Evolution

is a process when a Yo-kai changes into a different form. The evolution process can make it much stronger than it's previous form and it will also gain an increase in Rank and power.

Overview
The Evolution of a Yo-kai is done through levelling them up, or fusing them with other Yo-kai or Items.

Yo-kai that evolve via levelling up can cancel their evolution as well, but they will evolve following the next level up.
