The Saint's Trial: Can He Resist Their Charm!?

"Hey Hiroto, do you want to come to visit us at our house? There is a onee-chan there that you can play with!" Sirzechs said, inviting the little boy to play at their house. He is quite fond of this little boy, he invited him since hey thought that Rias would love to play with a social butterfly such as this kid.

"Ahahaha, I'm sorry if my boy is quite rude to you Maou. Hiroto is just exited about seeing new faces. When I told him that there is someone who would be visiting, he was elated and couldn't even sleep last night. This is his first time seeing someone other than dragons! Hahahaha!" Tanin laughed boisterously remembering what happened last night.

"Hey Fathe... Papa! What is a Maou?" knowing that he couldn't pronounce the word correctly, Hiroto stopped before he can say it. The boy didn't know that his antics warmed the hearts of the people around him because of his cuteness.

"Hmmm, well a Maou is super strong! They rule over the whole underworld! It's like Papa being the leader of the dragons here but he has more people," Tanin explained enthusiastically. Hiroto who heard his explanation have sparkles in his eyes as he looks at Sirzechs like he's some popular actor he saw for the first time, completely amazed. Before long, Hiroto recovered from his amazed expression, he spoke, still having those sparkles in his eyes.

"Wooooooww! Awe you weally, weally, weaaaaaalllyy mowe powewful than Papa?! You'we amazing Siw Maou!" the little boy shouted while waving his arms up and down.

Bathing in the glory of being looked at with amazement by this young boy, he has this smug look on his face, completely satisfied with this situation. Grayfia who saw the smug look on his face had a tick mark on her forehead, she pinched his waist before twisting it hard. Feeling the pain on his waist, Sirzechs' smug look crumbled, replaced by a face looking like he swallowed a bitter pill.

"O-Ouch Grayfia, could you please let me bath in the glory of being praised by a cute child just this once? Try being praised by this bubbly child too and you'll understand how I feel when Rias and this child praise me!" Sirzerchs said to Grayfia seriously. Grayfia just rolled her eyes at him but she didn't expect him to really ask the little guy to tell something good about her.

"Hey Hiro-chan, I can call you Hiro-chan right?" asked Sirzerchs at Hiroto after approaching him before he knelt down, speaking to him at the eye level.

"Un! Maou can call Hiwoto Hiwo-chan! Hiwoto is always called like that by the dwagon onee-chans you know?!" exclaimed Hiroto.

"Ohhh is that so? Then I'll call you Hiro-chan from now on ok?" said Sirzechs looking for confirmation from the child.

"Un! Of course Maou can call me Hiwo-chan!" said Hiroto while puffing his c.h.e.s.t out with pride for some unknown reason.

"Hahaha ok then Hiro-chan, I have a question for you. What do you think about this silver-haired onee-chan that came with me here?" he asked to Hiroto.

"Um um, onee-chan is soooooo beautiful! And and, she has the same haiw colow as mine!" Hiroto answered with a child's honesty.

Grayfia who heard this cute child praise her so enthusiastically, puffed up her well-endowed c.h.e.s.t with pride.

Seeing her reaction from being praised, Sirzechs have the urge to tease her but before he could, Grayfia looked at him while emitting a dark and cold aura. Her cold smile that is directed at him sent shivers down his spine so he forgot about the idea of teasing her.

"A-Anyway Hiro-chan, you should come to visit our house tomorrow ok? Your new playmate would be happy to meet you!" he said at Hiroto before telling Tanin that they will take their leave now.

"Goodbye Maou! Hiwoto will visit you tomowwow ok?!" Hiroto said while waving his hand enthusiastically.

"Ok then, we will see you tomorrow then!" said Sirzechs while laughing before continuing to speak, "Hahaha that little one sure is energetic, I didn't expect Tanin to have such a cute and bubbly adopted son," he said, amazed at the thought of the all too serious Tanin having a bubbly son.

"Fufufu you are right. The little guy is so energetic and cute, I would like to have such a child in the future," said Grayfia with a sad glint in her eyes.

"I hope that you can achieve that dream of yours in the future," said Sirzechs with a caring and concerned tone in his voice. Grayfia who heard the concern in his voice looked at him with a grateful expression before saying.

"I just hope that the civil war in the Underworld would end quickly, I thought that our acting and fake marriage would be enough to end this war but sadly we were wrong," said Grayfia.

"You don't have to worry, I will do my best to end this war and bring peace to our land. I just hope that you too, could find your own happiness in the future," said Sirzechs while looking at the far-out horizon with a hint of melancholy in his eyes.

