One good Naruto and Kankuro non - lemon fanfiction could be 'The Bond Beyond Villages'. It focuses on their friendship development as they team up for a mission that affects both their villages. In this story, they start off with a lot of misunderstandings but gradually come to respect and rely on each other.
One main theme is friendship. Naruto is known for his ability to befriend people from different places, and with Kankuro, it's no different. Fanfictions often explore how they form a bond, like in 'The Kankuro - Naruto Friendship Arc' where they go through various trials together that strengthen their friendship.
Well, a common pairing is Kankuro and Sasuke. Sasuke's brooding and powerful nature can be an interesting match for Kankuro. The two could be pitted against each other initially and then develop feelings over time. Also, Kankuro and Neji have been paired in some fanfictions. Neji's calm and composed self paired with Kankuro's more flamboyant personality can make for some unique stories. Additionally, Kankuro and Kiba is a pairing that exists. Kiba's wild side and love for his dogs combined with Kankuro's puppet skills can lead to some fun and exciting yaoi fanfiction scenarios.
A frequent theme is the exploration of the forbidden. In the context of Naruto Shippuden, yaoi relationships involving Kankuro can be seen as going against the norm. So, fanfictions might focus on how he deals with this. There could also be themes related to family reactions. How would his family, like Gaara, react to his relationship? It adds an extra layer of drama. Additionally, the theme of perseverance in love is common. Kankuro and his partner might face numerous obstacles, but they persevere in their relationship, showing the strength of their bond.
One idea could be that Sakura uses her medical ninjutsu to heal Kankuro after he gets seriously injured in a battle against a powerful enemy. She has to overcome various challenges like limited supplies and the unique nature of Kankuro's puppet - related injuries.
A plot twist could be that the method Sakura uses to heal Kankuro has an unexpected side effect. For example, it gives him a temporary boost in his puppet - using abilities that he has to quickly learn to control.
One plot could be that Kankuro falls for a healer in the village. She mends his wounds after a battle. He is attracted to her gentle nature. They spend time together as she teaches him about herbs and he shows her his puppets. Their relationship blossoms from there.
One interesting thing is how their personalities might be explored in fanfiction. Kankuro is often seen as a bit of a trickster, while Tenten is determined. Their different traits could lead to some engaging storylines, like Tenten trying to get Kankuro to take things more seriously, or Kankuro teaching Tenten to be more flexible in her thinking.
I'm not sure specifically about 'gaara and kankuro lemon fanfiction'. Fanfiction can vary greatly in quality and availability. You could try searching on popular fanfiction websites like Archive of Our Own or FanFiction.net. However, make sure to abide by their terms and conditions.
Perhaps Kankuro meets a fellow puppeteer. They start competing with each other at first, trying to outdo one another in puppet - making and shows. But during this process, they realize they have a lot in common. Their shared passion for puppetry leads to mutual admiration and then love. They create beautiful puppets together, symbolizing their relationship.
