the three of them worked together to end the war to bring peace to the world again. And they did so, and the Curse War ended with the bad demons wiped out of existence and the Summoned 4 Horsemen returned to the Realm of the Fires. But the story of their new lives was just starting after the war had ended.

 The tide of the war turned. Hiroto, Lakshay, and the Lightness Church soldiers charged in at the OD and the 4 Horsemen. The Four Horsemen had these colours:


 Karolo and his team, meanwhile, are still in their counterattack against the OD. Karolo fired his guns and hurled grenades. With his pistols broken from a spell attack of a Deathcaller, Dan grabbed a discarded shotgun and started shooting the OD soldiers. The other Deathcallers were angrier than before as Vanda slashed one Lead Rainer soldier with her Deathcaller Sword like butter. Meanwhile, a sapphire blue owl was watching the fight from the sky. It was a beast known as the Sapphire Owl, a wild familiar.


It was a he, who could shrink or expand his size, and was as fast as a Shinkansen; his pecks are powerful.


 Meanwhile, Hiroto, Lakshay, and the Lightness Church soldiers are doing the Spell of Banishing on the Four Horsemen as Karolo and his team, as well as the Steein soldiers, provide cover for them from the OD.
