Well, perhaps they meet in a crowded city street. Shion is running late for an important meeting and accidentally bumps into Kiyoki, causing them to drop their things. As they pick up their belongings, they start chatting and realize they have a shared interest in art. This could lead to them visiting art galleries together and becoming good friends over their love for different artworks.
They could meet in a library. Shion is looking for a very rare book and Kiyoki happens to be the librarian's assistant. Kiyoki helps Shion find the book and in the process, they find out that they both have a passion for old, forgotten stories. They then start to exchange their favorite tales and form a bond based on their mutual love for literature.
In this fanfiction, Shion and Kiyoki are likely two characters created by the fanfic author. They could be based on certain archetypes like Shion might be the more adventurous type, always looking for new experiences. Kiyoki, on the other hand, could be more reserved and calm. But when they meet, their personalities start to complement each other.
One idea could be a story where Naruto, Hinata, and Shion have to team up to protect the Hidden Leaf from a new and powerful enemy. Shion could use her unique powers, Hinata could support with her Byakugan and gentle fist techniques, and Naruto would be the main force with his Nine - Tails chakra.
One idea could be that Naruto and Shion travel back to the founding of Konoha. They could use their modern knowledge and skills to help the early founders avoid some of the future problems. For example, they might be able to prevent certain clan rivalries from getting out of hand.
One interesting plot idea could be Shion having premonitions about Naruto's future challenges as Hokage and they work together to prevent them. Another could be that Shion is in danger and Naruto has to use his new - found powers to save her. It could also be a story where they go on a journey to discover a hidden power that only they can unlock together.
One possibility is that Shion and Yuki are from different clans in the Naruto world. Their clans have some sort of feud in the past. But when they meet, they realize that they have more in common than they thought. They then try to bridge the gap between their clans while also dealing with the overarching threats in the Naruto world, such as the Akatsuki.
A plot could involve a group of Hogwarts students accidentally ending up at Ilvermorny and having to adapt to the new school's rules and culture while also trying to find their way back home. It would be a story of discovery and friendship as they interact with the Ilvermorny students.
Well, perhaps there's a plot where the iCarly gang goes to Hollywood Arts (from Victorious) for a special project. Sam could get into some hilarious prank battles with Jade, while Freddie tries to film the whole chaos for a new iCarly episode. And Cat could teach Gibby some really wacky dance moves.
One idea could be Boruto getting transported back in time and meeting a young Naruto. He could then help Naruto avoid some of the early hardships he faced, but also realizes that those hardships made Naruto who he is. Another could be Naruto and Boruto switching bodies for a day, which would lead to humorous situations as they try to navigate each other's lives. A third idea might be that Boruto discovers a hidden power within himself by training with Naruto in a special dimension where time moves differently.
In this fanfiction, it could be that Hela is in need of something that only Harry can provide. Maybe a magical item from his world that has the power to heal a wound she got in a previous fight.

Another plot could be that Casper and Wendy get into trouble when they accidentally break a major rule in the ghost world.