"Okay, enough said. Let's hasten our pace so that we can inform Rias about the good news! I'm sure she'll be delighted!" said Sirzechs. Grayfia who heard him created a magic circle with the symbol of Gremorys in it. A few seconds later, they were engulfed by a crimson light and disappeared from where they previously stood.

=====

Hello! My name is Hiroto and my Papa said that he adopted me because he saw me left behind in a very, veery scary monster's nest! Shocked right? I am too! I was surprised that my real parents left me there. But my Papa said that I shouldn't hate them because, they probably have an veeeerry important reason! So I became a good boy and listened to my Papa!*

(A/N: You might be curious as to why he said the word 'R' so correctly, so why was that? It's because this is kinda like his Diary or something. So of course he can write it just fine.)

"Hehehe Awen't I amazing?" said Hiroto with a smug look on his face.

Oh! oh! I forgot! Today is the day that I will visit Maou's and Silver-oneechan's house! Amazing right? They said I will have a new friend too! I like new friends! That's why I woke up early so I can go there early too!

I and Papa are on our way to Maou's house right now. I am standing on his head while holding his big biiiiggg horns! It feels amazing to ride on a dragon you know?

Reaching our destination, we were greeted by Maou and Silver-oneechan. How nice~ It's good to see them again! I checked the other people lining up with them, there is a brown haired Onee-san and a red-haired oji-san with a hair growing on his chin! I wonder what that is? Isn't it uncomfortable to have a hair in your chin?

Thinking about all this, Hiroto is touching his chin, checking out if he has some hair like the Oji-san that he saw.

We landed on the ground a few seconds after, me and my Papa greeted them first before I ask them a question I am thinking for quite some time now, I can't help myself tehee.

=====

"Umm Oji-san, what is that haiw that is gwowing on youw chin? Doesn't it feel uncomfowtable?" Hiroto asked this while looking at the red-haired Oji-san. Looking at the curious little guy that is tilting his head to the side, Zeoticus could help but be fond of such a curious and bubbly kid. Even the ladies of the Gremory Family and the maids were entranced by the cuteness they are seeing.

"Ah! Hello young lad, my name is Zeoticus. You can call me Zeoticus-ojisan you know?" said Zeoticus to Hiroto with a kind smile on his face.

"Ummmm, Zeo-ti... Ummm, I'll call you Zeo-ojisan okay?!" said Hiroto while looking at Zeoticus for confirmation.

"If it's hard for you to say it then you can call me that too," said Zeoticus reassuringly. After that, Venelena stepped forward and hugged Hiroto. Surprised by the sudden turn of events, Hiroto had his eyes wide open

"Fufufu, sorry if I surprised you Hiro-chan you were just too cute so I can't help but hug you~," said Venelena, still hugging Hiroto.

"U-Um, it's ok Onee-chan!" replied Hiroto before hugging Venelena back. Venelena was surprised for a moment before she broke their hug, still holding Hiroto's shoulder she said, "You are such a good child even calling me Onee-chan, how cute!" said Venelena while pinching his cute face. Suddenly, a jealous voice interjected.

"How long are you going to hug him, mother?! Quickly let go!"

Looking at the direction where that voice came from, Hiroto saw a girl with blue eyes like him and a crimson hair. She looks cute with her mouth pouting while looking at Hiroto and Venelena enviously.

"Ara Rias, you can't be like that you know? You are the Onee-chan now so you can't be jealous all the time," said Venelena to her daughter, slightly reprimanding her.

"Ohh! You are my new fwiend wight" he asked her with a glint of anticipation in his eyes.

"Hmpf, I don't know you so don't talk to me!" Rias said haughtily. Venelena wanted to reprimand her again when Hiroto suddenly spoke.

"Oh umm, sowwy I fowgot to intwoduce myself. My name is Awiyoshi Hiwoto! Oh and, my Papa is Papa you know?" said Hiroto while extending his hand for a handshake. Being the aristocratic little girl that she is, she just harrumphed and gave him the cold shoulder.

And the bubbly young boy and the crimson-haired girl with a princess syndrome met. How will Rias' princess attitude affect their future? You will find out of course in the future too!

(A/N: The MC is still a kid in mind and body, and I'm not gonna follow those other reincarnation novels where the MC just starts doing push-ups after a few freakin' years! That's just too illogical if you ask me. And seeing a kid acting like an a.d.u.l.t is creepy as hell! Watch that Baby Boss something movie to understand what I'm trying to convey here! So the system and the Menu will be introduced after a few more chapters about his childhood. Oh and as the cover says, this Arc is not gonna be at DxD for long~ You will find out why in a few more chapters so 'Stay Tuned'!)
