Yo Minna! Konnichi wa! X) I made another fan fiction AND this time, it's a crossover "The World God Only Knows X Zero no Tsukaima". It's my first crossover fan fiction, so I hope you'll like it. 8) Btw, in the summoning speech, I am just getting words from what I have learned from my German friend. I don't know if I used the correct words in the summoning speech. X))

Chapter 1: The Summon and the Teleportation

"Wahahahaha! I can already see the ending!" In a spacious classroom where students are in to listen to the teacher's discussions, a boy with hazel-brown eyes and bed hair and with eyeglasses, suddenly laugh like a hyena upon playing his PFP. All students inside the classroom looked at him in disgust for his actions, interests and characteristics surpass a normal human.

"*smile* Ka-tsu-ra-gi, if you want to play, then…GO PLAY OUTSIDE YOU IDIOT!" Kodama, Katsuragi's English teacher, threw him outside the classroom immediately with a raging face. This kind of situation is not new for the old students who already knew the weirdest human in the city…or even in the whole world, Katsuragi Keima who is also known as the "God of Conquest" who can capture any girls he wanted.

Again and again, he always receives violent acts from the real world because of his love for the 2-D World? Why? Is it bad to love 2-D and hate reality? (-.-) "God Only Knows". Not even worrying of his grades, he immediately went to the rooftop where he believed that it's one of the places where he could play his games peacefully without any disturbance from the real world.

"Criiing! Criiing!" The last bell in the morning rang, emphasizing that it's already time for the next subject, lunch time. Elsie de Lute Irma, his useless buddy and his fake sister, run immediately to the rooftop for she's already aware that her nerd partner and beloved Kami-Nii-sama is playing. Even though she's his useless partner and not his real sister, she's still one of the people who understand Katsuragi well.

Upon opening the door to the rooftop, her smile widens upon walking her way to his exalted brother. There in a bench, Katsuragi still kept on playing, pretending that his dumb partner didn't exist. In his life, she is one of the most annoying people that exist, but despite of her, being his fake sister, he still cares for her for he treated Elsie one of his family…a little.

"Hai~ Kami-Nii-sama, I made this for you so eat up. (^_^)" Elsie handed the bento that she made it first thing in the morning just for her exalted brother. That's how Elsie cared and loved her "god-like" brother for she even made him a bento that was made very early in the morning despite being his useless partner and fake sister.

Looking in disgust, he turned his way away from Elsie's bento as if it's a poisonous one. Well, it's not really poisonous, it's just…uhm…some kind of a food that's not meant to be eaten by humans like him. Elsie is a demon that lived in the hell for about 300 years. She's still not used in using normal ingredients for cooking that humans usually used, so she just used hellian ingredients for she is already a high rated cook when it comes to this.

"Come on Kami-Nii-sama~ you must at least fill your stomach." Elsie insisted while tying Katsuragi with her raiment so that he won't run away. Who wouldn't run away if somebody would see a gigantic squid that's still moving in a bento box?

"Waaaah! S-stop it you bug demon! Don't feed me with that thing that could damage one's body!" Katsuragi tried to get away, but it seemed to be useless for he's tied up with Elsie's raiment. Slowly, Elsie opened his mouth while trying to put the food in his mouth.

"*chew* hmm, not bad." He said upon chewing the food in his mouth. Its kind a bit tiring to chew for it's too hard to chew for a human like him, but it tastes good.

"See? I'm really good at my cooking skills ne, Kami-Nii-sama?" She said in a chibi way upon smiling like a kid.

"Not bad…for a demon (-.-)." He just looked away with a slight nod upon playing his game continuously. Elsie pouted upon punching his head countless times.

"Mou~ Kami-Nii-sama, why are you so mean to me?" She continued punching him countless times like a punching bag while Katsuragi is suffering from her violent action. Well, he's already used to this kind of abuse for almost all people he knew were acting like this. Examples of those people are the goddess and the goddess hosts. They just act the way they wanted without my permission! Urgh! What did I do to receive this kind of abuse?! (-.-)

-Tristain 7:20 a.m. -

"WHAT ARE YOU DOING, YOU PERVERT?!"

"W-wait a minute L-Louise. I-it's a m-misunderstanding. P-please stop that-Waaaah!"

BOOM!

A usual noise that can be heard in the city of Tristain, where it's one of the cities where mages existed…and in fact, the world itself is a place for mages. No humans existed in this unnamed world and if it has, then they were treated as slaves…but there's a certain human that was treated like a noble for he, himself, is a normal human like other humans, but because of a summon ritual, he was sent to that world where commoners were treated a slaves or helpers.

