Neo D. Fowler/Plot

## Underworld Arc

#### Introduction

Neo is introduced to the story when Rey returns to the demon’s castle after being reunited with Rouge whom he had believed to have been dead for 15 years. He is met by Neo playing his piano which seemed to brighten his mood up a little. Neo sees that the imp was upset and asked him what the matter was but Rey tells him that it's nothing. After some prying, Rey finally cracks and informs Neo of Rouge’s return. Neo beams at the news, telling him that that’s great that his sister is alive which causes Rey to become hysterical. The imp questions him if all that bloodshed was for naught before quieting down and demon how Rouge was a complete shell of her former self. Neo comforts Rey until the imp had fallen asleep in his arms and carries him to his room. After tucking him into his bed, Neo’s caring façade fades away as he is filled with the desire to find Rouge and make her his bride.

#### Rouge’s Abduction

Neo makes another appearance 2 chapters later when he knocks Rouge out using his amulet illusion ability and assaults her in his bed as she is still paralyzed.

The next morning Neo invites Rouge for tea which she attends in her new get-up. Neo asks if she fancies the dress he had made for her which she just ignores and takes her seat next to her brother. Neo summons a crystal ball showcasing Kazuki and the rest which causes Rouge to shoot up from her seat. Neo mentions how Rey had told him that she was looking for someone and asks Rouge if she had any relations to Kazuki, pointing out their striking resemblance. Rouge bites back a response as she lowers herself back into her seat and moved her teacup closer to herself.

Kazuki and the others suddenly disappear into thin air, causing Rouge to question whether or not the group somehow made it out of the Underworld without the use of the grimoire. This sends Rouge’s mind into a frenzy which Neo notices and decides to cut their little tea party short. He calls for Rey to escort her back to her room which Rey obeys and the imp gets up. The two walked out of the room hand in hand, leaving the demon alone to give the crystal another brief glance before making it disappear at the snap of his fingers and taking his leave as well.

Rouge is seen a while later in bed, gazing up at the crystal ball. Despair hits when she sees Kazuki reappear in the Underworld from the Forever-still Space, confirming that the others hadn't left at all. Neo sighs as he enters his room and sits down next to the demoness. He verbalizes his desire to learn more about her but Rouge ignores his request. He sighed once more as he snapped his fingers, causing the crystal to disappear. Neo gets on top on Rouge and with a wild grin, tells her that she’s only allowed to stop talking *after* he achieves his dream. Rouge becomes confused from his usage of the word “dream” but she keeps her lips sealed.

A knock on the door makes Neo curse under his breath and asked who it was. Akuji answers from behind the door, telling him that he brought some lasses over and proposes that they have some fun together. Annoyed, Neo tells the drunken demon that he’s not in the mood right now which causes Akuji to teasingly ask if Neo already had a woman in his quarters. Neo sternly orders at Akuji to leave and the latter does so with the two women he brought with. However, the lime-haired demon's mood is already spoiled and he turns over to sleep which Rouge eventually does as well.

#### Axel vs Rey Aftermath

Neo intervenes at the end of Rey and Axel’s fight, summoning the former back to the castle where the imp is punished for acting on his own accord. Taking off his glove, Neo slugs the imp hard in the mouth, causing Rouge to tackle the demon from the bed with the force of it knocking him to the ground. As she struggles to keep him pinned to the ground, Rouge yells at Rey to run away but he doesn't move and Neo pulls her off with all his strength. The demoness is knocked out when she hits the bedpost and Neo gets up to look at her unconscious body before shouting at Rey to do what Rouge said and get out. Rey didn’t need to be told twice by his master and runs out of the room, slamming the door shut behind him.

#### The Reveal of Nadia's Fate

Alone in the castle, Rouge takes by going through Neo’s things in order to uncover the demon’s agenda. In the middle of moving clothes around in his large closet, Rouge makes the horrifying discovery of Nadia Edward's corpse. Hearing Rouge's screams, Neo runs into the room in a heartbeat and croons when he sees what Rouge had discovered. Rouge’s asks him if he had murdered her which the demon hums delightfully at as his hand caresses Nadia’s cheek. Suddenly his grip tightens and his nails dug into her incorrupt flesh as he started remembering things from his past which he explains in detail to a horrified Rouge. For awhile, Neo laughs before becoming dead serious. As he places the veil back over Nadia’s face and tucks her neatly back into the closet, he tells Rouge that when he becomes god, she’ll be the next to wear this dress. Neo then exits the room, leaving Rouge alone with this horrible newfound information heavy on her psyche. From behind the door, Neo revels in her cries until he is approached by a grinning Akuji.

Teasingly, Akuji asks him if it’s still the same girl he had over before, further inquiring if he had finally fallen for someone. Neo just looks away with a coy smile on his face which Akuji took as a yes. Akuji then proceeds to joke about how heartbroken Rey must be and asks Neo if he could see her while pressing his ear to the door. That is when Akuji hears Rouge’s cries and is shocked, looking at Neo who asks him if he’s on his side and tells him that he will get to spend all the time he wants with the goddess just beyond that door if he continues to be on his side. Just before leaving, Neo takes in Rouge’s beautiful cries once more and exhales, making sure to bar the door using his mage-craft so Akuji couldn't enter.

