The term "canon" refers to all story elements that are officially part of the original plot as created or approved by the original author. Canon events contribute directly to the main plot, character development, and world-building.
In simple terms: If it happens in the manga (or original light novel) and is faithfully adapted into the anime, it's considered canon.