That man's name is Hiraga Saito. He was summoned by a female mage who was believed to have "zero" type mage. That girl's name is Louise Francoise Valliere de la Baume le Blanc de la Valliere. Together, they made lots of achievements that made the princess and the people of Tristain proud. Because of this, everyone treated Louise equally, unlike before that she's bullied because of what they believed that she is a "zero" type mage.

Until now, they still serve the city of Tristain especially when there's a war against the other cities. They are one of the best partners and one of the best love team…but they're also one of the love teams who have most numbers of Love Quarrels in a single day. (-.-)

"*sigh* It's them again." A gray bearded old man said while sighing. He didn't see the two lovers quarrel with each other, he is just certain that they are the one who were having an LQ because…it's already part of their daily routine that anybody would hear something like that, they didn't need to see who's quarreling for they are already certain that they were the one who's having an LQ. (-.-)

"A-a-a-" Paralyzed, Saito Hiraga is in deep pain after the explosion that's been produced by Louise through her wand.

"Hmph! A pervert man like you should be punished! I'll lock you up here so that you won't be able to peek to another girl's skirt!" Louise blew her wand gently before she dragged Saito to a cage that she made just for her familiar (Saito) to stay in case he'll do some perverted acts.

"I'll just imprison you in here just for an hour. If you won't change your behavior on doing perverted things, then…*grabs a whip upon laughing ominously*"

"A-a-a-a!" Saito is still half unconscious because of the explosion.

"Hmph! I'll go now!" A little upset, she turned around and walked out of the room before she slammed the door.

Upon walking through the hallway, Louise's facial expression is very visible where if one could see it, he or she'll back off because of her threatening aura. Thinking of a way to at least stop his perversion, Louise was able to think of something.

"Hmm, I'm sure that Saito's perversion will activate again, so I have no choice but to…summon another familiar again to watch over him incase he'll do something perverted." Her threatening aura is still visible, but this time it's already mixed with a smirk on her face.

-Meanwhile in Maijima-

"Kami-Nii-sama, please wait for me." Elsie tries to catch up with her brother, who is striding along the road with his eyes on his PFP. It's amazing to see someone who can stride while playing a game. Most people would bump unto someone if they did this, but not for Katsuragi for he's already used to this kind of routine where he didn't even need information in the real world for he can get information in the game world.

When Katsuragi and Elsie arrived at their house, Keima almost dropped his PFP because of his surprise. Who wouldn't be surprised if one could see six girls visiting him altogether like they are suitors if their genders were just reversed. Upon seeing them, Elsie's smiled widely upon wearing her apron, ready to serve her brand new costumers, the Goddess Hosts. It seems like mother is still out in the grocery to buy ingredients for the menu in the Café Granpa.

"Waaah~ it's very rare to see you all together, Ojosama. What do you like? Green tea? Red tea? ^_^" Keima's dumb buddy, Elsie, interacted the goddess hosts like their tension is already over after the second capture of the girls…but why is there a hollow in each one of them?

"Thanks Elsie-chan, but we're just here because we have some important matters to Katsuragi." Diana, Tenri's goddess, immediately responded before she looked at the frail boy who seemed to be annoyed of their existence.

"What do you want this time?! Can't you at least let me play my games?! I've been suffering for one week without even touching my PFP because of the search of the goddess! And now don't tell me that I'll have a new mission this time!" He said angrily while making a monstrous face. Who wouldn't be angry if the reality tried to separate a hard core gamer like Keima Katsuragi to his game world?

"Yes. You have said it." Vulcan, Tsukiyo's goddess, responded upon making a serious-looking face. The atmosphere

Keima: …

Goddesses: …

Keima: …

Goddesses: …

"… *chibi* Please excuse me. I think Yokkyun is calling for me upstairs." Keima was about to dashed upstairs towards his game chair, but the goddesses stopped him by pulling his collar. Of course, Keima almost coughed hardly because of their actions. (-.-)

"Yui's husband, this is an important matter so we hope that you'll cooperate with us. *draws nearer to him* don't worry~ you'll receive rewards from Yui later." Mars, Yui Goidou's goddess, seduced Keima like she usually did for she believed that by doing that, he will fall in love with Yui, but for a person like Keima, that's just merely a belief.

Struck by her words, all the goddesses except Mercury for she didn't care of trivial things, looked at both of them with threatening looks as if they are going to kill him anytime. Keima tried to get out of her temptations, but he seemed to be paralyzed for he is weak when it comes to aggressive girls. Looking at them ominously, the goddesses immediately took their attention by shouting at them loudly. Thanks to them, Keima was able to escape from Mars' advances.

There was a moment of silence before Diana spoke up upon looking at him with his cold-red eyes.

"Katsuragi-san, our main purpose why we are all gathered here is that you have something to accomplish that neither the deities nor the devils could ever accomplish it." She said, dead serious like her usual way of saying especially when it comes to crucial matters.

"…but first, we must bring you to that place where only us could do it." Vulcan added while saying it in a dead serious way.

