Humanity is currently still in the dominion of the gods. With the gods' Dominion, the gods have gracefully given the parts of their Divine Power to help humanity defeat their common enemy. The 'Divine Gifts(Graces)'.

With the Divine Gifts, humanity possesses great Divine Power that could help them defeat the Demonic army and their monsters making them able to tip the scales of the battle despite their frail mortal nature.

With the norm of using Divine Gifts, humanity began to create many organizations and cultures that allowed them to utilize their gods' power, and one such organization came from the country of Trinia, an organization known as the 'Hunter Association'.

The Association where humans could Raid the Demonic Dungeons, by teleporting themselves via Gates, a dimensional portal between realms, controlled from their respective Earthly Divine Pantheons. With the Raids, humans take everything that the Demonic Dungeons have to offer, from Gold, Weapons, and artifacts, even capturing some of the monsters to be legally taken back as prospects and profits that they could use to climb up their ranks in the Association, attaining more wealth and fame as well as the favor from their Gifter Gods.

Alas, as we're talking about these Hunters, there is currently one Hunter that we'll be going to look into for today. 

...

"Ragna Orion 'Miraikuru'* Kent. A twelve-year-old B-Rank Hunter, who lost his power after doing a certain mission in the past. Despite his loss of power, the Association still grants him the B-Rank due to several factors, such as his past achievements, his potential due to his young age, some connections he had in the past, and some side hustle missions he did in these current times with his loss of strength, and that was...

" 'Bait Missions', again!? " said the boy Ragna Kent who sees what mission the Hunter Association Mission Administrator had to give him.

" Sorry about that, Mr. Kent... "
