One of the main plot points is the search for Mahiru. This could involve characters splitting up to cover more ground. There may also be a sub - plot about Mahiru trying to escape on his own from the kidnappers' lair. He might use his wits and the knowledge he has about the Servamp world to his advantage. Additionally, the relationship between the characters, especially Kuro and Mahiru, is often explored more deeply during this time. Kuro might have to face his own fears and insecurities as he tries to save his Eve.
A common plot point is the immediate reaction of his friends. They usually go into a state of shock and then quickly shift to determination to rescue him. Another is the discovery of clues. There might be a piece of clothing left behind or a strange symbol at the kidnapping scene. Also, there could be some sort of ransom demand, which would add more complexity to the story.
In many Servamp fanfictions where Mahiru is kidnapped, it often leads to a series of intense and emotional events. His friends in the Servamp world would surely be in a panic. Kuro, for example, would likely be extremely angry and determined to rescue him. He would use his powers to track Mahiru down. Maybe he'd team up with other Servamps or their Eves to form a search party. The kidnappers could be some old enemies who want to use Mahiru as a bargaining chip against the Servamps.
In many Servamp Mahiru x Sakuya fanfics, the theme of redemption can be present. If Sakuya has done something wrong in the original story, the fanfic might explore his path to redemption through his relationship with Mahiru. Also, the theme of power and its control can be explored. As Servamps are related to powers, how they handle their powers in relation to each other and their relationship is something that often appears in fanfics. Another theme could be the idea of family, as the Servamp world has a complex view of relationships that can be related to the concept of family.
Love and acceptance are also big themes. Kuro has his own insecurities and past traumas, and Mahiru's unconditional acceptance of him is a key part of their relationship. Fanfictions might expand on this, showing how their love helps Kuro heal. Additionally, the theme of power and control can be explored, as Mahiru is Kuro's master in a sense, but their relationship is much more complex than a simple master - servant dynamic.
In fanfiction, female Mahiru often shows great courage. She is not afraid to stand up to the powerful Servamps and other dangerous foes. For instance, in many stories, she'll bravely face a Servamp who is causing trouble in the city. She also has a strong sense of justice. If she sees something wrong, she'll do whatever it takes to make it right.
One common plot point is the reaction of his friends. They are usually shocked and immediately start planning a rescue. For instance, Uma might use her pirate skills to track down the kidnappers.

Sometimes, the kidnappers demand a ransom, which leads to a whole new set of problems for the other characters to deal with.
