A parody of fantasy isekai (alternate world) anime/manga stories...

Gamaken Kuronuma is an ordinary Japanese high school student whose life takes an extraordinary turn when he ends up getting hit by a truck. Due to his noble deed in saving the life of his classmate, Gama is reincarnated in the sword-and-sorcery world Enchancia where fairytale characters are real.

Reborn as a baby, Gama discovers he’s the newborn prince of Mithlond Kingdom and decides his life is finally looking up. However, a prophecy that foretells the Goblin King’s death at the hands of King Brandr’s son provokes the monster into trying to kill Gama.

Thanks to the protection of the Blue Fairy, Gama manages to barely escape the assassination attempt with his life. The Goblin King is only able to curse Gama by turning him into a frog. The only way to break the curse is for Gama to get a princess to fall in love with him and bestow upon him true love’s kiss.

It’s in that moment Gama realizes he’s been reincarnated as the Frog Prince. After being forced to flee his home, Gama enters the nearby Forest of Gloom where he soon discovers he possesses magic and abilities that are eerily similar to a video game’s. Suddenly, Gama’s nerdy knowledge of anime, video games, dating sim games, and gal games comes in handy as he faces off against the most dangerous and deadly monsters in all the land.

With the help of his trusty stat window, er, fairy attendant, Henry, Gama does his best to get stronger by killing monsters and leveling up. Eventually, Gama gains enough power where it’s safe enough for him to leave the forest, and he encounters a princess. Unfortunately, things don’t exactly go as planned and Gama ends up with a half-broken curse.

By day, Gama is a handsome prince, albeit with green skin. At sunset he transforms into a slimy, green frog. Gama sets out on a quest to kill the Goblin King in order to break his curse. Accompanying him on this journey is the cursed princess Odette, who turns into a swan at night and is a bird-beaked woman by day. Odette’s maid, Meddie, has been cursed with snakes for hair, but Gama thinks they’re cute.

Later, bunny priestess Usagi, who has been cursed with insatiable lust joins their party. The cure to her curse happens to be passionate kisses from Gama. All of a sudden, Gama begins to wonder when he accidentally began to form a harem of beautiful and otherworldly ladies....
