Illya walked in the guild hall of Fairy Tail. Like always, her fellow guild mates were in a brawl. She sometimes worried about the brain cells of her newfound family, all that fighting and drinking couldn't be healthy. But whenever those thoughts appeared, she would dismiss them. This land was in an Age of the Gods, where humans were strong and magic was plentiful. Magic of this world was basically aspects of the Root taking certain forms. Whether it is fire conceptually powerful against dragons of ice that is conceptually powerful against demons. The magic here was insanely strong, with the weakness being that once you belong to a particular school of magic, it is extremely difficult to learn another. That's why the wizards of this world will only use one magic. There are some who have two or more types of magic, but those schools are similar.
For instance, take one of Illya's best friends, Mirajane Strauss. Her magic from before was demonic Take Over magic, letting her absorb demons into her powers, transform into them, and use their powers. This power gives Mirajane a better control over transformation magic and because sleep and demonic powers both have an element of darkness connecting them, helps make Mirajane adept at sleeping magic. Illya's magecraft are different than this world's magic, making her very more versatile.
Speeking of Mirajane, Illya found her crushed under her brother, Elfman. One of the boys had thrown the giant of a man into the pin up model. Walking up to him, she grabbed the man and through him off Mira. Elfman was sent flying onto the ceiling, then crashing to the ground onto another mage, Nab. B ranked strength has its uses.
"Are you okay, Mira?" Illya asked, offering a hand.
"Yeah," the girl said. "I'm quite alright."
Suddenly, Illya heard a squeal behind her. Illya turned to see a pretty blond girl. She word a belt with keys and a whip on it.
"You're Illyasviel von Einzbern!" the blonde girl said. "You're one of my favorite Fairy Tail wizards! I'm your biggest fan. Sorcerer Weekly says that you're one of the most powerful wizards ever!"
Illya blinked at the praise. It was obvious this girl was a fangirl. The homunculus smiled. "You can call me Illya. Are you a new member?"
The blonde wizard gave a giant grin. "Yeah. I'm so glad to be in the same guild as someone like you. I'm Lucy, it's nice to meet you."
And with that, the blonde turned away to talk with Natsu Dragneel. Illya like Natsu, he was like the extremely stupid brother she never had. Well, she had Shirou, but after centuries of livings, he was technically the older sibling now. Seeing Natsu and the newbie talking together reminded her of her first day of Fairy Tail.
Flashback
Illya had followed the blonde boy, Laxus, and his grandfather. They went to their building, the guild hall of Fairy Tail. When they entered, everyone stopped chattering and looked at them. Illya nervously hid behind Laxus.
"Yo, Master," a guy with a man with a pompadour haircut and smoking a pipe said, "who's this?"
The little master smiled and brought her in front of him. "This is the new member of our family. We discovered her sleeping in the forest and the poor girl has no family. Her name is Illyasviel von Einzbern. Isn't she adorable.."
Blushing, Illya twirled and curtsied. "You all can call me Illya for short."
Everybody squealed and Illya thought she actually saw pink hearts in their eyes. "She's adorable!" they all cheered. "Welcome to our family, Illya!"
Illya stared at them. 'A family,' she thought. 'I have a family. I have a family. I have a family!' The girl began crying tears of joy. "Thank you," she said. "Thanks for this!"
Laxus hugged Illya. "Don't cry," he ordered. "You shouldn't be crying."
Illya smiled and wiped her eyes. "Okay."
"Looks like Laxus has a girlfriend," a man with spiky blue hair teased.
"Yeah, aren't you a player," the man with the pipe agreed.
Blushing, the two kids quickly moved away from each other. "He's/She's not my boyfriend/girlfriend," Illya and Laxus said simultaneously.
Master Makarov laughed. "Well, my children. "Welcome to Fairy Tail!"
End Flashback
Illya woke up in a daze. Remembering that fond memory always made her feel happy and accepted. It was the first instance when she finally felt at home. She looked up to realize that she had been daydreaming for a while. The sun was already setting.
"Oh, you're awake, Illya?" Mirajane asked.
Illya chuckled. "Yeah, I guess I've been thinking about something lately." She then smiled. "I'll be going home. Later, Mira!"
The homunculus girl waved goodbye to her friends and then left to go home.
