Mu Yue did not draw immediately. Instead, with a strong sense of ritual, he burned incense and took a bath before clicking extract.
Ninjutsu Extraction Scroll consumed. Obtained skill—Transform (Mastery level)
Seeing the name of the Ninjutsu, Mu Yue froze for a moment. Fortunately, it did not have the word "Jutsu" after it, or his mindset might have crumbled a little. This was an S-rank Ninjutsu Extraction Scroll, after all. Drawing one of the Three Basic Jutsu would have been too ridiculous.
As the extraction finished, a flood of memories related to the Transform skill entered his mind. Only then did Mu Yue learn its origin—Transform was a localized Ninjutsu version of a skill from the Pokémon world.

The second stage was copying the recorded information into the ninja using Transform. Once that stage was completed, the caster entered the transformed state
