Issei and his sister entered assembly hall, and they took their seats. Vivio in first class sector on the right side of the room and Issei in second class sector on minutes later most of the seats were already occupied, the light went off and chairman of the student council entered the stage. Students greet her with applause.. She checked microphone and she began.

"Thank you" she said and when the applause died down she went on "My name is Souna Shitori and as chairman of students council, I have the great honor and pleasure to welcome you all at the start of the new academic year in Kuoh academy. hope that your stay in our school will be fruitful in new friendships and experience and and each year you will be eager to return to it. I remind the clubs begin to function from tomorrow." she ended her speach and left with big applause

'She must be popular' he thought and left room like others did. When he was on the way to class he had heard that girls talked about 'perverted duo' and how little luck must had their classmates to be with them. He entered class and saw that he had only two male classmates and Issei cursed his luck, they was 'perverted duo'! And what more he had to took seat near them. Issei wanted to cry!

"Hey new guy!" said baldy, his name was Matsuda or something like that.

"What?" replied Issei

"Hey, isn't he a new guy?" "Why is he talking with perverted duo?" "Don't tell me that we have another pervert!" "Iie! Please don't tell me that perverted trio is born!" he heard girls' whispers in class.

"Did you know about the greatest treasure in the world?" said this one with glasses, his name was Motohama?

"I don't know and i propably want to know. Do you really have to tell me?" asked Issei, he really didn't want to know about their 'the greatest treasure' but they didn't listen to him

"Oppai of course!" said both together. Really? Their 'the gratest treasure' was tits? "And we perverted duo ask you to join us to peep girls today after this lesson" said Motohana

"Ah! He is lost!" said one of girls. Really? Did they loudly told about peeping? They weren't just perverts, they were idiots. Wait a moment did his sister doesn't have PE after this lesson? He has to make sure.

"Guys, you do not want to peep the first class, right?"

"What a question it is? Of course we want. I heard that one of the new girls have a great body! Her name was Vivio or something like that" said Matsuda and then everyone felt killing intent.

How did they dare?! They offered him peeped his sister! "How do you dare!" yelled pissed Issei

"What you mean" duo asked terrified

"Oh, so you didn't know?" said girl with brown hair and glasses

"Knew what?" asked duo

"Vivio Takamachi Harlaown is imotou of our new classmate Issei Takamachi Harlaown. And you just pissed overprotective older brother. Don't worry I will be on your funeral" said girl with grin on her face

"If I will find that you peeped my sister, your punishment will be painful! DID I MAKE MYSELF CLEAR?!" Issei threatened them and the rest of the class started screaming with joy. Not only their new classmate didn't want to join to perverted duo, he threatened them and he looked good! Maybe they have new prince of Kuoh or even king!

"H-hai!" perverted duo only responded

Few second later class teacher came in and class has started.


When class has ended Issei noticed that perverted duo disappeard.

'I hope they aren't that stupid.' he thought and sighted 'Who am I kidding? Of course the are! And i hope Vivio not find them before me or she will befriend them in our mom's style' Don't get him wrong, he didn't care about them but Earth still was Non-administrated world #97 and showing magic to mundane people was still prohibited and using Starlight Breaker or Divine Buster didn't help in hiding magic, not even mention the devastation.

When he was near gym he saw duo while peeping, he sighted and look around if someone saw him, he didn't noticed anyone.

Ddraig|

|[Yes?]|

|Barrier please but small one|

[Gefängnis der Magie] Ddraig said in belkan, under Issei appeard green magic triangle and small barrier set up, only for Issei and two perverts.

"What the hell!" yelled duo when they noticed barrier

"Ddraig! Set up!" said Issei

[Stand by, ready! Set up!] only replied his device and moment later with flash of green light Issei was in his barrier jacket. It was massive blue metal boots, long blue trousers. Black formal shirt with gold buttons and red long coat.

[Handschuheform] said Ddraig and on Isseis hands appeard massive red metal gauntlets with green gem

"I-issei? Mate? What is g-going on? W-what is this outfit" said Matsuda with terror in his voice

"You are really stupid duo. You did three big mistakes First. you loudly told about peeping. Second you said to older brother about peeping his sister and third, depite threat you peeped his sister. So what older brother should do?" said Issei with cold and they begin run. After few seconds later they hit barrier. "Did you really think that you can run from me? Are you ready for your punishment?! Ddraig! Load cardridge!"

[Explosion! Raketeform!] his device said and two small jet enigines appeard on his gauntlets.

