"How come you are here, Oga?" Asked Yuki as he fed baby Beel some of his food while he kept running from one demon to another with sparkling eyes…

"Well, this idiot kept bugging me about taking baby Beel out and we just happened to pick this place" Replied Oga while pointing at Hilda causing veins to pop on her head so she slightly unsheathed her sword showing him what kind of fate awaited him if he kept talking nonsense so he instantly changed the subject.

"What about you? how come you disappeared for such a long time? Baby Beel wanted to see you many times but I couldn't reach you on your phone…"

Yuki looked at baby Beel and noticed the angry stare he was shooting him so he apologized and said "Sorry about that, I had some business overseas and I just recently came back"

"Ah, that's understandable" Replied Oga not thinking much of it, although Yuki could tell that Hilda was shooting him a suspicious stare…

Not long after, they finished their meal and went to see the rest of the attractions in this park, and there were plenty of them, but baby Beel seemed attracted to a huge pirate ship and kept tugging at Yuki's hair to go to it so Yuki couldn't help but say "You want to go there?"

"Tabou" Replied baby Beel with shining eyes while nodding his head so Yuki started walking there with Oga who can't separate from baby Beel less he wanted to get electrocuted... Meanwhile, the rest each went to do whatever they wanted…

Yuki noticed Rize shooting them many glances from time to time but he didn't pay her too much attention and simply focused on having fun…

"This pirate ship looks quite realistic…" Muttered Yuki and Oga nodded in agreement as they both boarded the ship. However, that's when Yuki's vision suddenly shifted and he saw a huge azure sea with countless islands scattered like the stars in the night sky.

However, what attracted him even more was a giant red mountain chain that appeared to be splitting this sea in half…

'This is… It feels familiar…' Suddenly, something popped in Yuki's head 'Is this what I think it is?' Countless ships floated on the sea of this world, and for some reason, he could tell that a lot of them were pirate ships! Something he wouldn't find in most worlds and especially not this one!

'I left everything this world has to offer in that place... FIND IT!' A voice suddenly reverberated in Yuki's head shocking him to the bones and forced him to wake up from his vision…

"One piece…" Muttered Yuki in an absent-minded tone as he stared at a notification that appeared in front of him…

"Tabou?" "Is everything alright?" Asked baby Beel and Oga showing concern on their faces after they noticed the look on Yuki's face.

"I'm fine" Said Yuki while smiling to ease their worries and patted baby Beel for how cute he looked before they started exploring this pirate ship and even took some pictures in pirate costumes and all the while thinking 'Did baby Beel notice something?'

...

However, the fun didn't last for long as suddenly, they heard the sound of something exploding and the people appeared to be running from a covered building in the park that had multiple pools inside as well as attractions.

"Isn't that where Hilda and your friends went?" Asked Oga with a surprised look and Yuki instantly had a different look on his face since the girls went together there!

"Let's go" Said Yuki before he directly started running towards the sound of the noise 'Hopefully Shizue and Emilia will keep the others safe' Thought Yuki before he used his special communication function with his servants;

"Shizue, what's happening?"

There was some silence, but not long after, Shizue responded to Yuki with a rushed tone "We were attacked by three demons, although their target seems to be principally Hilda, but they are using Mashiro-chan and Chiho-can to distract us making it difficult to fight them... Thankfully we received help and Emilia is taking care of them"

Yuki's eyes instantly turned ice cold as he rushed even faster and said "Help huh? Don't worry, I'm on my way as well!"

…

Earlier, when Yuki was taking pictures with Oga and Baby Beel, three people suddenly appeared in front of the girls. They were the same ones that Rize noticed as she was trying to avoid their group.

They were Naga, Hecadoth, and Graphel, three demons that came from the same world as baby Beel and Hilda and their mission was to probably pave a way for their young master to become the next demon king by killing Oga…

Naga was the leader of the two, and Shizue instantly took him on since she was the far superior person when considering physical attributes alone without the use of magic. In contrast, Emilia took on Hecadoth while trying to minimize the use of her magic, while Hilda faced Graphel.

"How dare you attack us like this in broad daylight? Is this behemoth's doing?" asked Hilda with an angry look since the competition between the demons shouldn't be like this

"You are in no position to ask us questions, lowly maid" Replied Hecadoth arrogantly causing Hilda's face to turn even more hideous as she turned to Emilia and Shizue and said "Sorry about this, and please be careful, these guys are powerful"

"Don't worry, I don't mind killing off scum like this" Replied Emilia coldly while Shizue simply deflected Naga's attack and analyzed the situation calmly 'Mashiro and Chiho are going to become a burden soon if we don't move them away from here, I should create an opportunity to allow them to escape'

However, just as she was thinking this, Graphel suddenly smirked and pushed Hilda away and rushed at Chiho!

