Okay, my Konosuba steam is going really strong right now, and I really wanted to provide some more backstory for my OCs Kizui and Grace from Back to the Future of this Wonderful World. So, I decided to write a neat little story about their childhood and early teen years! Maybe I'll write a full-length story about them some other time, but I'm still in the experimental phase.

"Are you okay?" said Kazuma, as he and Megumin walked through the field. Ever since his girlfriend had turned sixteen, she had seemed a lot more anxious than usual. Having a girlfriend was a strange new experience for him, even without taking into account that it happened to be Megumin of all people. Kazuma barely even remembered how he ended up so lucky. And yes, he understood the irony in that statement.

"I-I'm fine," Megumin blushed. She really wasn't. Her palms were incredibly sweaty; she could hardly keep a grip on her staff. She couldn't believe she was doing this. "This looks like a good spot!"

She pointed to Verdia's old castle.

"That one?" said Kazuma. "We haven't done that in ages."

"Yeah…" Megumin took a deep breath. No turning back now. She extended her wand. "Kazuma!"

"Yes, I'm Kazuma,"

Megumin's wand started glowing red.

"Long ago, I wandered alone, searching for companionship," Megumin chanted, "Then I met you, and you accepted me for who I was, ending my endless solitude. Every single day, my feelings only grow stronger for you. And now, at the place where we spent so many memories together, I beg you to grant me one last request,"

"Huh?" said Kazuma. This wasn't her usual chant.

Megumin then twirled her glowing staff like a baton and fired the spell downwards. Kazuma lost his words when a towering column of fire flew out of the canyon, and Megumin turned to face him.

"Become my eternal lover," Megumin got down onto one of her knees and pulled a golden topaz ring out her pocket. "Marry me,"

For the first time in nearly a year, Kazuma was speechless.

"M-marry you?" I mean, she is sixteen… but I was never expecting this! Also, I thought I'd be the one to propose. He looked into her crimson eyes, glinting in the light of the fire. Ah, who am I kidding? She's probably the best thing that's happened to me to since I reincarnated here.

"Of course I will," he said.

Megumin smiled and caught him a tight embrace.

"Woah, Megumin…"

"I'm so happy," she said, her eyes started to tear up. "You mean everything to me, Kazuma."

"I love you."

"I love you too."

About a week later…

"We're getting married!" said Kazuma and Megumin.

Darkness and Aqua simultaneously spat out the water they were drinking.

"What?"

"Megumin popped the question last week," Kazuma explained.

"Wow," said Darkness. "Congratulations!"

Aqua sighed.

"Great. Now I owe Eris 1900 eris,"

"Speaking of which…" said Vanir. Wiz sighed and handed over a few coins.

"That reminds me," said Megumin. "Yunyun, Aqua, Darkness, do you mind being my bridesmaids?"

"Absolutely!" said Yunyun.

"Certainly!" said Darkness.

"Eh, why not?" said Aqua.

A month or so later…

Kazuma gleefully carried his new bride to their shared bedroom. He wore a green tuxedo, while she wore a black and white fusion between a wedding dress and a suit of armor. Since Crimson Demon weddings have the bride in a black armor-like garment, they agreed to meet halfway in terms of tradition.

"Oh, I almost forgot!" Megumin hopped out of Kazuma's arms to throw the bouquet out the window. "Catch!"

"I got it!" Darkness dashed over to the flowers, but Aqua leaped onto her shoulders to snatch them out of the air.

"Aha! Now I'm the next bride… Woah!" The two of them toppled onto each other.

"Ow…" said Aqua. She then noticed that she had somehow landed in such a way that her chest was right on top of Darkness' neck, and her leg was between hers.

"Oh…" Darkness blushed. "I didn't know you were into this Aqua,"

"D-don't get the wrong idea!" but Aqua couldn't hide the redness on her face.

Kazuma and Megumin giggled at their friends' antics.

"Well…" Megumin seductively laid herself on the bed. "Since we're husband and wife now, do you think you're ready to take "virgin," off your list of titles?"

"Absolutely," Kazuma started taking his shirt off.

A while later…

Kazuma examined the large painting in the living room.

"I think it captures my strength and power perfectly," he smugly grinned.

"Oh, Kazuma." Darkness sighed.

