Nene Azami Extra Quality -
Wait, the term "Extra" in Monster Tale is specific to the series' mechanics. Each character has an "Extra," which is a special ability they can use. For example, Karen Dan has her "Monstrosity," which allows her to take on the form of monsters, but that's part of her "Monster" state, not her Extra. Hikigaya's Extra is called "Anti-Hero," which gives him a defense boost when attacked, and it's tied to Karen's Monster state.
