Another theme is the discovery of self - worth through love. The oc characters often start out with insecurities or a sense of not belonging. But through their relationship with Kirito, they learn to value themselves more. For example, an oc might think she's not strong enough in the game, but Kirito makes her see her own unique qualities.
A common theme is adventure. Since Kirito is known for his adventures in the virtual world, these fanfictions often have the reader joining him on exciting quests. Another theme is romance, of course, showing the relationship between Kirito and the reader.
There are several common themes. First, there's the theme of unrequited love or the slow - burn romance. Sometimes Sachi has feelings for Kirito that she's afraid to show, or it takes a long time for them to realize their feelings for each other. Second, there's the theme of sacrifice. Sachi might be put in a situation where she has to sacrifice something for Kirito, or vice versa, which tests and deepens their relationship. And of course, the theme of adventure is also common as they are in a virtual world full of quests and challenges that they face together.
Friendship is a common theme. Their bond as comrades in the virtual world is often explored, like how they trust and depend on each other in battles.
One common theme is the exploration of gender - reversed dynamics. Since Kirito is usually male in the original, seeing how a female Kirito interacts with Asuna brings a fresh perspective. Another theme is the strengthening of their bond. These fanfictions often focus on how their relationship grows deeper in different situations.
The theme of redemption is also quite prevalent. The rake might have a past filled with bad behavior or mistakes. Through the relationship with the OC, he gets a chance to make amends and become a better person. Also, the exploration of new emotions is a big part of it. Since the rake is often portrayed as a bit of a playboy, experiencing true love with the OC is a whole new and sometimes scary experience for him.
One common theme is the discovery of new emotions. Ellie might be a complex character, and the OC often helps her explore feelings she didn't know she had. Another is the idea of two different worlds colliding, especially if the OC has a different background than Ellie.
One common theme is the power of love in a dangerous world. Since Minato is a shinobi, his relationship with the OC often has to navigate the perils of the ninja world. Love can be a source of strength for both of them.
A frequent theme in these fanfictions is the exploration of new identities. Kirito, being in a different world, has to re - define himself, and the Fate characters also see him in a new light. Teamwork is another big theme. They have to work together to face the challenges of the Grail War or other threats in the Fate world. And of course, the theme of heroism. Kirito's heroic nature from Sword Art Online and the heroic ideals in Fate/stay night are often compared and combined in these stories. For example, in some fanfictions, Kirito takes on the role of a hero in the Grail War, much like the Servants in Fate/stay night.
One common theme is adventure. Since they are from the Sword Art Online universe, they often go on quests together in fanfics. Another theme is love, as their relationship is a central focus. It can range from a budding romance to a deep and abiding love.
Adventure is also a popular theme. Since they are in a virtual world in Sword Art Online, fanfics may take them on new and exciting adventures that were not in the original plot.
