I'd recommend 'The Secret Mission of Makino and Shanks'. This fanfic has exciting action scenes and a touching emotional core. The author does a great job of capturing the essence of both characters.
I'm not sure of specific Shanks and Makino baby fanfictions off - hand. But you could try searching on popular fanfiction websites like Archive of Our Own. They have a wide range of fan - created works and you might be able to find some interesting stories about Shanks and Makino having a baby there.
One popular Shanks x Makino fanfiction might be 'A Pirate's Promise'. It often delves into their relationship, exploring how Shanks' pirate life intersects with his feelings for Makino. It has great character development and some really touching moments.
Perhaps a plotline where the baby grows up in the care of Makino while Shanks is away at sea. The story could show the baby's longing for its father and how Makino tries to keep the memory of Shanks alive for the child. As the baby gets older, it might start to show an interest in following in Shanks' footsteps, which could create some interesting family dynamics and internal conflicts for both Makino and the child.
One common theme is the long - distance relationship aspect. Since Shanks is a pirate out at sea most of the time, the fanfictions often explore how they maintain their connection despite the distance. Another theme is unrequited love, where sometimes one of them is pining for the other while the other may not be fully aware.
There are several great ones. One that comes to mind is 'The Secret Love Affair' which has a unique plot and well-developed characters.