#### Blanc vs Akuji

With Rouge distracted by the crystal ball displaying the battle between Blanc and Akuji, Neo moves in to plant a small kiss on her lips. Blessed by the sight of her shocked reaction, Neo laughs hard and teases if she’s surprised because that was her first kiss or if she’s disappointed that he didn’t use tongue.

In the end of the fight that saw the deaths of both opponents, Rouge's brain shuts down permanently. Neo leaves Rouge alone to go to Rey's room where he asks the imp if he wanted to go into town with him. Completely flustered, Rey is unable to respond but Neo takes his answer as a yes. Rey was convinced that this was a date which was made even more evident when Neo brings him to a love hotel. However, Neo had other plans and used this opportunity to kill Rey. Holding his arm out to the side, Neo summons his Ephemeral Platinum Saber as Rey becomes completely limp. He praises the imp for giving up so easily and tells him to let his pathetic life be taken by his saber's light.

Awhile later, Lita confronts to Neo confront Neo about the disappearances of Akuji and Rey. As Neo was talking to her, Lita's eyes locked on Rouge's body in the background. Panicked, Lita pushes him away and runs over to the bed where she saw Rouge laying there unresponsive with her eyes wide open. She checks the pale demoness’s wrist for a pulse but after finding none, she closes Rouge's eyes out of respect. Lita turns back to Neo and demands to know what the meaning of this is. Neo says nothing as he summons his saber, causing Lita to cry out in seething anger. Lita manages to land a few hits on Neo with her lightning kick and appears to have the upper hard until the demon remembers his dream, replenishing his fighting spirit. Neo delivers a diagonal slice to her chest, throwing Lita to the floor right beside the bed. After having to listen to Neo make a few remarks about how much of a shame it was that he couldn't make her his woman, Lita snaps and told him to go die. He clicks his tongue at the dark-skinned demoness’s curtness and shoots her a few more demeaning remarks which she responds by saying that whatever his goal is, he'll never achieve it because Kazuki and his friends will stop him. Sick of hearing her talk, Neo raises his saber to put her out of her misery but stops when Oralee walks in on them. Lita takes off her bloodied cloak and throws it at Oralee, the cloak blanketing the younger's head. Relief washes over Lita as Oralee was transported far, far away. She closes her eyes and leans back as she was swiftly decapitated by Neo.

#### The End

Neo uses his strong presence to lure Kazuki and Take-down Squad to an abandoned town. Even though the demon was obscured by a heavy fog, his immense bloodlust that exuded from him shook the Overworld-born trio to the core. Neo's form is finally revealed which causes Kazuki to be confused on why the demon came alone. Neo confesses that he killed Rey and Lita which outrages Kazuki. Kazuki demands to know why he would kill his own people and if he killed Oralee too. Neo lies and says he did kill her, adding that he "had fun" with her body afterward. Kazuki strikes him with his onyx blade but Neo blocks it with his own platinum blade, sending sparks of light and darkness into the air as the two weapons continued to make friction from one another. The human threatens over and over again that he'll kill him which was just the kind of reaction Neo was hoping for. The demon inquires what chance does Kazuki have in beating him, revealing that he wields the same saber that massacred all seven of Hades's archdemons and their families. He then exposes how he learned the truth of Kazuki's existence through Rouge herself, calling the redhead a rock that mistakenly given sentience. Kazuki screams at him to shut up as he charges at Neo once more and as expected, the demon blocks it with his weapon. However what Kazuki didn't expect was both of his tonfa blades shattering to pieces.

An grand idea then sparks in Neo's mind and he screams out to Kazuki that this is the end. Sherbet yells at Kazuki to look out which succeeds in snapping him out of his shock and miraculously the shattered remains of his tonfa blades form a shield, protecting him from the blow that would’ve ended his life.

However, this was all an illusion made by Nep and it revealed that Kazuki was stabbed in the heart. Neo fuses with his saber and he awakens as a god, appearing more angelic than demonic. With despair and rage fueling them, Sherbet and Axel charge at Neo but they were both killed with a single head tap that destroyed their brains.

As Kazuki's body suddenly combusts into black flames, Neo rises in the blackened sky with multiple versions of his **Ephemeral Platinum Saber** encircling behind him. The flames covering Kazuki subside, revealing the human in his Cerberus form.

Ndo is defeated by Kazuki's newly acquired Hades **Raging Blood Burst** which sends him to his own Forever-still Space. Neo discovers himself lying on the floor of the Viscera Purger's dining room when Nadia's zombie enters and pins him to his spot with her knives. Nadia crawls on top of him and sunk her hand into his gut, eviscerating him slowly by hand. Neo wasn't fazed by his mother shoving his guts into her mouth. The only thing that made his fate an actual living hell was the heads of Cerberus judging him from the walls.