"You dirty bastard!" Hilda was caught off guard as she didn't think they would involve a normal human, but this is how demons act after all…

Chiho froze slightly but she still glared at Graphel and said "Don't worry about me, I will be fine" even though she was in no way going to be fine… However, a woman suddenly appeared in front of her and smacked Graphel into the wall using a red tentacle that emerged from her back…

"Oh, I guess I got here right on time"

"You!" Emilia was surprised by who gave them a hand, but she simply smiled and turned her attention to the demon facing her " It seems like it's time to kill some demons!"

….

As Yuki made his way to the fight scene, he arrived at the same time as Maou and the rest of the creeps, and they were relieved when they saw everyone was fine… Although there were no signs of their attackers

"Where's the enemy?" asked Yuki while scanning his surroundings coldly but Shizue simply smiled warmly at him and said "Emilia-san went crazy and killed them"

"Don't say such things with a smile, that's creepy…" Said Yurei with a nervous smile on his ugly face which received him glares from everyone.

Meanwhile, Yuki heaved a sigh of relief, but he was now faced with another problem… Mashiro saw everything… but he first needs to deal with that woman "Thank you for giving them a hand"

Rize nodded silently before she responded "I'm going back now, I don't think you will need further help from me"

Yuki nodded calmly at her before he said "You can find me if you ever need help in the future"

Rize was surprised slightly but she didn't take it to heart since she only wished they forget their enmity towards her, so she simply nodded and turned around to leave but Chiho ran back behind her and thanked her from the bottom of her heart shocking the cruel ghoul who didn't know what to do…

Meanwhile, as Rize was having her awkward moment, Yuki was having his own as he left Maou to discuss with Hilda about the identity of their attackers while he faced Mashiro awkwardly

"Mmm, Mashiro-chan, have you enjoyed this show? The production was high level wasn't it?" spoke Yuki while putting Maou's greeting smile on his face but Mashiro simply tilted her head at him and said "I knew"

"Oh, you knew? That's great… wait! What did you know?" Yuki suddenly had a bad premonition and he couldn't help but shoot Emilia a stern look, and seeing her turn away from him while playing with her hands nervously only made his heart sink even more…

'Don't tell me… This idiot exposed everything!' Thought Yuki before he turned to Mashiro and he heard her say "I know that all of you are not normal except for Chiho-chan"

"Oh... I see" A terrifying calmness suddenly gushed from every pore of Yuki's body… He always tried to protect Mashiro from their crazy world, so he always tried his best to hide the truth from her, but now it seemed like someone already ruined his plan, and he wasn't even informed about it…

"Who knows that you know?" Asked Yuki with a warm smile and he noticed from the corner of his eyes Emilia's panic increasing…

"Maou-san and Emilia both know… they fought once in front of me so they had to explain the situation to me"

"I see, Maou and Emilia huh?" Yuki had a weird look in his eyes as he turned to Maou and Emilia and a terrifying aura started gushing from his body, a combination of his wicked thought, conqueror's Haki, and killing intent and it gave them chills!

Even those that weren't directed at them felt like a true disaster was standing in front of them at the moment, and this included Hilda and Oga who felt out of breath as Yuki moved toward Emilia and Maou and punched them both on the head causing them to be buried into the ground…

"Anyone else knew about this?" Asked Yuki eerily and Ashiya couldn't help but think 'This bastard is finally showing his true colors *Gulp*'

Mashiro put on a contemplating look on her face before she pointed at Yurei and said "I saw him walking through walls many times absentmindedly, but I don't know if he does know…"

"WAIT Yuki! I can explain!" Yelled Yurei, but Yuki didn't care at all and simply beat him up until he felt satisfied before he turned to Mashiro and asked seriously

"Do you want to forget all of this? Knowing these secrets will only turn your life into a mess…"

However, Mashiro simply stared at him like an idiot before she tried to imitate him and punched him gently on the head before she said "Yuki, idiot… I don't care who they are, they are my friends"

Yuki froze slightly before he smiled warmly at her and rubbed his head where she hit him before he said "Ouch"

But three angry fellas suddenly emerged from the ground and punched him in the head returning the favor as they yelled "Don't you dare act cute after hitting us that hard!"
