Doofenshmirtz Elementary Science Class~!

Issei Hyoudou couldn't help but wonder where that tone came from when the new science teacher, Vanessa's father, entered the classroom. The brunette was still sad that Irina had to leave Japan for some other country, being alone had broken his heart, at least until Vanessa came into the picture.

She helped him get better as the days went by and the both of them had grown closer.

He was kind of excited that her father was going to be teaching them science, he had met Doofensh-Doof-

"━if you all have trouble saying my last name then you can just call me Dr. Doof or Doof-sensei! Now then, raise your hand when you are called and say present!"

Issei leaned over to whisper to Vanessa.

"Do you know why your dad decided to be a teacher here?" He whispered.

She shrugged and whispered back. "To be honest? I have no clue."

"You sound so embarrassed! You act like Heinz-san will do something stupid." The boy said to his friend.

"Because that's exactly what's going to happen!" Vanessa complained, rubbing her head. "I gotta ask Mom how she can even manage Dad with all the craziness he does at home. Not to mention how Dad and Norm made a cake that was bigger than our house for my birthday last year."

"Just give him a chance!" Issei chirped. "Plus, that cake was delicious! I'm not gonna complain about how big it was."

"Of course you would say that." The Half-Angel sighed. "Fine, I'll give him a chance."

"Yay!"

"Issei Hyoudou?" Heinz called from his desk.

"Present!" The boy raised his hand.

"Vanessa Doofenshmirtz, sweetheart?"

"Present." His daughter said with her hand raised.

It took a few minutes for Doof-sensei to get every student marked down. "Now that that's out of the way, let's get started. So, for today's topic..."

Issei was happy he met someone like Vanessa and her family, they made him happier than ever.


"And that, class, is how every part of the human body functions." The end of his lecture was followed by the sound of the bell ringing. He placed the textbook on his desk. "That's it for today. Class dismissed, go on and enjoy your lunch."

The kids in the classroom seemed to be impressed by the lecture and it looked like they had enjoyed it, which put a smile on his face. All the kids seemed to bring their lunch boxes, but some didn't feel the need to eat lunch yet, so they just chatted with their fellow classmates.

He sat down on his desk, preparing to eat as well, only to grab air. He began to look around his desk in a panic. "Come on, come on... Where is it?"

The students in his classroom began to notice his panic. They stopped what they were doing and gave their new teacher a look of concern, Vanessa walked up to her father with Issei following behind her.

"Dad?" She called. "You okay? You looked distressed."

"Darn it, I forgot the lunch Kemmy made for me.." Her dad grumbled as he sat down. "I'm fine Vanessa, I just forgot my lunch━"

He was interrupted by a knock on the door, he stood up and opened it letting the person enter the room. Every eye in the class was on the figure of a certain over-sized humanoid robot.

"Norm," Heinz placed his hands on his hips. "What are you doing here? Aren't you supposed to be at work with Kemmy?"

"Mom guessed that you would forget your lunch so she told me to bring it to you." The giant humanoid robot, Norm, held up a purple colored lunch box. "Here you go, Dad! It's still fresh!"

"Aw, thanks. You're a lifesaver!" He thanked his creation as he grabbed the lunch from him. "Relay a message to Kemmy for me that the food she cooks will forever be the best thing I've ever tasted."

"Got it, Dad." A beep sounded from him. "I'll be going back to Mom now. Hi and bye Little Sister!" He waved at Vanessa who waved back at him with a nervous smile before he turned and left.

"Doof-sensei?" A girl from his class raised a hand. "Who was that mascot?"

"Mascot?" Heinz raised an eyebrow, before waving it off. " That's not a mascot. That's just Norm, he's a robot I built! He's also Vanessa's older brother and godfather if you want to get into it."

A kid in the front row looked at Vanessa and flashed her a large grin. "Your dad is awesome, you know that? Last year, he even threw the best birthday party ever! What's your secret!?"

Everyone that was invited to Vanessa's birthday party seemed to nod in agreement only to leave the other, ignorant students confused but curious about what they were talking about. The rest of lunch was spent in the classroom talking about how great the Half-Angel's birthday party had been.

Vanessa's face was heating up from embarrassment while Issei tried his best to comfort her.


Two middle schoolers stood outside the school, where they had just seen an over-sized humanoid robot enter and then leave. The robot seemed to notice the two staring at him and waved happily at them.

