Perhaps in a fanfiction, Summer discovers a hidden portal that leads to the Naruto world. There, she meets Naruto and realizes that his experiences with loss and his determination to protect his friends are similar to hers. They form a bond and work together to help a group of ninjas who have been affected by a strange phenomenon that is causing their powers to go out of control. This phenomenon might be related to the Grimm from the RWBY world.
Obviously, Summer and Naruto would be the main focuses. Summer, with her skills and backstory from RWBY, would bring her own set of abilities and relationships to the story. Naruto, on the other hand, is full of energy and has his powerful ninja techniques. Their interactions would be central to the fanfiction.
A common theme is the clash and fusion of different powers. Naruto has his chakra - based ninjutsu and Summer has her own combat style. Fanfictions often explore how these powers can be combined or used in new and interesting ways.
The plot might involve Adam struggling to adapt to his new life with Summer. He could be initially resistant to her kindness, thinking it's a weakness.

One popular 'naruto x summer rwby fanfiction' might be those that focus on how Naruto's unique ninja abilities interact with Summer Rose's combat skills from RWBY.

I've read a fanfic called 'RWBY's Summer with a Ninja'. In this one, the RWBY characters meet Naruto during a summer mission. It's a short but sweet fanfic.

The description of the summer landscape in the RWBY world along with Naruto's presence makes it an enjoyable read.
The plot could center around Summer's return and how it affects the current state of affairs in the RWBY world. Maybe she comes back with new powers or knowledge that she imparts to the other characters. It might also deal with the emotional impact of her return on her family and friends, especially Ruby who has grown up without her mother for a long time. There could be battles and challenges that Summer has to face as she reintegrates into this world, and she might be a key factor in solving some greater threat that the RWBY characters are facing.
A possible plot could be that Velvet has a unique power that is recognized by both the RWBY and Naruto universes.

So, she gets transported to the Naruto world to help, and along the way, she forms bonds with Naruto and his friends. When she returns to RWBY, she has new skills and a different perspective.
One possible plot could be that Naruto somehow gets transported to the RWBY universe. He teams up with Neo.

Well, it could be that Naruto somehow gets transported to the RWBY universe and has to deal with the Grimm. Maybe he uses his ninja skills to fight them off. For example, his shadow clone jutsu could be used to confuse the Grimm while he attacks from another angle.
Well, if Naruto reincarnates in RWBY fanfiction, he could change the power balance in Remnant. His ability to use Rasengan and other powerful jutsus would make him a formidable force.
