A man in his twenties walked alone in the very late night at the edge of the city. In a world where Supernatural existed, such thing as walking alone much less nearby a forest the man was at risk to get killed yet nothing happened to the man. Instead meeting a monster, the man meet a girl dressed in magical girl costume with wand in her hands.

"Do you know what time is it, Serafall?" Annoyance clearly showed in the man's face.

"Mou~, El-tan. There is always time for justice." The girl in Magical Costume, Serafall, twirled her wand and posed in a way where normal boys and men could resist.

Now named El-tan shook his head seeing the childish behaviour for a Maou. "Still dreaming for Magical Girl, i see."

"Nu-uh. Serafall is not dreaming as a Magical Girl. Serafall is a Magical Girl." Serafall pouting furiously at El-tan. "Seriously El-tan, Serafall is hurt. Serafall just wanted El-tan to show his support for his girlfriend."

Ah right, she was his girlfriend for 200 years now. Despite his opposite race to Serafall, his relationship with her was normal, just like other couple although he had to tolerate her dream to become a Magical Girl. She also the only one who knew what race he was as most Supernatural beings or someone knowledgeable about supernatural saw him as Immortal Human.

"Hai hai, Serafall is a Magical Girl." El-tan resigned to what his girlfriend wish.

"Yay, El-tan is the best boyfriend for Magical Girl Levi-tan ever." Serafall ran and hugged El-tan with a force enough to destroy a small house. Fortunately her boyfriend was anything but normal so such force couldn't hurt him in the slightest.

Still lacthed to him, El-tan asked why she was here. Girlfriend or not, anyone that disturbing his peaceful sleep was someone he absolutely hated and Serafall knew about this. So the only conclusion he got was something bad was going to happen to someone that very important to her.

"The truth is Elliot, i heard some bad rumors about the town my sister and Sirzech's sister managed. Not only that, a boosted gear user is found in that town so you know what happen if its counterpart actively seek the boosted gear user. I just don't want my sister got hurt." Serafall whispered in suddenly-changed-into-Elliot's ear. As Maou, she couldn't show any favoritisme to anyone. The only one she could ask for help was Elliot, someone who was known as Immortal Human, a neutral party, her boyfriend under pretense visiting his girlfriend sister.

"Alright, i'll help you but until Devil side can think better solution." A cheerful 'Yay' came from Serafall.

"El-tan is the best."

Sona Sitri or Sona Shitori as most residents of Kuoh Academy know her, Student Council's president, was pacing back and forth in her office after received a letter from her childish for a sister, Serafall, today. Normally she would ignore everything whatever her sister sent but today she couldn't afford such thing because her idol or known as her sister's sadly-roped-as-boyfriend would come.

"Kaichou, what are you doing?" Sona's queen, Tsubasa was worried seeing her king acted strange unlike her usual behaviour.

"Ah, Tsubasa. I don't realize you are here." That was the truth. Sona was too absorbed at the revelation that her idol would come visit.

"I've been here for the last 5 minutes, Kaichou."

Hearing Tsubasa's reply, she tried to calm herself. Adjusting her usual demeanor she told her queen to gather the rest of peerage and informed Rias and her peerage to come.

10 minutes later the rest of her peerage and Rias' were gathered inside Student Council office.

"Sona, why you are calling us here?" Rias expressed her concern to Sona after she heard from Tsubasa that Sona was acting strange.

"The reason i call all of you here is Elliot-Nii-sama will come for visit tommorow." Her word elicited surprise reaction from Rias and Akeno while both her and Rias' peerage confused.

"Nii-sama?" As far as Tsubasa know, Sona only have a sister, Serafall Leviathan.

"I forgot to tell you about him. Elliot-Nii-sama is my sister's boyfriend." Loud gasps came from everyone excluding Her, Rias and Akeno. After all Serafall Leviathan was one of Maou that governed over Devil, to think someone managed to charm her was preposterous. Then it dawned to them that this boyfriend probably worse than Serafall herself.

"Boyfriend, Kaichou? As in Magical-Girl/Maou Serafall Leviathan's Boyfriend. I do wonder what kind of man attracted to her." Her new pawn, Saji Genshiro blurted.

Sona glaring hole at Saji at the implication that Elliot had the same childish behaviour like her sister. "Normally i won't take any offense to that but since this is Nii-sama i think punishment is in order." She gave signal to Tsubasa to take a note to punish her pawn later.

"Speaking of El-sama, why sudden visit Sona?" Rias spoke.

"About that, apparently Nii-sama wants to learn as a teacher. Onee-sama said that Nii-sama is studying to become a teacher so Onee-sama suggesting that Nii-sama to come to Japan become a teacher in Kuoh Academy." Sona explained.

