My Unique Skill Makes Me OP Even at Level 1

Ryota awakens in another world, dropped by a slime that a girl named Emily had killed. Emily is strong, but her drop rates are pathetic, so she doesn't earn enough to afford a home. So, since Ryota's drop rates are through the roof, he decides to help.

A bunny girl named Eve attacks Ryota, but he survives thanks to his enormous HP stat. Then Eve reveals that the real reason she came to him was because she saw him getting carrots from a dungeon, and she wants some.

Ryota and Emily decide to try out the second level of the dungeon Nihonium for some new drops, but Emily has a problem with the monsters they find there...

Ryota's skill has proven so profitable that he decides it's time to move into a new home with Emily. But then he learns about magic carts, which can help him carry even more items out of dungeons, and sees an opportunity for even greater profits.

A magic storm occurs, nullifying all magic and leaving magic-based adventurers powerless. But Ryota learns of one magic user who's stuck in a dungeon, unable to fight, and volunteers to help her when no one else is willing to take the risk.

Ryota obtains a second gun, which helps him discover a powerful new use for his special bullets. His exploits catch the eye of Secro's dungeon chief, who has a favor to ask of him...

A new dungeon has been discovered right between Secro and the neighboring city of Hetero. The battle is on to determine which city will claim ownership of the dungeon, and both sides will use any trick in the book to win.

The dungeon master of Selen has appeared, and the dungeon is deemed off-limits until it is defeated. Only a party of three adventurers with very high stats may challenge the powerful dungeon master, but Ryota has a plan...

Since Ryota left for Selen, Eve has been unable to find enough of the carrots she loves so much. She's overjoyed when he finally returns to Secro, but Ryota thinks it's time Eve started getting her own carrots.

A young adventurer named Alice is looking for a party to join, but because her max level is only two, no one wants her. Only Ryota is willing to give her a chance. As he's helping her raise her stats, he learns she has a unique skill of her own...

The harvest festival has begun, and the main event is the creation of strays for courageous adventurers to battle. Naturally, Ryota decides to participate in hopes of winning the rare item reward.
