Keima's Summoning

Summoning
While Keima was sleeping, he was summoned to another world. While he was being summoned he met with the God of Light who asked him to take care of dungeons which are disturbing the flow of Mana. But Keima didn't really care, so the Light God half-assedly gave him skills: Language Comprehension and the ability to freely change the shape of Golems.

After he materialized in the new world, he met with Rokuko who summoned him with the dungeon's gacha function, for 1000 Dungeon Points. While they introduced themselves to each other, for unknown reasons Keima became the Dungeon Master of the Ordinary Cave, and with that the Master of a Dungeon Core.

After he became a DM, Rokuko told him why he was summoned in the first place. The dungeon was infested with enemies. A group of bandits who decided to take refugee inside a cave without knowing it was a dungeon. Their leader was a former noble, Waver.

Bandits Extermination
Keima decided to get rid of the Ordinary Cave Bandits. The reason being there is a slight chance of breaking the Core. Which means his death. He decided to give them rewards for being considerate and not breaking the core. After Waver and the bunch realized they were within a dungeon that would give them items, they decided to kill everybody who comes near the cave entrance. After some time adventurers came, and they all were killed.

After this happened a few times the local Adventurer's Guild in Tsia decided to get rid of the Bandits. They issued a quest, and one of the Empire's Knight Platoon, specifically the Seventeenth Knight Platoon came. They got rid of them in a single day. The Knights didn't notice her but, Niku was under Waver's bad the whole. Keima had to hypnotize himself, so could image the young Beastkin as a bodypillow. He succeeded, and since then Rokuko believes that slaves are items, that could be collected through the Dungeon Menu.

With this Keima and Rokuko gained more than 10,000 DP and Niku.
