[Middle School]

It was one sunny day on a football field when he first met Hiruma. They had a duel in which he had managed to scratch his uniform, and he succesfully put a collar on him. It was a draw. That day he considered Hiruma as his equal, his comrade. He gets food and shelter by following the quarterbacks orders, which was fun if you see those scared faces when he chased those cowards around.

At first there were the three of them. The damn fatty as per Hiruma also called "Kurita", and the fucking old man which others call "Musashi". Watching the three of them made Cerberus realized that having a comrade can be quite fun. So Cerberus added them to his Comrade's List. Though Kurita needs to be whipped into shape, he does not hesitate to bite him hard if Hiruma tells him too. As for Musashi, it took one staring contest for Cerberus to consider him okay, he does not avert eyes, maybe just a little below Hiruma though.

[High School]

"Christmas Bowl", in the years he had been with the trio it seems like that word was the glue that was sticking them together. That is, until Musashi stopped coming. It was after he abandoned the field before a kick, he'd been there. Hiruma kicked the football equipment when the kicker left and he immediately knew, something is wrong. The air of sadness that has been around gives it away. Being a dog has its disadvantages, don't get him wrong he is smart, he just needs further explanation.

It was another late night escapade at the clubhouse when he got to talk to Hiruma about it. He might be a dog but he knew if something is important, you won't leave it behind. So when he saw the kick tee discarded on the field during the Ojo-Deimon game, he picked it up and kept it.

He strutted his way to a focused Hiruma who was typing away in his laptop.

'Growl' he let his presence known, prompting the quarterback to look up. He put the kick tee from his mouth in front of him and stared at Hiruma, which was grinning like a madman now. Cerberus plopped down next to him, but not close, conveying an air of indifference around him.

"Kekekeke! He'll be back damned mutt. Just wait for it." Hiruma cackled as he acquired the kick tee. Something about his eyes tells Cerberus that he is so sure.

'Growl' He better be. Cerberus provided as he munched on the beef jerky Hiruma that produced out of thin air.

They were a duo for a long time when a pipsqueak came, and seeing Hiruma very enthusiastic about it he thought maybe this one can make it to his comrade's list too. And he's fast, he could use him for his leg workout, Cerberus thought.

Then after pipsqueak came the girl, she had an air of protectiveness around her. Especially around the pipsqueak. He remembers her actually, it was one Saturday during their first year when Hiruma planned to bug the whole Deimon with spy cameras when the girl happened to stop by near the clubhouse and saw him. Normally, a girl would run away seeing such a vicious(ugly) dog like him. Instead, she looked at the clubhouse behind Cerberus and smiled at him. She SMILED! Cerberus was a freaked out a little.

"Must be hard ne? With only just Hiruma-kun, Kurita-kun and Musashi-kun in the football team." she mused fondly. "But they won't give up right?" she smiled as if talking to the dog.

'Damn right' Cerberus growled in approval.

She shifted the box she was carrying when the smell reached Cerberus nose, he eyed the box suspiciously. Mamori noticed and contemplated for a while, she opened the box of Kariya creampuffs and showed it to Cerberus, "Would you like some?"

Cerberus wagged his tail, the sweet smell got him excited.

Mamori hesitated but took a puff and lowered her hand to the mutt's mouth. She didn't think of throwing it on him because he might think she is a bad guy. Cerberus very gently stalked and ate the puff as she settled it to the ground. He did not lashed out and stole the box from her, simply because she understands his 'Comrade's List' foolish dream.

Cerberus was taken a back when he felt a hand patting his head, "Such a good boy."

Good boy... Good boy.. (A/N: please imagine this as echoing sounds lol)

He beamed, being praised like that is something that Hiruma never does. And the pat on the head is a whole new world to him, and it felt oddly good.

"Well then, I will see you around!" Mamori got up from patting him. Cerberus made a mental note to chase away those boys she looked uncomfortable chasing her around.

"...What the fuck are you eating you Damned Mutt?"

Cerberus spared a glanced at Hiruma, grabbed his left over puff and brought to his kennel. That girl just squeezed herself into his Comrade's List. Maybe just a little below Kurita. After all, she said he is a good boy.

[Deimon vs. Taiyou]

The sun was very hot but the game to determine the representative to play with the NASA Aliens. It is the second half and Deimon is catching up.

Cerberus was distracted from watching the game when water was placed in front of him. Mamori smiled at him and left him be, he growled his thanks when she was out of reach.

It is not bad if there is someone like her looking after him, he actually kind of enjoys it. Cerberus stared back at the field and laid eyes on Hiruma. There should be someone looking out for that guy too, well he is his equal but still. He glanced at the manager and caught her staring at Hiruma too, well maybe, just maybe...

[Death March]

Cerberus walked around the Devilbat Go to take a dump after dinner. He noticed the manager and the quarterback at the back of the truck. With Hiruma bouncing his feet so Mamori will have a hard time bandaging him.

"Mou Hiruma-kun stop moving around!"

Hiruma acted like he did not hear anything, and continued to bounce his feet. "There its done, mou! And don't remove it!" Mamori warned the quarterback before stalking off.

Hiruma glared murder at his bandaged knee. Cerberus took this oppurtunity to strut his way to him.

'She got you there.' Cerberus growled looking at his knee. None of the brats, not even Kurita noticed it.

Hiruma looked at the dog like it has grown two heads and raised a brow. He continued tapping away on his laptop but Cerberus can see a crack to the walls he built around himself. And a certain manager was the culprit.

Oh wait, he remembered he had to dump.

