The world - building is crucial. A good op isekai novel needs a vividly described fantasy world. You should think about the rules of this world, the different races and species, and how magic or special powers work. This will help set the stage for the OP character to shine. Also, include a strong plot. There should be challenges for the OP character to face, even if they seem unbeatable at first. Maybe they have to deal with political intrigue or a powerful enemy that can match their strength in some ways.
Finally, consider the character development. Just because the character is OP doesn't mean they can't grow. They could learn new skills, gain more wisdom, or develop their relationships with other characters. This will make the story more engaging and the character more relatable, even if they are super - powerful.
One popular isekai op novel is 'Overlord'. In this novel, the main character is transported to a different world with extremely powerful abilities. He has to navigate this new world while being almost overpowered compared to the native inhabitants. Another great one is 'Tensei Shitara Slime Datta Ken'. The protagonist, reincarnated as a slime, quickly gains OP (overpowered) abilities and builds his own nation in the isekai world. There's also 'No Game No Life' where the siblings are transported to a world ruled by games and they possess incredible skills and intelligence that make them OP in this new realm.
To write a good bl isekai novel, start with a strong concept. Decide where your characters will be isekai - ed to, whether it's a fantasy land or a parallel universe. Make sure the bl aspect is well - integrated. For example, their love could be the key to solving problems in the isekai world. Moreover, add some twists and turns in the plot to keep the readers engaged. The relationship between the two male characters should grow and change as they face different challenges in the new world.
Well, 'Sword Art Online' can also be considered in a way. Although it's not a pure isekai in the traditional sense as the characters are trapped in a virtual world. But Kirito, the main character, becomes very OP as he progresses through the game world. He has excellent sword skills and adapts quickly to different situations.
The theme of harem or multiple relationships also exists in some 'op isekai light novel'. The OP male protagonist often attracts female characters. In 'In Another World With My Smartphone', the main character has multiple female companions around him. This adds a romantic or relationship - based sub - plot to the overall story of the isekai adventure and power growth.
Another common theme is the fish - out - of - water situation. The MC is transported to a new world, so they have to adapt to new cultures, magic systems, and social structures. In 'Konosuba', Kazuma has to deal with all the crazy things in the isekai world while trying to make the best of his situation with his OP party members. And they often have a goal, like saving the new world or finding a way back home, which drives the story forward.
One popular 'isekai op character light novel' is 'Overlord'. In this novel, the main character Momonga is extremely powerful as he gets transported to a new world. He has the abilities and knowledge from his previous gaming life which makes him OP in the new world.
Another great op isekai novel is 'That Time I Got Reincarnated as a Slime'. The main character, Rimuru, starts as a slime but quickly gains extraordinary powers through various means like consuming other creatures and making allies. His OP nature makes for an exciting story as he changes the world around him.
Well, one common theme is the exploration of the isekai world itself. The OP characters often go on adventures, discover new places, and uncover secrets. Another is the concept of relationships. They form alliances, make friends, and sometimes enemies in the new world, and these relationships are shaped by their OP status. Also, the theme of challenging the status quo is present. Their OP abilities give them the power to change things in the world they are transported to, whether it's the political system or the way magic is used.
The genre also often features elements of self - discovery for the MC. Despite being overpowered, they still need to figure out their place in this new world. They may face moral dilemmas, form relationships, and learn about the history and secrets of the isekai world. This combination of OP abilities and personal growth in a new and strange setting is what makes the 'op mc isekai light novel' genre so appealing to many readers.
A sense of isolation or being different is also common. Because they are OP, they might not be fully understood by the natives of the isekai world. In 'Re:Zero − Starting Life in Another World', Subaru has his own set of powers that make him unique, and he often feels isolated as he tries to make sense of his situation and use his OP ability (return by death) to his advantage.