"Hello there," He greeted. "Shouldn't you two be at school at this hour?" He gave a robotic shrug. "Oh well, not my problem."

With that, he flew into the sky with rocket boosters that were installed in his feet. The two middle schoolers stared at Norm as he flew off.

"Sona...?" The girl with red hair said, flabbergasted. "Was that... a freaking robot...?"

"Yes, Rias." The one called Sona said blankly, her gaze still focused on where Norm had disappeared.

"Yes, it was."


Doofenshmirtz Household

"Oh? So you must be the maid my husband hired, intriguing."

Viser, who now wore a maid uniform, turned her head to the front door as a woman and a... robot... An honest to god robot entered the house. She took a good look at the woman with white hair, then recalled the picture Heinz showed her.

Kemuel Doofenshmirtz, in all her glory, waved at her with a smile.

"Hi, my name is Norm the Robot!" The humanoid robot offered a hand, Viser took the handshake instinctively with a blank look. 'Of course, he has a fucking robot. How did I not think of that?'

"V-Viser, newly hired maid of the Doofenshmirtz household." The former Stray Devil introduced herself and let go of his hand. "Pleased to meet you, Norm, Ma'am."

Norm turned to the Angel, "Shall I make tea Mom?"

"That would be most appreciated, Norm. Please do." She thanked the robot, who walked towards the kitchen leaving the two of them alone in the living room.

"Take a seat." Kemuel began, Viser obeyed, and both made themselves comfortable. Kemuel started leaning towards Viser, who yelped at the action.

'Too close!'

To her relief, Kemuel stopped what she was doing and crossed her legs with an unreadable look on her face. "My husband said he used one of his Inators to turn you into a human, yes?"

"Yes, Ma'am." Viser answered, their conversation was cut short as Norm returned with a tray of tea.

"Here's your tea." Norm placed the tray on the coffee table. Kemuel grabbed a cup of tea and took a sip, a satisfied look crossed her face.

"Delicious as always, son." She praised him.

"Your praise will always warm my heart." Norm said happily, "If you excuse me, I will prepare dinner before Dad and Little Sister get home."

Norm left them alone as the two resumed their talk.

"Where was I? Ah, yes. The Inator Heinz used on you seems to have a side-effect from what I've observed of you and the magical energy flowing within you." She stated.

Wait what?

"It would appear that despite being a human, you can still wield the Demonic Power all Devils possess." She giggled to herself. "I can only imagine how livid those fools in the Underworld would be if they found out a human such as yourself could use Demonic power, it's even more hilarious that you were formerly a Stray."

She placed her tea down, "Why don't you try manifesting that power? It wouldn't hurt to give it a shot, yes?"

Viser blinked several times, and seemed to space out. She panicked that she had done that in front of Kemuel, but she was only amused at the sight. Viser calmed herself and began to pour the magic she had become familiar with over the years into her fist, a bright blue glow manifesting as her fist was coated in bluish flames. She let the flame dissipate and stared at her hand, deep in thought. She snapped back to reality when she heard Kemuel laughing lightly.

"It would seem my husband is oblivious to this change of events, but it is a welcomed one." She stood up at her full height. "Welcome to the family, Viser."

"Please take care of me, Lady Kemuel." She bowed, she felt someone touch her head and looked up to see Kemuel patting her head with a motherly smile. The sound of a door opening caught their attention and saw Heinz and a red-faced Vanessa entering the living room.

"Kemmy, I'm home!"


Underworld

"Rias, it's rare for you to call me. To what do I owe the pleasure?" Sirzechs Lucifer said, his phone to his ear.

"..."

"Robots? Are you feeling unwell today? What gave you that idea?"

"..."

"What?"

"..."

Before the Satan could reply to his sister, a woman in a magical girl outfit burst into his room with a phone in hand.

"ZECHS-CHAN!" Serafall Leviathan, a fellow Satan of the Underworld, shouted. She shoved her phone at him and showed him various pictures of the supposed robot Rias had mentioned entering and exiting an elementary school.

"YOU OWE ME THAT BET WE HAD THAT YOU'D WEAR A MAID OUTFIT FOR A WHOLE YEAR IF I PROVED THAT ROBOTS ACTUALLY EXISTED!" Sirzechs stared at Serafall in horror, his gaze catching his mother holding a maid outfit with a nasty look on her face. The Satan could only gulp at the sight of her with stars in her eyes.

With no other choice, especially not convincing them to change their minds, Sirzechs dived through one of the office windows.
