Within the dark forest, where the trees and a flow of river made of light, where the sky is scarlet, where clouds floating, where a crescent moon hanging on the above and dozens of ravens with three-glowing eyes standing on the perches of the tree branches observing a female figure running away from the creatures that was chasing her.

*Pant. . . pant. . . pant. . . pant*

That young woman is Kaguya (1), High Priestess of Thorn and a Shield Princess of the Seven Shield Alliance, she has black bob cut short hair and amber eyes. Her miko clothe are in tatters, her breasts are expose as it bounces, and her legs expose as well. She was running away from her pursuers; she hears their loud laughter and she keeps running. Her pursuers are humanoid dogs whose furs are black of the night and eyes are glowing red are running in fours, and humanoid insects with different shapes flying above, as they keep chasing her with lust.

Until one of the black dogs pinned her down on the ground, while the rest of the pursuers surrounds the pinned down priestess and look at her with lust in their eyes, the alpha black dog that holds Kaguya as it opens its mouth and sticks out its tongue then licks down her body which made her disgusts as she tried to get off the creature, but no avail, she sees the black dog's rod was about to inserting her vagina as she close her eyes of her fate.

Then suddenly sound of a loud roar, a roar of a creature that was heard in the dark forest which made Kaguya's pursuers stopped of what they're doing as they tried look around of the source and they heard flapping wings as they look in the sky which made the fallen priestess' eyes widen in awe and frightened that the appearance of a dragon, a RED DRAGON with crimson majestic scales and she's flying her wings above as it looks at Kaguya's pursuers with DISGUST and ANGER, and showing its fangs then roar at them again.

The humanoid insects fly towards the dragon, but they met bursting of flames coming from the dragon's mouth. One of the surviving humanoid insects tried to escape, but the dragon used its speed to cut them to chunks as it fell down on the soil.

The red dragon lands in front of them, as its purple eyes looks at them that pierce Kaguya's pursuers' souls as they back frighten, but the alpha growls at them to stop and points the red dragoness to attack, since they didn't want to disobey their alpha's commands and began charging at the red dragon. Dozens of black dogs surround the red dragoness and jumps her, but with a smirk on her, the dragon readies its claws and its sharp pointed tail then the dragon spins around like a tornado that cuts them to chunks of meat. Only five remaining black dogs including the alpha, the red dragon raise its claws and made a taunting manner 'come and get me' that fumes the alpha's anger as he and five remaining black dogs charge blindly which the dragon dash forward to the black dogs and they become chunks of meat.

The red dragoness pins the alpha black dog with her claws, as its snarling its defiance, but the red dragon dive down and bites down with a whimpering death of the alpha black dog which made Kaguya close her eyes and for a minute, she feels breathing and she opens her eyes that the red dragon looking at her curiously. At first, she was frightening of the red dragon's appearance, but when she looks at dragon's purple eyes with gentle and kindness. Kaguya raises her delicate hand and touches the red dragoness face, she feels warm and calm then she hugs the dragoness, as the dragon's body began to glow of bright light which made her back away and covering her eyes with her arms and when the light began to fade.

She lowered her arms and she was shocked of what she was seeing that in front of her savior is a woman standing there, her hair is bright scarlet, her purple eyes, red metallic bra covers her bust, red loincloth, two horns on her head with golden ring accessories, red shoulder pads on her shoulders, red light gauntlets, and her wings.

Kaguya's cheeks started bright, as she keeps staring her savior's beauty. The humanoid dragoness walks in front of her and looks at her amber eyes, she lifts the priestess' chin and she press her lips on Kaguya's lips which made her respond by kissing her savior and she hugs the dragoness, the scarlet dragoness lifts Kaguya's buttocks which made her yelps a little as she resumes kissing her dragoness savior and wraps her legs on the dragoness' waist, then she felt something entering her vagina as she detaches her dragoness' lips and made a moan.

"Oooooooooohhhhhhhhhh~!"

Kaguya's room, Fortress City-State of Thorn

Kaguya's eyes opens as she rose up in sweat, she stands up from her futon and she slides the door open and walks outside then she looks at the crescent moon hanging in the sky. Kaguya lifts her finger on to her lips remembering her kiss of the dragoness, her cheeks brightens and her heart started to beat.

"Is this what love at first sight feels?" She whispers, as she keeps staring at the moon.

Unaware of her, that her soulmate will be there. . . very. . . soon.

Japan, Earth

Inside the Tsuchimoto Academy, All-Boys High School, where dead bodies of male students and male teachers, who are totally perverts and sexual predators preying on the female teachers without remorse, are now lying on the hallway and the corridor. A high school student name Tatsuya Kurose (2), who was badly injured and blood flows on his face as he crawls away from that monster that kills his pervy comrades and he still hear their dying scream as he still keeps crawling, but he stomped by huge pressure on his back as he started to sweat in fear and slowly turns around, but it was too late for him to scream as he got clawed to death as blood on the floor.

Inside the principal's office, where a 54-year old man Keizou Hirukawa (3), the man in charge of all-boys school, he tried to call his partner-in-crime the phone in desperate of help that the reptilian monster kills the students and teachers, except the female teachers who were the victims of their sexual abuse. He was sweating as he was waiting his partner to answer the call.

"Come on, come on, pick up the FUCKING PHONE! ! !" Then the door blasted in explosion, *BOOM!* which made the pervy principal duck down on the desk and for a matter of minute.

He rose up from his desk, as he look at the door open and the figure came inside that made Keizou widen his eyes in terror that reptilian monster standing there is none other Alycia Draconys, who was once a mortal human and now she's now a HellDragon, she's working both the Royal House of Morningstar and IMP, it wasn't really hard for her living on Hell since she has the blessing of the Red Dragon and Satan. She made friends at Hazbin Hotel: Princess Charlotte "Charlie" Morningstar, Vaggie, Alastor, Nifty, Husk, Angel Dust, and Fat Nuggets; and made friends with Immediate Murder Professionals: Blitzo with a silent O, Moxxie, Millie, and Loona, since they are a good bunch of assassins.

She made few powerful allies on Hell: King Lucifer Morningstar, Queen Lilith Morningstar, Prince Stolas of Ars Goetia, Rose, Carmilla Carmine, Zestial, and Velvette since she had a huge crush on Alycia.

Right now, she had an important mission assigned by the King of Hell himself which she accepts it since its part of her job after all by hunting down the prey. She now stands in front of the pervy principal, who was now whimpering of fear and he urinate his pants which made the dragoness disgusts as she raises Hellbringer and points at Keizou's head.

"Lucifer sends his regards."

"Wai-" *Bang!* Bullet made of Hell pierce through his head, and his body laid down on the floor.

"Enjoy your new life in Hell." She was about to leave, but she hears the voice on the phone.

-"Keizou, you called? Oy, this better be important! I have serious business here! Oy, are you there! ANSWER ME!"-

Alycia picks up the phone, and she answers him. "It is unfortunate that your partner is unavailable."

-"Who is this?"-

"Me?" She her gun with hell bullets and her reply. "I'm a Creature of Hell, that comes to Earth and punish the wicked. And you, bastard, are part of my hit list." She's cocking her gun.