"Raketen..." He yelled, engines turn on. He disappeard and appeard near them. "...Schlag!" He yelled and he hit them with full power. He beated them for few minutes with full power and when they almost fainted he stoped and deactivated his barrier jacket and barrier

|Vivio-chan| he said telepathically to his sister

|Yes Onii-chan?| She replied

|Two perverts are peeping you| he said and heard his sister's voice from gym

"Iie! Someone peeped us!." And minute or two later pissed girls ran out gym and noticed him and perverted duo

"I punished them but i don't think that anybody will care if you will punish them again. Bye girls!" he said and walked away hearing perverted duo's yells again. Only one small whitehaired girl not beated duo but stared on him. Less than hour later Issei was called 'King of Kuoh' by girls and 'enemy of men' by perverted duo, rest of male populations of Kuoh academy didn't care too much about him. Duo also tried to tell about strange Issei's transformation and magic but nobody trust them.


It was boring math lesson. Not that Issei didn't like math, but because his magic was based on math and every device was basically a super calculator highshool math was too easy to him, so he decided to use this time for a talk with Ddraig

|Ddraig|

|Yes?|

|How about devils or other supernatural being? You found something?|

|[Well, it looks like this school have strong wards what make it impossible to detect who is devil, but i am sure that devils are here]|

|Well we have time, i didn't expect that we find anything already on the first day|


Seven hours later

Issei was coming back from school and thought 'My God! i never thought that beating these two perverts give me so popularity. soon they will invite me out on dates just because i am popular'

"Etto… Excuse me!" he heard girlish girl from his back

'Don't tell me that i was right' He thought and sighted "Yes? How can i help you?" he replied and turned

"You are Issei Hyoudou-san right? Or am I wrong?"

'Hyoudou? Last time I used it was nine years ago. How does she know my old name? Do i know her? And these uniform, i don't recognise it.' "Well, maybe I am" he only replied |Ddaig. What is she?|

|[You notice it? Well she is propably fallen angel.]|

"Etto… I am Amano Yuma and I just want ask you something. Are you see anyone right now?" she asked

"Now? No, nobody but.."

"Its wanderfull"

"Wonderfull?"

"I mean if you are single maybe will you out with me?"

|[She want to be your girlfriend? Beware, aibou, she plot something]|

|I know it Ddraig but i am spy after all. Maybe, thank to her, I will contact this Azazel. If she will try somethin will just arrest her.| "What do you mean?" he petend to be suprised

"Do you want be my boyfriend?"

"Of course, why not? We can try"

"I am so happy!" she run to him and kiss him in lips " We will se tomorrow my Issei-kun" she told to him and she run away

"Well, she is fast. So 'Heaven's Evening Daze', huh?" he told to himself and went to home


Next morning she waited for him before his home

"Oh Yuuma-chan? How you know that where i live?" he asked interested

"Well, i saw you sometimes when i went to school last year. My school is few minutes closer than your so we can go a bit together. If you don't mind of course"

'She isn't a good liar' "I would love it" he replied with fake smile

Well even if Amano Yuuma was a lie and he knew it, he blessed his luck. Thank to her girls didn't even begin tormenting him with requests to dating so school days was peacefully, only sometimes perveted duo asked him for beating because they tried to peep his sister, really these guys didn't has self preservation instinct.


Friday came. Issei and Yuuma went from school, they was near Issei house when Youuma asked..

"Nee, Issei-kun?"

"Yes Yuuma-chan?"

"It was five days since we are together, right?"

"Yes, you asked me at monday. Why you ask?

"So maybe we will go to real date?"

"Sure, why not? When and where?"

"I can't tomorrow, my mother wanted help with something, so maybe sunday, ten o'clock, in mall."

"I didn't have any plans for sunday so sure"

"So sunday then. Night Issei-kun, I am very happy that you are my boyfriend" she said, kissed him in lips and ran to her home"

"Night Yuuma-chan" he said to her and entered his home

The whole conversation was heard and seen by a small white-haired girl, she didin't know that Issei was aware about her

|Ddraig, are you sure that she isn't problem?|

|[Don't worry aibour, in contrast to the fallen angel, the devil is not a threat. She isn't aware anything about you. Her king propably want know what fallen angel doing here. Kuoh is devils' teritorry after all]|

|I hope you are right Ddraig|


Sunday, date's day came. It was quarter to ten when Issei reached the place.

'I hope she won't be late. After all it was her idea' he thought the he heard

"Here, take a flyer!" and strange woman give him a flyer with small magic circle, that wasn't mid-childan, and with 'Your wish will be granted' writted on this. Woman only gigled and walk away. People who wasn't aware of magic could think that woman was cosplayer or that she worked in coplay cafe but Issei knew that she was a familliar.

|Draig|

|[Yes?]|

|I have bad feeling about this date. Waageform without barrier jacket|

|[Waageform!]|

Waageform was a defensive form of his device. After he activated this form red dragonlike scales appeared on his skin. Normally they were hidden under clothes so he could use this form among people who didn't know about magic.

