When you, a fallen Angel, were alone during the apocalypse, your mother, known as Monna Diabloson, thought you were believed to be taken away from her, she was released from Hell alongside other demons where they proceeded to either corrupt or slaughter unfortunate humans who caught within their path for destruction while trying to look for you.

Though her presence can be felt throughout the entire event with your mom's demons ravaging the world looking for you, Monna doesn't make her debut until she finally appears before you escape from savages on earth during the apocalypse. You first notice the Earth trembling from your mom's footsteps before seeing him towering over the distant buildings and she's looking for you. Monna worriedly cries out for you saying in a booming, thunderous echo: "MY LITTLE ANGEL! WHERE ARE YOU!?!" You see your mom in the distance utter their shock at her sheer size and disorientation from the shaking as she spotted you in the distance alone and she screams "THERE YOU ARE, MY BABY!!!" She walks toward you, up until Monna takes her final step, collapsing a nearby overpass. When your mom lowers and picks you up in her gigantic hand, you begin apologizing to her.

Fortunately, your reconciliation and admission of isolating yourself from your home in The Wrath Ring in Hell, she knows why you were on Earth by yourself, likely that she was having a bad day. So, that's why you left Hell so she can have some time to cool down.

Suddenly, your divine beam appears right before she can take you back home to The Wrath Ring in Hell. The appearance of the beam causes Monna to recoil, sending her falling onto her back and sending up an immense cloud of dust.

At first, you told God that the only reason why Monna, the devil incarnate/gender swapped version of The Devil herself is on Earth causing Doomsday and Armageddon by sending her minions to look you is because of you. Monna rises back to her full height right about when you are eye-level with her. And you told God that you're the only one who can stop her, not by fighting her or killing her, but to go home to her with her. And that's what you're gonna do right before your divine beam disappears on you before plummeting into Monna's open hand as she catches you safely.

Fortunately for Monna just as he was about to take you back home to Hell and calling off the apocalypse. To add a surprise to injury, when she begins to take you home, she trips and falls forward and clenches her fist tightly so she can protect you safely. As Monna collapsed to the ground while keeping you safe. Her tail collapses onto a parking garage (which the organ easily overtakes in length), demolishing it instantly and shaking the Earth.

The Queen of Wrath herself gets herself back on her draconic feed. She is still holding you in one hand and noticing that you're still intact. Since she still survived this mishap, Monna cancelled her rampage and likely took you home to the Wrath Ring and ended the apocalypse, calling her minions to return to Hell.