"I see. That's like normally El-sama doing." Rias laughed a little. She almost afraid if Elliot personally sent by Serafall and her brother to monitor both her and Sona. Elliot was a human but immortal as far as she knew. He lived far longer than the rest of her and Sona's peerage combine so his life was filled by doing various odd things that normally an immortal done in their spare time.

Sona nodded. Elliot was not an overbearing person like her sister if anything he was the opposite of her, a calm and intelectual person since most immortals developed strange personality the older they become. Sirzech and her sister with their sis-con or Azazel of Grigori and Odin the Allfather of Norse with their perversity. So she was more than glad Elliot came to visit and to learn as a teacher.

"What do you mean, Buchou?" Another pawn but from Rias' peerage, Issei Hyoudou, confused.

"Issei, El-sama is a human but he started dating Serafall-samma more than 200 years ago. So what it makes him?" Rias explained.

"I don't know." Issei answered sheepishly.

People inside the room other than Issei already knew the answer, 'Immortal'. But how, was something they couldn't explain.

Rias sighed at his cute pawn. "Issei, El-sama is an Immortal just like us but human."

Issei's eyes widened. "Seriously Buchou. I never know human can do that."

"Me neither. Just like most immortal do, El-sama is doing this to fill his time. Unlike someone i know(Sirzech and Serafall sneezed), El-sama fill his time wisely."

"I see." Issei was disappointed, he prefer someone cool more than Elliot. Everything that wise was boring. From what Rias said alone, Elliot probably an old-school-kind-of-guy.

Then Q&A sessions about Elliot continued with the rest of both peerage. After no more question from Issei and the rest of their peerage, Rias and Sona made plans about welcome party they were going to do.

(Elliot's POV)

It had been a week after Serafall came to visit me and today i was going to go to Japan per her request. She begged me to protect her little sister, Sona Sitri, a little girl i met when i accompanied Serafall in Devil Gathering 10 years ago.

Back then Sona was a very quiet girl which i found odd considering her hyperactive for a sister wearing Magical Girl costume everyday everywhere. But now, i didn't know what happened to that girl anymore aside few stories Serafall told me whenever she came to visit. Thankfully she didn't become like her sister which a headache on my part occasionally.

"Kyaa... so handsome..."

Right now i had more important things to do, namely running. Ever since i was transported to this universe, any female from various race will found me attractive. It couldn't be helped since my passive skill [Charm Species] making me attractive for any female under level 30 unless they were married or devoted to someone or a cause.

Since coming in this universe all my power undergo so many changes. It probably caused by God(s) and any mythical beings are real not a story like my universe where God(s) merely representation of a religion.

While i could disabled my passive skill but by doing so require effort which i had to consciously blocked said skill.

Teleporting also a no go either. Although i could wipe their memories of it, i prefer not to. I rather fighting Great Red and Ophis at the same time since it was easier.

Great Red and Ophis were a dragon with level Up to 85 and had Dungeon Boss status like most dungeon in Yggdrasil which making both equal to a monster with Level 95.

Fighting both of them didn't generate paper works so that's why i prefer fighting both than wiping memories. Thinking mountainous of paper in front of me enough to induce fear for anyone including me.

Focusing for my escape, i turned left, left, right and... hit someone when i about to turn right. Apparently i hit a male student from nearby academy and the student unconscious. There were only 2 academies in this town, Kuoh Academy and Private School of Homurada.

I had to act fast if i want myself out of jail so i healed him. The reason he unconscious was i hit him softly, if he didn't walk slowly it was like someone was thrown from a plane to ground without parachute twice.

5 minutes later he became conscious again, confused.

"Hello, young man. Sorry for earlier." I apologized.

The student raised a brow. "Huh?"

"What's wrong?"

"Are you a gangster?" the student deadpanned.

Bah, i forgot about all of the tattoos i had. I was covered by Tattoos from face to my arms that visible to everyone. At first when i created my avatar, i just wanted my avatar looked manly. Now i almost regretted it.

"Afraid not."

"Paedophile?"

I put my hand on my face at this. To be called as paedophile was a blow to my pride. Then again i date Serafall, a Maou with 5 times of my age. Well i could date someone older than her but most were not single.

"I just want to say, i'm sorry for running to you. I was in hurry." The student still looked blank. "Anyway, can i ask you where Kuoh Academy located?"

It seemed the boy recognized the name as his face changed from blank-with-hint-of-suspicion to a nod. "Follow me."

It took us 20 minutes to arrive.

"Here. This is Kuoh Academy."

"Thank you...?"

"Issei. Hyoudou Issei."

"Thank you, Hyoudou Issei. My name is Elliot, Elliot Scheeneider."

I didn't know why this young boy looked shock but i knew one thing. I will certainly enjoy my time in this place.
