Nene Azami Extra Quality -
Nene is the twin sister of Karen Dan, and together they are the Monster, Hachiman Hikigaya and the "I" character. Their role is to serve as a "cure" for Hikigaya's "anti-Hero" state.

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.
