In a fanfiction where Naruko gets a tanto, who could be her mentor in using it?

Makarov could be her mentor. He is the master of the Fairy Tail guild and has a vast amount of magical knowledge and experience. He could guide Lucy in exploring deeper aspects of her celestial spirit magic, teaching her how to better communicate with her spirits on a more profound level, which would in turn make her stronger when summoning and using their powers.

One possible plot could be that Naruko discovers the tanto in an old family heirloom chest. She then starts to train with it secretly, knowing that in her world, having an unregistered weapon like this could get her in trouble. As she trains, she discovers unique abilities the tanto has, like being able to cut through certain magical barriers.

It could be an older, more experienced android. One that has been through a lot and has a deep understanding of both the android world and human society.

Imagine if the tanto was a gift from a mysterious stranger. This stranger could be an ally or an enemy in disguise. Naruto would be suspicious but also intrigued. As he tries to figure out the stranger's motives, he also has to deal with the tanto's unique abilities. Maybe the tanto can transform into different shapes, and Naruto has to learn how to control this transformation in the heat of battle.

One idea could be that Naruto discovers the tanto in an ancient shinobi relic site. He initially doesn't know how to use it but with the help of Kakashi, he starts to learn. The tanto could have some special powers, like being able to cut through chakra - based defenses. This would add a new dimension to Naruto's fighting style.

Naruko in this fanfiction is most likely a character that the author has developed for the story. It might be inspired by other characters in the genre or it could be a completely new concept. Maybe she has certain unique abilities or traits that make her the target of being double teamed. For example, if it's in a fantasy setting, she could possess a powerful magic that others want to suppress by ganging up on her.

Maybe Dumbledore in a more in - depth way. In the original series, Dumbledore was somewhat mysterious in his teachings. Here, he could really focus on Harry's growth and give him proper training, perhaps in the art of divination and understanding prophecies better.

Well, it could be that the mentor in 'Connor gets a mentor fanfiction' is someone with a lot of experience in a particular field that Connor is interested in. For example, if Connor wants to improve his combat skills, the mentor could be an expert fighter. The mentor could show Connor new techniques, and also help him develop strategies for different situations. This would not only make Connor stronger but also more confident in his abilities.

Perhaps a mysterious figure who has been observing Sakura from the shadows. This person, for some reason, decides to train her to be an assassin. He could have some ulterior motives, like using Sakura for a grander plan, but still teaches her valuable skills along the way.

Snape is a likely candidate. He is a skilled legilimens in the original series, and his relationship with Harry is already complex. Teaching Harry legilimency could be a way for Snape to either help or hinder Harry, depending on his motives.
