Death Angel Z-Onel (死霊妖精クオリネム Shiryō Yōsei Kuorinem, Death Fairy Quarinem) is a Zombie variant of Cruel Angel Clionel appearing in the Advent StageZ-Onel Rises!.
At first glance, she seems much weaker than other Advent bosses, having merely 1,000,000 health and a large blind spot. That is until you realize her powerful gimmick and synergy with the enemies in her debut stage. First, her bigger piercing range and slow movement only prove annoyance with a guaranteed freeze posing a huge threat. Even with her much lower health, if she is killed by non-Zombie Killers, she can revive quickly and infinitely. What makes it all much worse is the fact that Z-Onel's debut stage includes two of them, making the stage arguably one of the hardest Advent Stages.
The Clione family was supposed to be wiped out by sea pollution.
A being formed from remains who stands in front of her loving children no matter how many times she's defeated.
Able to stop the movement of those who approach her blind spot.