[Deimon Vs. Bando]

"Kobayakawa Sena!"

The crowd roared as the identity of Deimon's eyeshield21 was revealed. Despite the fuss, Cerberus can only focus to the teary eyed manager in the hallway. To say that the mutt is worried is an understatement.

Mamori had joined because she thought the work as a secretary was too much for Sena to handle and to protect Sena from Hiruma. Now that Sena does not need her protection will she leave the team?

Who will give him tasty food now? Sure Hiruma gives him food but Mamori'd cooking was by far the best he had.

Who will bathe him now? Hiruma can do the task but Mamori does better. She even blow dries his fur after!

And lastly, who will be there to watch over Hiruma? He noticed this, the little exchanges they had. The way Hiruma was behaving 'a little' because she is reprimanding him on the school grounds. And the way she does not intervene with his spartan ways in training the team. These two understand each other.

Cerberus walked up to Hiruma and barked, despite the loud cheering of the crowd for Sena, Hiruma looked at him and Cerberus nodded to the hallway. Where Mamori has seated herself in a bench and crying silently.

"Tch. Getting attached aren't you, you fucking dog?"

'Just do something about it!' Cerberus growled impatiently.

"Keh, you think I think I haven't thought about? Just fucking wait for it." he cackled.

"Eh mamo-nee?" Suzuna was about to skate.

"Leave her alone."

"Eh?"

"She is not that type of woman. She'll be out in a moment."

Cerberus had the urge to roll his eyes if he can, attached eh? Look who's talking.

"And lastly, the manager... Anezaki Mamori!" the speakers boomed and just like that. Mamori jolted out of crying and ran out of the field.

Cerberus turned to Hiruma and growled a 'Good job'.

"...and is expert in high speed snack eating!"

"Mou! Hiruma-kun!"

"Kekekekekekeke!"

-oOo-

After the victory party, when everyone had gone home already. Mamori was left in the clubhouse to clean the mess. After cleaning she remembered the things she had said to eyeshield21, to Sena. She slumped down to the floor breaking down in tears.

Cerberus would walk in on her sitting on the floor, with her face buried in her knees. She was crying.

"I was... selfish. Very very selfish." She whispered.

'Growl' Mamori was a little startled when she raised her face only to see the evil mutt looking at her.

"Ne Cerberus? I turned a blind eye on Sena this whole time didn't I?" she hicupped laughing a little.

"I think this will be my last day in the team ne? Sena does not need me to protect him anymore. I can always cheer him from the crowd." she added bittersweetly. She looks like she was convincing herself.

'Oh no! This can't be! You can't leave the team. I need you! Hiruma needs you! Everyone needs you!' alarms was setting of Cerberus head.

He strutted his way to Mamori, and gently, very gently he placed his head on her thigh. And whined cutely. Mamori laughed a little. It is a good sign, Cerberus thought.

"Thank you Cerberus," she gently patted his head. "I promise to still bring you food when I'm not part of the team anymore."

'Wait! What? No!' If only he had the ability to speak he would have already. That's when the door of the clubhouse had violently opened and to Mamori's shock she had grabbed/hugged Cerberus to her chest.

"Okay Fucking Manager time to- What the fuck are you doing?" Hiruma asked as to why Mamori was sitting on the floor, puffy eyes, and his hugging his devil of a dog.

"A-ah Hiruma-kun, i just um, I'm leaving the te-"

Cerberus growled in annoyance. 'Stop her you idiot!'

"-am, Sena does not need me anymore-Mppfh!"

Cerberus was so confused as to why one moment he was being hugged by Mamori, and the next thing he was discarded on the floor like a used shirt.

The dog glanced at space she was sitting and sure enough she was still there, backed on the wall by Hiruma. And he was kissing her, the kiss wasn't gentle at all. It was full of anger, frustration and pent up emotion the quarterback had been bottling in. When he stopped he slammed both of his hands on the either side of Mamori's head.

"I'm only going to say this once. So you better listen, Anezaki. First, that kiss isn't going to the threat book, you know I don't do things half-assed. Yes I wanted to kiss you, I needed to kiss you so what I will say will get into that thick head of yours. Second, I dont fucking care if the pipsqueak does not need you anymore. I still fucking need you. Why the hell do you think I burned the copy of the sign language? I already reminded you what you do for the team back in the field, what you do for me, in front of everyone."

Hiruma had stopped backing her on the wall already, Cerberus noticed the tension between them.

"So make up your mind. I meant every fucking word that I said." Hiruna said as he grabbed his laptop from the roulette table and was heading for the door.

"W-wait! Hiruma-kun." Mamori finally found her voice. "Let me- let's go together, to the Christmas Bowl." her voice firm.

"YA-HA!" Hiruma whipped around so fast and the next thing Cerberus knew they were kissing again.

OMAKE:

Cerberus couldn't shake the ominous feeling. He felt it the moment they have dropped Mamori to her house. He could literally feel Hiruma's stare at his back as he walked to the current hotel they are staying at.

The moment the door closed, he found himself staring at the end of Hiruma's gun. He sweatdropped.

"Don't go hogging all the attention of the Fucking Girlfriend you Damned Dog."

If a dog could smirk, he could have. He liked challenge.

'Bring it on' he growled. Maybe Hiruma forgot that he is not his master, but his equal. Now the mutt is looking to the best of 8 in Kanto Tournament.

A/N: I made this today, I think I'll start doing oneshots before I continue with my multichapter fic. Anyway, I missed writing for these two! And yes I might write the Best of 8 Kanto Tournament version of this story. Is still there any Hirumamo shippers here? 😁
