Yisu was a fan of the Pirate King before he transmigrated.
He thought he knew everything there was to know about the Pirate King, and that he could thrive after transmigrating to this world of great voyages.
Since he knew everything, he passed himself off as a fortune-teller.
But the very first time he set foot on land with Luffy, he realized everything had changed completely.
By the end, he discovered that the pirates appearing in the weakest East Blue were just as powerful as the great pirates of the Grand Line.
Luffy and his crew had yet to grow stronger, but their crisis had already arrived...
It was all for their dreams and the desire to grow stronger. With no other choice, Yisu shouldered the burden and became the crew's instructor.

Looking at the introduction, there is no need to even test the poison. The title character's father is named Luffy.
You are not an instructor, you are a nanny.
