Considered a weakling his entire life, novice adventurer Lloyd leaves his village located at the fringe of the mortal world to fulfill his dream of becoming a soldier. When he arrives at the capital, the people discover that this oblivious kid from hard knocks might be more powerful than anyone expected.
Both animes are similar I recommend you check the other one out if you like t they both have good storylines and are both airing.
Recommend because it gives a feel like one punch man , animation is not bad and story is also good
Both anime have op main characters, both also have harmen even though it is not listed on Suppose a kid from the boonies moved to a starter town.
They both have a similar vibe and while the characters are vastly different and refreshing, they go hand in hand (idk im just bullshitting here)
Our band of bold adventurers has just blown through the 18th level of the world's most fearsome dungeon, so what do they do for an encore? Since the city of Orario doesn't have a theme park, the next choice for Bell, Hestia, Lilly and the gang would seem to be a trip to the hot springs… and, conveniently enough, a battle with some hellhounds has led them to an undiscovered underground oasis! However, there's something fishy about these springs, beyond the fact that Hermes happens to have bathing suits for all the ladies in their correct sizes! Will the secret be discovered before it's too late? Will Hestia finally come clean with Bell? It'll all come out in the wash when our heroes learn the answer to: IS IT WRONG TO EXPECT A HOT SPRING IN A DUNGEON?!!
After inadvertently managing to kill the god Verethragna, taking his divine powers in the process, the once-typical teen Godou's life changed forever. Now a "Campione", a god slayer, the boy constantly attracts both gods' and other Campiones' attentions alike, not to mention the affections of a powerful knight, Erica. Whether he's dodging Erica's advances, proving his strength to others or taking down gods who will wreak havoc on the planet, Godou's new life is anything but normal.
A young man dies in a car accident and is reborn in a magical new world. The old, yet wise Merlin finds the boy, names him Shin, raises him from infancy, and teaches him combat and powerful magic along the way. 15 years later, Shin is ready to travel the globe on his own, but Merlin forgot to teach him something major—common sense!
High school student Michio Kaga, while wandering aimlessly through life and the Internet, finds himself transported from a shady website to a fantasy world — reborn as a strong man who can use "cheat" powers. He uses his powers to become an adventurer, earn money, and get the right to claim girls that have idol-level beauty to form his very own harem.
Far from the dungeon beneath Oraria rises a new threat, one the beautiful goddess Artemis has sworn to destroy with the help of her chosen warrior. But this fighter isn't the renowned Ais Wallenstein or another storied hero of Orario legend. Instead the fate of Artemis' quest falls upon the shoulders of Bell Cranell, who must partner with the goddess and stand against the menace lurking in the remains of a distant, ancient city. Although Bell is the ordained champion of Artemis and a member of the goddess Hestia's familia, their adventure will test every skill and take every ounce of courage that Bell has — and perhaps, along the way, turn him into the hero he has always aspired to be.
