In a space between universes, an obsidian-scaled dragon the size of a few planets combined was sleeping. This was one of the most powerful dragons second only to the mother of all dragons. This was another companion of an incarnation of the Strongest, Tanith.
She was dreaming her never-ending dream of the days she adventures with Edge Regius and Rei Kuraki. Those days of fighting alongside her companions were the best of times. Back then Tanith thought those days would continue forever, but after Rei's death, their contract could no longer be felt.
She could not understand it at the time, as the Strongest Mortal Soul wasn't he bound to reincarnate endlessly, so surely he must exist somewhere. In the beginning, Tanith alongside Tsukiyomi traveled through different universes trying to find the reincarnated Edge, but no matter how hard they tried they could not find him, eventually, Tsukiyomi stopped her journey with Tanith.
"Sorry Tanith, unlike you I can't continue for too long without my contractor. So you need to continue this journey on your own for now."
"It's really weird if you suddenly speak like that, it's like we'll never see each other again." Tsukiyomi smiled slightly as she closed her eyes before responding.
"Kukuku, well then Black Dragon Tanith, I guess this is goodbye for now. I will return to the place where Edge and I first met. If you meet first be sure to bring him to that place."
"Don't order me around you little Ethereal..."
"See you fat lizard."
The two looked at each other seemingly about to start a battle, but after glaring at each other for a few seconds the two started giggling.
"Take care, Tanith."
"Sleep well, Tsukiyomi."
The two then parted ways, and after that Tanith continued on her journey to find the new reincarnation of the Strongest Mortal Soul. Tanith visited numerous universes, in some she was the savior and in others, she was the destroyer. Still, to Tanith all of those things were just fleeting scenes in her search for the current Edge.
At the start of her journey, Tanith would get excited visiting a new place thinking this time she would find the current reincarnation of the Strongest Mortal Soul, but as time went on that enthusiasm began to fade and was replaced by a growing dejection.
Even for a dragon tens of thousands of years was a long time. At some point, Tanith gave up and hid in a space between the universes, between the upper and lower planes. In that space she was all alone, where she sleeps dreaming of the days long past, of the adventures with her beloved companions. She even remembers the last time she spoke to Rei Kuraki.
It was the eve of battle against the avatar of the ORIGIN, many people had fled the part of the galaxy where they were going to do battle. Rei spoke to every single companion of his one-on-one, and then it was Tanith's turn.
"Tomorrow will most likely be our final battle. So tell me how are you feeling Tanith?"
"Heh, Rei Kuraki there's no need to bother worrying about my mental state. As a mighty black dragon I do not fear the Gods nor am I willing to bow down to a maddened creator. I will fight with all my might that you can be assured of." Hearing Tanith's reply Rei shook his head.
"I already know that, and that's not why I'm asking what you're feeling now Tanith... I know that you Tsukiyomi and a few others only follow me because, in my past lives, I was a lover, master, and parent to you guys. Still, I want you to know that it is true that I was once Edge Regius, but Rei Kuraki is a different person. Even knowing that will you still follow me to certain doom?"
"Heh, HAHAHA! Is that all you wanted to ask? I already understood that no matter how similar you two are, and even though he was your past life, you are not Edge Regius. Though it is true that the only reason I followed you, in the beginning, is because you were his reincarnation and the contract we share, but now I follow you because Rei Kuraki is someone I trust."
"Is that so?... Hey Tanith, after the battle what do you plan on doing?"
"I plan to continue following you. Staying by the side of the Strongest Mortal Soul no matter the incarnation is always bound to be fun and exciting."
"I see... Alright, it's decided then after the battle all of us should go on another grand adventure how about going to find the mother of all dragons? Yeah, then we can go visit the birthplace of the Ethereals."
Rei continued to speak of the grand adventure they would have after the battle, and Tanith continued to listen with a smile on her face. Unfortunately, all those plans will never come to fruition, as the next battle will be where Rei Kuraki would take his final breath. The grand adventure they planned to go on could only happen in their dreams.
...
Tanith who was in her deep sleep continued to dream, of what used to be and what could've been. The space she was in suddenly shook and she felt a familiar presence. The eyes that had been closed for thousands of years finally opened and a roar that shook the void came out of her.
'I can feel it he's finally appeared! Where is it?! I need to meet him right now!' Tanith quickly tried to sense the location of the new reincarnation of the Strongest Mortal Soul through their contract.
'The upper planes!' Once she found the location Tanith spread her wings and broke the barrier between universes and flew at full speed.
'I wonder what the new reincarnation is like. Obviously, he's going to be someone who loves battle. I wonder if there are many women beside him like before. Did Tsukiyomi already meet up with him or am I going to be the first one? I wonder if he has memories of his past lives, like Rei Kuraki. I really want to meet him faster!'
Tanith felt a long-lost emotion, she felt excited. Tanith appeared in the upper realm where the Gods and the truly strong humans live in. She was able to sense the new reincarnation of the Strongest Mortal Soul, but for some reason, his aura that suddenly exploded in strength was now being drained at a terrifying pace.
'He's in the middle of a battle which I already expected but, he's actually losing? Who's the opponent?'
Tanith finally sensed the aura of divinity that she hated so much, it was an Old God that was facing the current reincarnation of the Strongest Mortal Soul. Tanith teleported into the area near the battle and sealed the area so that the Old God won't be able to escape.
'Damn it! I just found you, I won't allow a stinking God to take you away from me again!'
Tanith roared at the Old God who seem to be taking away the unconscious reincarnation of the Strongest Mortal Soul. The Old God Gwydion changed back to its original size and was about to confront the incoming Tanith.