"Ugh, he did my hair wrong," said Aqua. "It's supposed to be flowing! Not fluttering! Water does not flutter! It flows!"

"Guys, guys!" Megumin came running over.

"What is it?" said Kazuma.

Megumin stopped in front of Aqua.

"I think I might be pregnant!"

"What?" said Aqua. She turned to Kazuma. "Kazuma…"

"Yes, I'm Kazuma,"

Aqua grabbed him by the neck and pulled him up to her face.

"YOU LOLICON! WHAT IN THE NAME OF ME DID YOU DO?"

"First of all, we're married!" said Kazuma.

"Second of all, I'm seventeen!" said Megumin.

"Oh right," Aqua dropped Kazuma. She raised a hand in front of Megumin. "Sense Life!"

Aqua concentrated as her hand glowed.

"Okay…" she took her hand away. "Congratulations, you're pregnant!"

Megumin's eyes literally lit up with delight.

"YES!"

"Well…" Kazuma cleared his throat. "I probably should've seen this coming."

Megumin glared at him.

"I mean, this is great!" Kazuma piped up. "Sure, I might be dysfunctional, but that's not genetic, right?"

"Who knows?" said Megumin. "Well in five months, I'll be a mother and you'll be a father!"

"Yeah… a father," Kazuma took a deep breath. "Holy crap I'm gonna be a dad,"

"Did you say five months?" said Darkness.

"Crimson Demon, remember?" said Megumin. "Our bodies are mostly magic, so we only stay pregnant for about five months,"

"Oh… I guess that makes sense," Darkness began to ponder.

"Oh yeah, you're pregnant too, Darkness," said Aqua nonchalantly.

"WHAT?"

Both Kazuma and Megumin grabbed Darkness by the neck.

"YOU PERVERT MASOCHIST! WHAT IN THE NAME OF ERIS DID YOU DO?"

"Nothing, I swear!" she exclaimed. "I mean, the only person I was with sexually was Aqua!"

"Aqua?" said Kazuma

The goddess in question whistled idly.

"I mean… she was pretty good," she said.

"Well that doesn't make any sense; Aqua's a girl!" said Megumin.

"Well…" Aqua blushed. "Goddesses technically don't have a gender."

"What?" said Darkness.

"We can change genders whenever we like so it's more preference," she blushed even harder. "But I can still… you know… impregnate other women"

Everyone was silent for a moment.

"OH MY GOSH! AQUA'S THE FATHER?" said Kazuma.

"It would seem that way," said Megumin. "Well, congratulations!"

"Yeah… congratulations…" Aqua sat down. "Oh my me, I'm gonna be a mother."

"Is it weird that I'm kind of okay with this?" said Darkness.

"For anyone else, yes," said Kazuma. "For you, no."

"Thanks."

Five months later...

A whole year after they were married, Kazuma and Megumin brought home a daughter.

"She's so cute!" Aqua cooed. "What's her name?"

"Uh…" Kazuma rubbed his chin.

"Kizui," said Megumin. "Her name is Kizui,"

"Kizui?" said Kazuma.

"She's a Crimson Demon," Megumin pointed to her daughter's scarlet eyes. "One syllable from you, two from my mother. That makes sense,"

"I guess. Kizui it is then. Kizui Satou," Kazuma smiled. "At least it's a better name than Chunchunmaru,"

"Hey!"

Kazuma laughed.

"This life was definitely worth dying for,"

Kizui gave out a little giggle, as her eyes lit up for a moment.

"Aww!" Darkness squealed.

"See that glow?" said Megumin. "She'll be a powerful sorceress someday!'

"Either that or she needs a diaper change," said Kazuma.

A few months later…

"Kizui, this is Grace," Darkness held her daughter up for Kizui to see. Kizui's eyes literally lit up and she smiled. Grace simply stared and blinked.

"I'm still a little baffled as to how you two had a kid to begin with," said Kazuma.

"Hey, don't look so condescending!" Aqua held Grace up to Kazuma's face. "This is a future goddess of the Axis sect!"

"Hm," Kazuma stared intently at the baby. She had a small tuft of lime green hair, as well as two-toned eyes, one yellow one blue. "Looks more like some kind of witch,"

"EXCUSE ME?"

Everybody laughed.

And so, with two new additions to the family, life would be taking a whole new direction for Kazuma and friends.
