King's Heir (A Dadmare fic)

6

"Error, come here and get your jacket on."

"Yes daddy!" Error jumped off his bed, waddling his way to his father. Nightmare smiled, helping him get the jacket on with slight difficulty. The king chuckled, rolling up the sleeves so Error wouldn't have to deal with the darn things.

Cross came up once Nightmare finished with Error, "Papa? Could you help me with my scarf?"

"Of course, Ruru go grab your scarf as well."

"Okie!" Error yipped, running off to the closet. Nightmare chuckled, gently taking Cross's scarf from him. The king carefully wrapped the scarf around Cross's neck, tucking it in the back and finishing it off by making sure it was nice and comfy. Error soon returned with his scarf, the same black one Nightmare had given him years back.

"Alrighty..." Nightmare chuckled softly, watching as Cross smiled down at his little brother, "tuck or bow?"

Error perked up at the decision and pondered, "Bow!"

The god smiled at his son, taking the scarf from him gently. He did the same thing he did with Cross, only making a bow instead of tucking it back. The bright giggle that left Error made Nightmare smile. "Alright, go put your shoes on and we'll be leaving soon, and Cross don't forget your switchblade."

"Yes papa." Cross smiled, walking to the shoe rack with Error, helping the younger get his on first. Nightmare stood up, smiling. He waited until the boys were done, making sure they were ready.

As soon as everything was confirmed and made sure of, Nightmare opened a portal. The boys were the first to go through, their dad following close behind. The first thing they were faced with was the God of Death and poor Geno who was currently being harassed.

"Reaper fu.." Geno stopped midway when he noticed Nightmare and the two kids by his side. One standing tall and proud, stoic dare say. The other shy, hiding against the god's leg. "Oh... Nightmare? I didn't expect you to show up, much less..."

Reaper perked, immediately bowing down to Cross and Error's level. "Look at you two!"

Error let out a whimper, feeling uncomfortable only for Cross to step between Reaper's gaze. "If you could not direct my little brother in such a manner, that would be great."

Reaper huffed, standing back up. "Smart mouth for someone so young." The god looked towards the other. "These are your kids, Nightmare?"

"I can't imagine who else they would belong to... kids go ahead and play or look around, remember, steer clear of the punch and only drink clear liquids and don't take handouts from anyone but me, Cross you keep a sharp eye on your brother." Nightmare spoke gently, not in a commanding tone but more of warning and worry. The boys looked up at their father and nodded, Error immediately grabbing hold of Cross's hand.

"Yes papa." Cross smiled gently, looking to his brother, "You wanna take a look around Ru?"

Error only nodded. Nightmare watched them leave, his tendrils twitching behind him in a small bit of worried agitation, his boys were growing up too quickly. The king turned his attention back to the couple, humming in soft satisfaction.

Geno smiled a bit, "I didn't know you had kids Nightmare, who's the lucky person?"

"Oh no, I am very much alone." Nightmare chuckled, "I'm a single dad, those two are adopted."

"Really?" Reaper spoke up, surprised. "They look and act like you though, what are their names?"

"Error and Cross." Nightmare answered, "I adopted Cross a year ago, Error was given to me when he was a baby."
