Noticing how stressed Bronya seemed, Cerberus, in instinct, gently pressed his palm on the woman's head. Rough, calloused, and scarred hands gently patted the gray hair of the look-alike of his dear friend. 

"Relax," Cerberus said as he looked at his companions. For her part, Bronya froze as she felt the hand on top of her head. 

'T-this is not appropriate!' Bronya roared in her mind yet she leaned to his hand gently.

"Woah... he's taming her," March said towards Stelle who looked at the scene intensely. Dan Heng merely shook his head as he prepared himself.

Removing his hand, Cerberus untucked his gray shirt, looking more like a delinquent as he cracked his neck.

"Come on, we don't want to keep Seele waiting," Cerberus said as he pulled out a stick of cigar from his pocket and bit on it before snapping his fingers, causing it to light up. 'I just hope she doesn't have a...' "Oh? Interesting," 

"What is it Cerberus?" March asked, immediately focusing on the dark-haired male. 

"Several mines are... 'corrupted,'" Cerberus said as he took a drag from his cigar, inhaling the smoke before exhaling it. "The mine we're going in has a lot of people in it,"

"Hmm???" Noticing how the pink-haired girl did not seem to believe him, Cerberus reached in. "Yowch!" the young man pinched March's nose gently as he closed his eyes. 'I see, so that's why,' The young man thought as a mental map of the entire underworld appeared in his mind. 

Numerous places. no, mines were sealed off and were... 'corrupted' compared to others. 

"Are you, alright?" Soft golden eyes met with amber-misted Obsidian. 

"I'm fine," Cerberus said, letting go of March's nose. As they approached Seele, the young man broke off from the group and eyed a cart filled with ores. 

Keeping himself silent, Cerberus followed the group and raised his brow at the sheer sass that flowed from Seele. 

Following the group, Cerberus saw the giant ore vein. 

"Impressive, right?" Seele asked, looking at the vein while Cerberus...

"I guess," Cerberus said, his obsidian eyes boredly looking at the construct in sheer... disappointment. 

Hearing Bronya's comment about how robots should always follow humans. 

"Well, you'd be pretty surprised," The young man said, remembering a memory of when he and ***** somehow managed to accidentally cause a minor 'Terminator' scenario.

As the group walked into the mine, Cerberus calmly let Seele, Bronya, and the others take care of the threats. After all, it was their job,

Noticing something about the group in front of them, Cerberus let out a sigh as he cracked his knuckles.

"You shameless scoundrels..." Seele gritted out as she glared at them and that was enough time.

Despite no longer having his Gnosis, the several millennia of skills that he had learned and used allowed him to easily dispatch the vagrants. Stopping in front of one, the young man delivered several strikes to the body and a palm strike to the jaw before throwing him on the other with enough force to knock them both out without wasting any time, the young man grabbed the last vagrant and threw him over his shoulder and at the other two.

The young man noticed how the one on the bottom slowly woke up but it was to no avail as he weakly slammed his shoe on the vagrant's temple, knocking him out. Saying nothing, the young man took his cigarette out of his mouth and ignored the way how it dissolved to dust. 

"You're welcome," the young man said as he picked up a polearm before chucking it away as he went back to the trailblazers, ignoring the look he got from the group.

Noticing how both Seele and Bronya might get into another argument, he did not really care why, the young man leaned on the wall, enjoying the feeling of the earth all around. 'Can't believe it's almost been a decade since I sealed myself away,' the young man thought as he followed the group once more, nodding at Dan Heng. 

Following the group, the young man stayed out of the fighting, letting the others take the monsters as he focused on the giant ore deposit. 

'Compared to what Morax can do,' Cerberus raised his hand and mercilessly crushed the head of a machine in his hand. 'This is quite pathetic,'

Eyeing the grizzly-like robot, the young man sighed as he decided to throw the others a bone. Sending a pulse, the young man changed and weakened the ground under the monster, causing it to get trapped and become easy pickings for the others. 

Staying quiet during the negotiations of the group, the young man waited until they were done. He was not idle as he send numerous pulses, refining the mental map that he had of the entire mine, locating any possible... 'income' as well as locating numerous ore veins. 

Making sure to keep an eye on Bronya, the young man waited for her to get finished her talk. 

"So, how did it go?" The young man asked, leaning on a wall as he looked at the... more mature alternate of his friend. 

"It is informative," Bronya said as she looked at the taller male in black. 

"Very well," The young man said as the two walked with the young man wincing inwardly. 'No, she is not the same Bronya...' The young man thought as the young man siphoned the energy found on the earth to heal the damage in his body. 

