Definitely not. Such stories with sexual content are not suitable for public consumption. They can have a negative impact on the mental health and values of the audience, especially younger audiences. We should focus on positive and family - friendly isekai stories.
Rather than dealing with inappropriate content, in regular isekai stories, the theme of redemption can be quite common. The protagonist may have had a troubled past in their original world, but in the isekai world, they get a chance to start anew and make up for their past mistakes. Also, the theme of building alliances is often seen. As they are in a new and often dangerous world, they need to form alliances with various characters to survive and thrive.
Well, 'That Time I Got Reincarnated as a Slime' is a top - notch isekai story. The main character, Rimuru, is reincarnated as a slime in a fantasy world. He then uses his unique abilities to build his own nation and make friends and allies. It has a great balance of action, world - building, and humor. 'Konosuba: God's Blessing on this Wonderful World!' is also very good. It parodies the typical isekai tropes in a hilarious way, with a group of misfit characters going on adventures in a not - so - ideal isekai world.
One common theme is power acquisition. The main character usually starts from a weak state in the new world and gradually gains power, like in 'That Time I Got Reincarnated as a Slime'.
One popular isekai anime story is 'Sword Art Online'. It's about a virtual reality MMORPG where players get trapped in the game world. Another is 'Re:Zero - Starting Life in Another World', which follows Subaru as he is transported to a fantasy world and has the ability to return by death. 'That Time I Got Reincarnated as a Slime' is also well - liked, where a man is reincarnated as a slime in a different world and builds his own kingdom.
A big trope is the 'fish out of water' situation. The character from the real world has to adapt to the strange rules and customs of the isekai world. Also, there's the 'chosen one' trope. The protagonist is somehow destined to save the isekai world or fulfill a great prophecy. And let's not forget the 'gaining levels' or 'power progression' trope, where the character gets stronger as they complete tasks or defeat enemies.
Well, there's 'Isekai Gamer: The Virtual Reality'. In this fanfic, the main character enters an isekai world that has elements similar to virtual reality games he used to play. It's interesting because he has to figure out how to use his in - game strategies in a very real and often dangerous world. Then there's 'Gamer's Isekai Rebirth'. Here, the protagonist is reborn in a magical world and uses his gaming instincts to become a powerful figure. 'Isekai Gamer: World Hopping' is also a great one where the gamer jumps from one isekai world to another, facing different challenges each time.
Isekai anime stories often offer a sense of power and growth. The main characters usually start from scratch in the new world and gradually become powerful. For example, in 'That Time I Got Reincarnated as a Slime', the protagonist evolves from a simple slime into a powerful being. Also, the unique settings in isekai anime, like the various magic systems and strange creatures, are very attractive.
It can add depth to their relationship and show a more intimate side. Maybe it's a turning point or a way to intensify their connection within the fantasy world.
One characteristic is the transportation to another world. This could be a medieval - like fantasy world, a post - apocalyptic world, or even a world based on different rules of magic or technology.
