Kurnugi settled in Harry's body and soul as he entered the Eclipse Gate. He had trained the ten year old for seven long years, all part of a plan to kill Acnologia so his mother's plans could continue.

Levy watched as a boy about her age walked into Fairy Tail. He was rather interesting, messy black hair and emerald green eyes hiding behind a pair of glasses. He was wearing a light eastern style robe (a yukata, she thought), dyed red, and had a red hilted saber at his hip. He approached Makarov as everyone stared at him, and said, in perfect Fiorian, "Hello, my name is Harry Potter. I would like to join Fairy Tail."

"I see," Makarov said, "and what magic do you use, my boy?"

"Sword Saint Dragon Slayer magic," Harry said, "It's easier to show than to describe."

"Then let's head on back and you can show us," Makarov said, hopping down from the bar and walking out back with Harry and much of the guild following behind him.

Harry shrugged off the top half of his robe, showing toned muscles for a ten year old and several scars across his upper body. Drawing the saber, he gripped it with both hands. He breathed in, then out and an aura of stillness seemed to form around him, suddenly, he snapped his eyes open and swung the saber through the air, a crescent of light following in its wake as he did, "Underworld Cycle!"

Rushing across the gap, he swung his sword up, "Underworld Purgatory Dance!"

Slashes etched themselves across the entirety of the training dummy. Harry sheathed his sword, just for a second, before drawing it, now on black fire, with a call of "Purgatorial Flame Slash!"

He jumped back cheeks bulging before he called out, "Sword Saint's Purgatorial Roar!"

The breath took the form of a vortex of black slashes that tore the dummy to pieces.

"Well, that certainly is an interesting magic," Makarov said, "let's get the stamp and make you a member of Fairy Tail."

Natsu looked up at the Guild, saying, "You really have another Dragon Slayer here, Gramps?"

"Yes, he joined a couple of weeks ago," Gramps opened the door, calling, "Harry!"

"Yes, Master?" a voice said from a table, sitting across from a blue haired girl reading a book was a dark haired boy wearing glasses, "Oh, by the way, Gray, you're stripping again."

"Gahh!" Another black haired boy in his underwear jumped up, "How long have you known, Harry?"

"Since you started," "Harry" laughed, "what did you need, Master?"

"This young man is thinking about joining the guild. He too claims to be raised by a Dragon, and was hoping you had any knowledge of where they went."

"Dunno," Harry shrugged, "Kurnugi flew us south one day and just… Disappeared. Not sure if he was done with me and headed back north or what. I wish I could help, but I can't."

"Oh," Natsu said, not even trying to hide his disappointment, before popping back up and saying, "well, if you see anything about Igneel, tell me!"

"Only if you promise to do the same with Kurnugi," Harry agreed.

Macao Conbolt sat in the carriage across from his temporary charge, who was hanging over the edge looking like he would vomit and second now, "Are you alright, Harry?"

"'S just a Dragon Slayer thing," Harry responded, "How long till we get to the job?"

"Just about another half an hour. I'll admit, I'm surprised you picked hunting monsters as your first mission. Most choose to go do delivery missions.

"Longer it's put off, longer people are in danger," Harry grunted, clearly using the least amount of words to get his point across as he fought his motion sickness. Macao had to concede that point, but still…

"Have you fought things before?"

"Kurnugi used to have me fight wild animals to get better."

"Well, Ok," Macao said, "I'll be there to support you if you get in over your head."

"Thanks," Harry grunted.

Harry walked through the forest, sniffing the air as they hunted their targets' lairs. Gripping Ereshkigal's sheath, he came across a cave. Macao said, "I'll be here if you need help."

"Thanks," Harry said, not admitting he was far too used to dangerous circumstances as he drew the sword made from one of Kurnugi's scales. The only gift his father had given him.

Out of the cave came a green wyvern, lunging at Harry, causing him to leap into the air as he gripped Ereshkigal with one hand, swinging it, "Underworld's Reaving Wind!"

A vacuum of wind slashed into the wyvern's neck, and Harry pulled back Ereshkigal, drawing it back while running a finger along the blade. Thrusting down, he called, "Purgatorial Piercer!"

The blade gave the illusion of extending, piercing through the wyvern's brain. Letting it collapse, Harry ran Ereshkigal across the crook of his elbow and sheathed it.

Sniffing the air, Harry continued along the cave until he found another, much larger wyvern. Drawing the sheathed sword, he caught the lunge on it, scraping back into a tree, his skin turning to black scales. Drawing the sword, he slashed it across the wyvern's eyes. As it opened it's mouth to roar in pain, Harry swung, calling, "Purgatorial Wind!"

The flurry of slashes went down the wyvern's throat and caused it to stumble back. Rushing forwards, he sheathed the sword, before drawing it just as quickly, "Underworld Purgatory Dance!"

The wyvern collapsed dead, slashes all across it's body.

Harry sat on his bed in Fairy Towers, the all boy's dorm for members of Fairy Tail. He was running an oil soaked rag across Ereshkigal. He wasn't used to the amount of people in the guild, him and Kurnugi had lived in isolation, only occasionally visited by Selene, the Moon Dragon God and Kurnugi's mother (which, Harry supposed, made her his grandmother), and even then, Kurnugi had been a harsh teacher.
