I, who simply loved collecting things, was summoned by Lucile, the Demon Lord's daughter, to gather items known as the 72 Treasures.

However, halfway through her explanation, I accidentally absorbed the Demon Lord's power into my body and gained immense power. With that power, I acquired the ability to create items from raw materials: Item Create.

Becoming a retainer to a slightly clumsy female hero, winning over the Demon Lord's daughter with chocolate, and arranging monsters in dungeons keeps me extremely busy, but my immediate goal is to acquire every single item!

Conquering all 862,139,218 types!

Running a shop, farming with kobolds in a dungeon, becoming a blacksmith and crafting original weapons, being targeted by other Demon Lords, almost being killed by food (?), fighting giant whales and colossal trees, transforming into a woman and being revered as a saint, collecting finger puppets, and embarking on the salvation of an orphanage — this is my item collection story, packed with endless activity.

Of course, I grow stronger through my item cheat ability, eventually becoming powerful enough to defeat even a Minotaur with just my pinky finger.

All five volumes are now on sale and highly acclaimed (e-book versions also available!)

Main story concluded.
