Kyujigokuten-no

Kyujigokuten-no is a Demonic Kaijin Hero that first appeared in the book The Autistic Hero 2: Worlds Clashing. It is a Demonic looking kaiju of destruction that just so happens to be the first demon kaiju shifting Son of Lucifer in and Lilith who at first looked like an innocent cutie demon child but then due to his alignment being auto evil by the humans he couldn't be trusted to play on the outside world. Kyujigokuten-no was isolated to Avernus which was his playground for years as he grew a new form. Kyujigokuten-no never appeared in any mention in the bibles and didn't even appear in the Codex Gigas meaning the only people who know him are the demons in hell at the time. He however does have a mutual respect for humanity and doesn't touch sinners as those are for his father to deal with.

## History

Kyujigokuten-no Is Lucifer and Lilith's first ever son in their Exile in Avernus and at first was raised as an average child and looked like a little Tiefling but Kyujigokuten-no ended up becoming very protagonistic after he saw how evil some of the sinner humans really were. He began to discover that the River Styx where the other types of demons were sealed in turns out to find its way to enter the other layers of the nine hells. After his father began going to work on training to be stronger than the angels that keep them there. He began to ask some of his father's many other demons on how to get stronger. If Haruo Ikamoto the souling hadn't destroyed the archangel keeping the barrier around Hell up then it would have been Kyujigokuten-no who would have defeated them. The son trained with every single demon he could find and eventually both his normal demon boy form and his Demon kaiju form got strong enough to rival even Gabriel himself. However his curiosity got him to reading Pre-sumarian ruins and discovering the existence of aliens. He knew there was something stronger out there in space so he broke the barriers getting into the lower level of Dis and sees that there's another hellish ecosystem beneath them. These demons gave the boy a better challenge and he even took on Styx Dragons to better challenge himself. After centuries of testing himself he eventually decided the best way to make up for his absent behavior was to climb back to Avernus and spend time with his father and mother. in 4050 the boy was trying so convince his father to let him go help and fight the incoming Angel Invasion in The Autistic Hero but Lucifer knowing that this was the full Armageddon and that angels would gang up on him. However Lucifer did consider the fact that his son needed to know the feeling of destroying a Blind Idiot Angel so during the main climactic fight against Gabriel, Lucifer brought a Seraphim angel back to Avernus to a rather sulky Kyujigokuten-no. Of course the boy was overjoyed and ended the seraphim with a single stroke of the Nine Hells Doomblade and is praised for his amount of training he put into it. He then went on in the second book to interact with and this time was the person who Mentored the Treacherous Nine in return for creating the Nine Hells Doomblade for the incoming emperor of the nine hells. It is after he learns that they made it for him that he realizes his father Lucifer planned for him to be the new emperor of the nine hells since he was going to the Overworld to patrol. In the events before Kyujigokuten-no encounters Xenith Stephenson and finds out the Treacherous Nine were corrupted, he spends his time in the Nessus layer contemplating what else there was to train against. It isn't until He gets attacked by a possessed Ice Devil that he realizes the true issue at hand. Of course he defeats the Ice devil after it attempts to run away from him only to be decapitated by an unexpected Xenith who crushes its Icy Chitinous shell with Zygodactyl Claws. They have an interaction and then both tag team against the Treacherous Ninth to release him from his mind slavery. He and Xenith become close friends and he gives Xenith his contact info which is just a pentagram with a grinning face in the center which is used to summon him in very dire battles.

## Appearance

#### Demon Boy:

In his Demon boy form he looks identical to a Dungeons and Dragons Tiefling as he has the light red skin and Demon pointy tail. He has his father's black hair and his inverted cross eyes. He also has ram horns and dark angel wings and halo.

#### Demon Kaiju Form:

In his enraged Kaiju form, The boy transforms into a hulking monstrosity that is Hellbent on protecting the Nine Hells from evil and angels. This kaiju was primarily green and black and covered in cracked, osteodermal armor on its abdomen, shoulders and head, with a tail for stability that can split into 3 pronged tails that inflict an infernal wound on piercing impact. The abdominal parts of the armor are segmented like vertebrate before converging into a prominent spine on its chest. Patches of Green flame also reside on the pectoral regions of his chest, and veins of it run throughout the armor and the body. It has strong forelimbs. The set possesses large palms with Ten Zygodactyl claws, The armor of its head extends as three inward-curling horns on the top and two on the bottom akin to tusks, while its face is flat with a muscle fiber-like texture, two blue eyes, and exposed teeth. The creature also has ram horns above the first set of inward curling horns which are hollow and can shoot energy blasts. It seems to always drool Demon Fluid and its also equipped with Dragonfly-like wings which are very much made of some kind of light alloy that also is able to reflect Angelic and Mortal weapons such as world war 2 tank rounds. These are segmented into 3 folds which at the tip of the wings is another set of claws which these more resemble the Talons of Birds of prey such as hawks and these give the wings more function being able to grab airborne enemies before they can attack from above. The creature also has ten tongues which are all wrapped around each other in a kinked nozzle formation and they glow a hellish green before firing beam attacks. Its roar sounds like a mix of many demonic roars but the most haunting noise it can make is the sound of a child howling like a Wendigo at night. The creature's size alters a lot based off what it is currently fighting but its average height is 185.20 meters tall, a length of 370 meters long on average and hosting a wingspan of around 322.42 meters.