"Ah Issei-kun." he heard his 'girlfriend's' voice and he put flyer to his pocket

"Hey Yuuma-chan!" he replied and turned to her

"Sorry for keep you wainting"

"Don't worry, I've scarcely come here." 'So let's the date begin.'

Even if this date was a farce, make her has fun this time was his prioritty, after all he didn't plan be single forever, if Yuuma will has fun his future real girlfriend will has too. Well he had little experience at making girl to have fun, he sometimes took his sister to the city and she never complain. Of course his sister was very childlish and it was on mid-childa but women do not differ so apart. The first point on the plan of the day was the cinema. He chose a romantic comedy. Good one if he should believe to what he heard from sisters and mothers. When movie was ended he knew one thing, romantic comedy wasn't genre for him but Yuuma had fun and it was more important. Second point on plan was something to eat. He knew ideal place. It was small restaurant but with very good dishes. They both ordered pizza's. Issei took one with chiken, beef, lamb, salami and hot peppers and Yuuma took havaiian. When they had eaten, Issei took her to the desert to a nearby ice cream shop. Issei took strawberry coctail and Yuuma ice cream dessert. After that the went to shopping, they buy only few things but they had a great time. It was evening when Yuuma took Issei to park.

"Issei-kun, I really have fun today" she told but Issei heard sorrow in her voice

"You are right, it was fun Yuuma-chan"

She stopped and kissed him in lips then he felt that she set barrier, really weak one, someone who wasn't aware of magic could never noticed it, even if he was inside. After kissed she walked to fountain that was on middle of the park

"There is something I want to do to celebrate our first date. Can you listen to my wish?" she said still has that sorrow in her voice

"Of course"

"Will you die for me?" she said and where moment before standed human girl named Amano Yuuma now standed fallen angel woman. In her hand she had red light spear

"So it was your plan from beginning or my date was mistake?"

"Your date was great but i have orders. I have to kill you now before you will awaken your sacred gear" she said with grief in her voice and throw light spear in Issei. "You was a great man Issei Hyoudou, good bye" she said and turned

[Panzerschild!] she heard and turned back, she saw that her target was not only unhurted but before him was strange green magic triangle

"You are too late. I awaken my boosted gear long time ago. Ddraig! Barrier jacket set up! Schwerform! Barrier!" he said and moment later he was in his barrier jacket and have one gauntlet on his right hand. It looked like boosted gear but was bigger and more massive

[Schwerform! Gefängnis der Magie!] after this word magic barier was set up

"Amano Yuuma, if that really is your real name, you are under arest for atack on Time-Space Administration Bureu's mage. This barrier not let you left untill i let you or untill you kill me. Surrender or I will use force"

[Boost!]

"I can't fail Azazel!"

"As you wish. Divine shooter!" two green balls appeared near to Issei "Shoot!" after this command they shot in Yuuma. She tried lost they by flying but balls chased her no matter what maneuvers she did in the air

[Boost!]

One ball hit her. She didn't remeber how long ago human give her much damage as one of these balls

[Boost!]

"Amano Yuuma. It is you last it you last chance!"

"Never!" in moment when she said that in front of Issei appeard big green ball of energy

"Divine Buster!" [Divine Buster] Issei and Ddraig said together and at the same moment big green beam shot in her. And she fall stunned.

"So I befriended my first girlfriend... I am really son of white devil." said Issei to himself, binded her by chain bind and deactivate barrier


|Kaa-san!|

|Yes Issei? How was your date?|

|Date was good but my girlfriend supposed to be fallen angel and she wanted kill me so i befriend her in your style...|

|Oh Issei, I am so proud|

|Mom, please! I need someone to take her|

|I will be there with Hayate. Where are you?|

|Park with fountain, you know where it is right?|

|I know, we will be there in second|

Second later Nanoha and Hayate appeard before Issei

"So it's her?"

"Hai kaa-san. What will we do with her."

"Well, she tried to kill you, Issei-kun, and she didn't want to surender so i take her to prison on Mid-childa. I will interrogate her, i will tell you when she will begin talk" Hayate sighed and teleported with prisoner.

Nanoha and Issei decised didn't use magic to go home


Ocult Research Club

"So she killed him" said disapointed blackhaired girl

"Sadly, yes." replied her king

"Didn't your familliar give him our flyer?" asked amazed girl

"She did, flyer wasn't destroyed but somehow his wish didn't activate it" replied depresed Rias

"So when will you tell his parents?"

"Now" she said, she standed in midle of gremory magical circle and disappeared


In next chapter Issei will meet Rias and her peerage and Raynare will talk


A/N Rias won't be bitch who wanted Issei's death only to reincarnate him as a loyal pawn

Raynare used his old surname because she found only that, she (or Azazel) couldn't found any informations about him, after all he disappeard after his parents funeral