...

"*sigh* I must be dreaming. I think I'll just wait a couple of minutes before I'll wake up." He said while playing his games dead seriously as well.

"…Katsuragi-san, this is a very important matter. Please take it seriously." Diana complained of his flippant actions.

"WHY WOULD I DO THAT? WHAT AM I? DORAEMON?" He exclaimed for he thinks that the real world is trying to detach him from his game world again. Without wasting any time, the goddesses did their ritual in summoning Katsuragi to the place where they wanted him to stay temporarily. Realizing that they are not really jesting, he widened his eyes in surprised when he, together with the goddesses, were already surrounded with a magical circle.

"O-oy! What is this…really all about?" He said while observing the magical circle at the same time. While making the ritual, Apollo responded in a serious way upon looking at the frail boy with her pink-colored eyes.

"We will send you to a place where mages exists. Only the mages, the deities and the high-ranked devils can summon or teleport someone there, but the summoning is only limited and it's only about 10% successful, that's why we must make the ritual perfect for to go there." She said upon doing the ritual together with her sisters.

-Meanwhile in the Tristain-

"Tsk! Why must I deserve all this?" Saito, who is imprison in a human cage that was made by Louise, is struggling to get out of it. Reminiscing of his past perverted behavior, he just sat down calmly while resting his head on the human cage.

"*sigh* to begin with, it's my entire fault. If I love Louise, then I should stop these perverted actions to prevent her of being jealous…but I just can't resist to see Tiffania's big b-boobs.*drooling*" Reminiscing of the event just a few minutes ago, he smiled in a perverted way. Well, he may be a pervert but he, Saito Hiraga, still loves Louise for he even died in a war just for her, but luckily he was saved by a fairy whose name is Tiffania. If not for her, he wouldn't be there anymore to look at their big boobs…I mean; he wouldn't be there together with Louise. While he was reminiscing the past of his perverted actions, he didn't know that Louise is doing something indictable against him.

In the secret garden of Tristain where she rechecked the materials needed for the summoning.

"Let's see now, first I must get this…and this. Hmm, Ahh! Perfect! *laughs ominously* Now I could do the summoning and once I will summon a dragon or a salamander or even an Anaconda *laughs* then I wouldn't worry about Saito of his perversion anymore." She said devilishly while starting the summoning. Summoning without the permission of the authorities is prohibited, but for the sake of Saito, she did this hideously.

"Mein unubertroffen aufdringlich, bitte sehr erscheinen auf vorderseite aus Mich!" She began the summoning without even thinking of quitting her plans. She didn't know the consequence of her actions of doing the summoning without permission of the authorities.

-Meanwhile in Maijima-

"WHY DO I NEED TO GO THERE?! IF YOU WANT A FREAKIN SOMEONE TO GO, THEN DO IT TO SOMEBODY ELSE! NOT ME!" He said irritatingly with an obvious irritated expression. The goddesses expect this respond from him for they just continued the ritual like they didn't heard anything. Before he was teleported, Minerva answered his question with a serious yet with a mixture of anxiety.

"It's because you're the only one who could do this, Keima-kun. You've got to save a number of girls in that world for they are also possessed by some Weiss. The rest is all up to you to discover it." That's the last word he got from the goddess before he was teleported…but before that, they grabbed Elsie, his buddy, so that she could be able to capture the Weiss when it will be out of a girl's heart.

He couldn't do anything from that time for he believed that the goddesses don't have any plans on stopping the ritual from the very start. All he could do is just go with the flow even though he doesn't have any idea of what's going on. All he just remembered is that he just needed to save a number of girls from the Weiss.

-Meanwhile in Tristain-

BOOM!

"*cough* what's wrong this magic?! Why won't it work?" The pink- colored hair girl pats her body for it's filled with dust because of the explosion. Well, everybody knew that Louise failed most of the time when it comes to magic. That's why she was named as "Zero Louise" because of her carelessness but it all changed when Saito entered in her life. She began to receive some awards from the royal highness.

She was about to retry the summoning again when suddenly she saw a figure behind the smoke. She waited for a few seconds for the smoke to fade away before she went near to the unknown figure. To her surprise, she saw a man with a pair of hazel-brown eyes, brown colored hair, eyeglasses and a foreign object that he's holding (PFP). Just like what happened when she summoned her first familiar, Saito, another commoner lying down on the ground.

Louise watched him getting up slowly upon caressing his head.

"W-where am I?" He mumbled upon looking around. He doesn't seem to be surprised to see a mage for he didn't know that she is a mage. Not until…

"So, you must be my new summoned familiar. Welcome to the world of mages." Upon drawing near, she said while observing him.

"Huh?" That's all he could say for now for he doesn't have any slightest clue of the event that the real world set for him.