"How did you manage to sneak into Belobog?" Bronya asked while the young man hummed. 

"It was quite easy, I just had to time things right after observing how people acted and Not interacting with many people helped," Cerberus said. 'Well, not for everyone. After all, I had to train and create a lot of techniques, luckily I created them and I can use them without a vision or Gnosis,' 

"That's not normal,' Bronya said, her gray eyes narrowing n his form. 

"Like your growing fondness or respect for Seele?" Cerberus asked, closing one eye as he looked at her. Obsidian orbs watched as a pair of gray widened slightly. 'Interesting,' 

"Bronya-onee-chan!"

"Ah, Seele. I want you to meet ***," 

"Ah, you must be Rex! Bronya-Onee-chan told me a lot about you," 

Obsidian eyes watched fondly as the bunny and the butterfly looked so in love with each other. 

See, even back then, you never had a place by their side, coward.

ignoring the dark thoughts the young man leaned on the wall, once the talk he had with Bronya was finished. 

Closing his eyes and entering a meditative state while leaning on the wall with his arms crossed, the young man sent pulse after pulse in the same rhythm as his heartbeat. 

"You didn't sleep?" 

"No, I've been meditating all this time. Never really need to sleep since I perfected my meditation," Cerberus said as he opened an eye to look at Stelle. 

"That's not healthy," Stelle said as she looked at Cerberus. 

"Been sleeping for too long," Cerberus said as he looked her in the eye, "Why not talk with Bronya?" 

"You're casual with her," Stelle said, golden eyes looking at him. "You're open with both her and Seele despite knowing them shorter than you know us,"

"I have my reasons," the young man said as he kept his eyes on her. 

"Very well," 

Going back to his trance, the young man noticed how Seele, Bronya, and Stelle exited the town. 

It took him a while to follow Seele and the others. Making sure they were safe and inside the town, the young man gazed at the Fragmentum monsters. 

"Honestly, this is such a drag," Cerberus said.

A man with H/C hair reached for the chess piece he once held. The soft glow of the Gnosis allowed Cerberus to see the man, Morax's Real successor. 

"I hope you lead a better life and legacy than I do. Your potential and compatibility with the Geo Gnosis far exceeds mine and you will grow stronger than I ever will with the Geo Gnosis. After all, I am more compatible with Anemo." 

Countless monsters jumped at him, intent on ending his life. 

"I will have an order," Cerberus said with a smirk.

The Fragmentum monsters suddenly crashed to the ground, disappearing as their bodies were crushed under an intense amount of pressure with only the sight of cold, unfeeling, and impartial obsidian orbs of the one that was formerly known as the joyful lord of the earth.

Omake: if Archon Reborn's Y/N went on a date with Fu Hua 

"..." 

"Cerberus?" 

"This feels strange, Y/N?" 

"Why? Wait, were you dating your universe's Fu Hua?" Y/N asked through the mental connection the two shared. 

"No, Y/n. Fu Hua is my ancestor," Cerberus said as Y/N looked at him. 

"NANI THE FUCK?!" 

"Well, my ancestor never survived and my family does not exist in this universe, go have a fun date or something," 

"Wait! Cerberus! Cerberus... CERBERUS!" 

===============================

Omake 2: If Archon Reborn's Y/N ended up with Li sushang

"Okay, this is confusing," 

"What is it this time?" 

"I'm confused if I should call you my nephew-in-law, brother-in-law, or something." 

"Don't tell me..." 

"Well, Li Sushang is one of my gene donor's biological daughter and I am a partial clone and descendant of her father through his brother's side," 

"What's wrong with your family?!"

Canon extra: 

Bronya Zaychi smiled as she finally finished her most important project, one that she created from scratch. A video game about the man that she called her best friend.  

Taking a look at her desk, Bronya smiled as she saw the photo of her and Rex during their time at St. Freya Academy. Bronya sat on his lap, holding an amber-colored Homu doll while she let out a soft yet sincere look in her eyes despite her emotionless facade. 

-------------------

Canon extra 2:

"Daddy!" 

Cerberus turned around. Obsidian eyes widened as he spotted a shorter female version of his oldest brother. Gently, the young man picked her up. 

"Holy... s... I mean sweets." 

The girl giggled. 

"Wait you're not daddy!" 

"Of course, not. I'm Cerberus,"

"C-Cebersus?" 

"No, Cer-be-rus," 

"Cerberus?" 

"Good girl," 

"I'm Rilliane [REDACTED]-Crozzo," 'Holy shit, Rein had a kid with her?!'
