Haru sit down in his new room with Astra and Caster, fortunately after Caster teleported them out they did not encounter any other problem along the way.

"Ahh... that was rather close..." Astra stretch his body and lie himself down, both of his hand behind his head. "So that was magic huh, the Berserker guy is definitely strong and that girl seemed to know me, I'm totally not feeling it."

"What is your plan next, Master?" Caster asked, her appearance change a bit as she didn't raise her hood, with her blue hair in the open she look like a very rich and beautiful noble lady from foreign land.

"First we're going to wait for the other to come and then we're deciding where we go from there." Haru said, looking at his driver. "What do you think we should do Caster? I'm not experience in this kind of stuff so please help us." Haru said, lowering his head.

"If you ask so nicely how can I refuse?" Caster smiled mischievously. "First let me set up my workshop first, this place will do."

Haru nodded. "Sure, as long as you make sure not to involve Fujimura-san and her family."

"Who do you think I am Master? There is no way I do such an unnecessary thing as involving bystander." 'Unless I need to do so. "If there isn't any more to talk I will go and prepare my workshop." Caster starter to walk away.

"Wait!" Astra called out, stopping her.

"Yes?" Caster turned her neck around.

"Can you show us some magic? I'm totally want to real magic!" Astra stood up and come closer to her, big grin on his face.

"..Alrigh-"

*Beeb!*

Before Caster was able to finish her sentence Astra and Haru seven code band rang, both of them active their band.

"Haru, Tora! There is an enemy, Dosukomon and I are fighting him right now!"

"Eri-san/Eri!"

-0-

"It's already dark."

Eri sigh, she was a little bit late on coming here, she need to get her manager to arrange her indefinite vacation time on Fuyuki 'I'm sorry manager.' She thought, her manager after all is a nice woman who act like a family to her, the number of paperwork she need to fill is high, she just hope that there is nothing happen to Haru before she arrived.

"Don't worry Eri-chan, Astra and Musimon has gone here first, if there is something going I'm sure the seven code band would have rang already." Beside her, her buddy appmon Dokamon said with a smile, the blue fighting dragon know her well.

"You're right Doka-chan." Eri smile at Dokamon. "Wh-" Suddenly her vision was greeted with a grotesque sight, that is of woman who heart has been pierced from one side to the other by a blood red spear wielded by what seemed to be a man in blue.

Eri gasped in surprise as the man turned his attention toward her; the man was wearing a displeased expression.

"Someone wandered in and a little girl nonetheless..." The man shook his head. "I'm sorry, I rather not kill a little girl but the bastard is telling me too."

In an instance the man disappear from her sight and the tip of the blood red spear was right in front of her chest.

"Eri-chan!" Dokamon scream as Eri was blown away a few meter back.

Eri quickly regained her bearing and stood up. "Doka-chan!" She shouted as Dokamon caught spear with both of his hand.

"Oh?" The man in blue look at Dokamon, impressed. "What are you little thing? Your presence told me that you are not mystical in nature." He asked curiously.

"I'm Dokamon and for trying to kill Eri-chan you will pay!" Vein-like line started to appears in Dokamon arms. "Take this!" Dokamon lifted the man with his spear and throw him into the distance.

"Eri-chan!" Dokamon shouted.

"Alright!" Eri took out her AppliDrive Duo and Dokamon fly into the seven code band on her wrist.

"Apprealize Dosukomon!"

"I'm ready to beat you up, Dohyo Field actived!" Dosukomon slam both of his feet to the ground, causing everything to shake as the jet engine on the back of his arms and his waist spit out small flame.

"Hahahah... Interesting!" The man spin his spears and took a stance, pointing the tip of the blood red spears toward him. "I don't what you did but I get the feeling that only one of us will leave this battle."

"If you consider yourself a warrior then this is just a formality." Dosukomon said as one of his fist on the ground as the jet engine on his body roars.

"I don't know about that but I have a feeling that I will enjoy this battle, Dosukomon right? You may call me Lancer." The man who called himself lancer grinned.

In flash both of them disappears.

AN: For those unaware, Dohyo Field is Dosukomon special skill where he draw his opponent into sacred one on one battle where both party unable to retreat no unlike the duel geass used in Hollow Ataraxia.

Trivia: The Appli Monster cast was named after AI or or something related to that and their name when written in Romaji what it was based off.

Haru is is a Reference to HAL one of the first major AI in cinematic fiction.
Eri aperfect acceptable Japanese name, could be transliterated to reference Ellie, the first AI that was able to successfully imitate empathy.
Yuujin, a kind-of-rare but still acceptable Japanese name, could be transliterated to reference Eugene (Goostman), the first chatbot AI that claimed to pass the Turing Test.
Rei, a really common Japanese name, could be transliterated to reference Ray Kurzweil, a programmer who is actually currently working on designing real life AI, and wrote the book that predicted that the AI singularity will occur in 2045(which is the time Appli Monster take place). Interestingly, Rei is also a Japanese word for "Zero", and Hajime's name can be written with the Japanese character for "One", referencing the building blocks of computing.
Ai, a really common Japanese name, could literally just be referencing "A.I." due to the spelling of her name.
