Maybe Naruto discovers a hidden jutsu. This jutsu could be something that was lost or forgotten in the ninja world. He stumbles upon it during his adventures or training. Once he masters this jutsu, he realizes it has the power to remove curse marks. He then decides to use it on Anko to free her from the burden of the curse mark that has been plaguing her.
In a fanfic scenario, Naruto might remove Anko's curse mark through his unique chakra. His chakra, known for its large amount and purifying properties, could potentially counteract the dark and corruptive nature of the curse mark. He might use a new jutsu he developed or a power-up that he gained during his training.
The removal of the curse mark might also change Anko's personality a bit. Since the curse mark was probably causing her some mental and emotional stress, without it, she could be more positive and open. This could lead to new friendships and alliances within the story. For example, she might start to get along better with some of the other Konoha ninjas who she had a bit of a distance from before because of the curse mark.
Anko's character might experience a shift in her personality. She could become more outgoing and less guarded. The curse mark was like a dark cloud over her, and now that it's gone, she can be more open. She might also start to mentor others, sharing her experiences of having a curse mark and how she overcame it (even if Naruto was the one who actually removed it), thus becoming a more positive influence in the ninja community.
In fanfiction, Naruto might remove the curse seal through intense training. He could focus his chakra in a new way to counteract the dark energy of the curse seal. For example, he might use Sage Mode training to purify his chakra system and gradually force out the curse seal's influence.
The curse mark could make Naruto more cautious. Since it's a dangerous and unpredictable power, he might think twice before acting impulsively as he usually does. For instance, in battle, instead of rushing in head - first, he'll consider the consequences of using the curse mark's power.
Well, one possibility is that Anko would feel a great sense of relief. Naruto might discover some hidden power or ability that was being suppressed by the seal. Maybe it could lead to Anko being able to use new jutsus or have enhanced physical capabilities. It could also change her relationship with Naruto, as she might be very grateful to him for removing the seal.
The curse mark can change their physical abilities. For Sasuke, it might enhance his speed and strength, but also make him more prone to losing control. Naruto, on the other hand, might develop new chakra - related powers because of his exposure to Sasuke's curse mark. For example, he could gain the ability to sense the curse mark's energy better.
The curse mark in the fanfiction could be a catalyst for fem Naruto's growth. It could bring out hidden aspects of her personality. Maybe it gives her access to new powers that she has to learn to control. This process of learning and the physical and mental changes caused by the mark would surely have a profound impact on her character development. She might become more cautious, as she realizes the potential danger of the mark, yet also more bold in her attempts to master it.
After absorbing the curse mark, Naruto's character development could take a significant turn. Firstly, he may face new challenges in controlling his emotions as the curse mark might have an impact on his temperament. He could become more impulsive or aggressive in battle. However, this also gives him an opportunity to grow. He has to learn to harness this new power without succumbing to its negative effects. It could lead to a more mature Naruto as he grapples with this new aspect of himself.
