The only person willing to help Naofumi, the Shield Hero, is Malty Melromarc, a princess of the kingdom. However, she soon betrays him by stealing his resources and falsy causing him of taking advantage of her.

This causes Naofumi to be discriminated against and hated by the people of Melromarc for something he didn't do.

Full of hurt and mistrust Naofumi begins his journey of strengthening himself. He buys the demi-human Raphtalia, a slave on the verge of death. He wants her to accompany him on his travels.

Raphtaliathe is the sword to Naofumis shield.

The Rising of the Shield Hero is a good anime. It's interesting to watch the main character dealing with having everyone against him and growing stronger.

It has an interesting gamelike progression and a decent story and characters.

This anime is not a masterpiece, it's not among the best. It's only recommended if you like anime or like these kinds of Isekai/LitRPG kind of stories.

However, living a normal life is impossible, as he is established as a local celebrity almost as soon as he arrives.

Wise Man's Grandchild is a decent Isekai, transported to a game-like world, anime.

Indeed, their misfortunes have only just begun!

KonoSuba is a popular anime with a loyal fanbase.

It's a very good Isekai Anime with a humoristic twist on the genre.

It has hilarious storylines, lovable characters, and stunning animation.

This universe is about gaming. All conflict and problems are solved by games. No murder or violence is possible.

The premise of this anime sounds a little silly, but the anime turns out to be really good.

If you like anime and gaming, then this is a must-watch.

Momonga is a powerful wizard and master of the dark guild Ainz Ooal Gown int the popular virtual reality game Yggdrasil.

The final hour before the game shuts down for god has come and he decides to stay logged in during this event.

What's even more strange is that all the NPCs appear to suddenly have developed personalities of their own.

Surprised by this strange occurrence, Momonga decides to investigate and take control of this new world to figure out the cause and to see if there are others like him.

I recommend this anime, but only if you like this genre. Its one of the better "trapped in RPG game world" animes.

Kaede Honjou reluctantly agrees to try New World Online after a friend enthusiastically invites her. New World Online is a very popular VRMMO game with thousands of players across Japan.

Kaede Honjou names her character Maple. She is a total noob and afraid of getting hurt, so she puts all her points into vitality. This makes Mapel very hard to kill, but she deals almost no damage and walks very slowly.

Min-maxing to the extent Mapel has done usually ends badly, but she lucks out by gaining powerful skills and items to bolster her playstyle. 

Maple easily acquires some overpowered skills like; Total Defense, Poison Immunity, Devour, and later many more. These skills together with some overpowered items she also acquires make her an overpowered walking fortress that can kill most enemies in one hit.

After only a few days of playing Maple wins third place in an event including all players. This gains her the reputation of being both unkillable and totally overpowered.

Mapel gains infamy and is almost on a path to become a boss character her self. But Mapel is evil or power-hungry. She is kind and happy. All she wants is to play and have fun with old and new friends.

The Bobiverse series is the best sci-fi book series I have read in a long while. 

It's full of references to interesting science and popular culture.

It has a good story with cool humor. It's also very interesting and funny how the different bobs interact with each other.
