[Comprehensive HP] In the name of darkness

With the interference of Sirius' teaching and other incidents, Harry didn't know the progress of the gold cup until the beginning of school, and there was no clue about the crown hidden in the Room of Requirement. Although he learned a lot, everything was in the The standstill annoyed Harry.

"Remus, I heard you're going to teach at Hogwarts?" Harry sat on the floor of the empty classroom, eating chocolate. Lupine knew Harry's limits very well, and would give him chocolate when he was exhausted. .

"Well, Protection of Magical Creatures class." Lupine sat next to Harry, "Hasn't there been a lot of expulsions in the Forbidden Forest recently, and those creatures with nowhere to go have been classified as textbooks."

"Including the acromantula?" Harry turned to look at Lupine.

"Speaking of which, why did the population of acromantula disappear so quickly?" Lupine shook his head. "When Dumbledore went to visit, there were no acromantara in the Forbidden Forest. Hagrid was still sad these two days."

"It's not me." Harry shook his head, "My dad still wants the venom of the acromantula, and besides, do you know what spiders are most afraid of?"

"Snake." Lupine raised an eyebrow, "What do you mean?"

"Basilisk." Harry fell back, his back against the ground, wet and uncomfortable, but tired. "The basilisk has been gone for almost three months."

"You mean, the acromantula was eaten or driven away?" Lupine asked in surprise. He knew Harry and Slytherin's guardian relationship. Since the Forbidden Forest belongs to Slytherin, why did something happen to Harry? Don't know at all?

"I don't know." Harry smiled wryly, "They don't believe me." The unicorns and centaurs in the Forbidden Forest are intelligent species, and they don't want to rely on themselves as guardians, so what can they do.Anyway, no one would do anything to the animals in the Forbidden Forest now, so he was happy to be at leisure.

"Who?" Lupine responded. "You mean the leader population of the Forbidden Forest?"

"Hmm." Harry moaned, covering his head with his arm, "I'm not trusted~"

Lupine looked at Harry's small body, "Actually, you can change the way, such as playing with the cubs inside them, and then the cubs—hahahaha—"

"I'm good at silent spells. Professor." Harry squinted and smiled. He's not a little girl, what kind of situation is he with the cubs!

But Harry will soon know what black-bellied revenge is.

"I'm going to make some preparations for the next two days, just in time for you and Sirius to speed up the progress." Lupine said to Harry after the lecture. Protested several times, and when Harry learned him he could tell Sev that the black dog would suffer.

Harry thought about the recent progress, the corners of his mouth drooped, he mastered the method but could not completely transform, Sirius felt that Harry could not fully trust his own magic power, but a person who used himself as an experiment since childhood, most trusted in himself How can you not trust your own magic power?

"Maybe you don't need it yet." Draco looked at Harry, who was covered in hair but not deformed. "Your father and the others practiced because they needed to help Lupin."

"When do I need to use this?" Harry looked at the black hair on his hand. "Escape? If that's the case, I'd better learn to swim beforehand."

"Swimming helps you grow taller." Draco nodded, and then asked, "What will you become?"

"Maybe it's a cat. I don't think I'll turn into a black dog." Harry trembled, and all the black hair on his body was retracted. Those hairs were short and shiny, and very soft, not like a canine. rough.

"Could it be a kitten?" Draco looked at Harry, put his hand next to his head, "Meow~"

"Kitty?" Harry heard Draco's words, and the corners of his mouth twitched. If that was the case, he would never use an Animagus in his life.

"School is about to start, you should read your textbook first." Harry said as he walked into the bathroom. He has been very irritable recently, and he always felt that something would happen.

Draco pursed his lips, closed the book, put it on the table, and took out what his father gave him. I'm afraid even Voldemort didn't know this information back then. His father asked him to memorize it within three days, but Draco Ke was hesitating, maybe this information could be given to Harry.

"Malfoy." Draco touched the pattern on the parchment and said softly, "Malfoy."

Harry came out of the bathroom and looked at the person leaning on the head of the bed who seemed to be falling asleep, Malfoy.Pulling out the chair, when Harry was about to cast a spell, he saw Draco's ice blue eyes looking straight at him, "It's been three days, you have to sleep today."

Harry blinked, and Iggy was pawing at the parchment beside him, shaking his head, indicating that today's work was done.Harry raised his hand in surrender, then lay back on his bed, closed his eyes, and felt sleepy for a long time.

Draco put away the tip of his staff, leaned against the head of the bed, yawned lightly, and fell asleep on the bed.

In the middle of the night, Draco heard movement from Harry, and when he woke up rubbing his eyes, he saw a black lion lying on Harry's original position. "Merlin!"

Draco got up, and the lion's green eyes turned to look at him, there was still a little confusion and doubt in the eyes, but the eyes reflecting the moonlight revealed more bone-chilling coldness.

"Harry?" Draco stepped out of the bed and walked towards Harry, the lion nodded, stretched out its black claws, and smashed the bedpost directly.Yige flew down from the bed and honked twice.

"Recovery as before, zoom in quickly." Draco connected the two beds in the dormitory, and reinforced the feet of the bed, leaving room for the lion to move around.

"Why did you suddenly change?" Draco knelt on the bed, reaching out to touch the lion's mane, which looked a bit like the curls on Harry's head.Harry shook his head, a meow sound came out of his mouth, and then he shut up instantly.

Draco laughed and fell on the lion's belly when he heard Harry's cry, "It's still a big cat."

Harry rolled his eyes and tried to get his wand, but after two failed attempts, he simply wrote 'Nightmare, escape, transform' in the air with his paw. 'The lion's paws were not easy to control, and the written words were a little twisted. After making sure that Draco understood, Harry waved away the handwriting.

"In other words, you don't know how you got here?" Draco buried his face in Harry's black fur, so soft.

"Can you change back?" Draco rubbed his nose and buried his hands in the lion's fur.

Harry lay on the edge of the bed shaking his head, theoretically he understood, but now—he was a little subjective and didn't want to change back.And it changed so suddenly, he had to think about how to go back.

"Gryffindor." Draco muttered, not sure if he was referring to Harry's sudden transformation or Harry turned into a lion.Harry put his paw on Draco's head, covering his entire face.Draco kicked his feet and laughed, stepping on the lion's tail with his white and slender bare feet.

Harry turned over and laid Draco on his stomach, looking at him with blue eyes dissatisfied, 'You are happy to see me unlucky? '

"Why are you so unlucky?" Draco stretched out his hand to scratch the lion's chin. The lion's head was bigger than both of his hands. "You are thin and small, how come you are so big after transforming?"

'It should be related to the magic level. ’ Harry blinked, then wrote, ‘You look heavy, why are you so light? '

Draco pulled his lion's beard with both hands, "Are you saying I'm fat?!" Harry gritted his teeth, "Didn't you still say I'm skinny! '

"Hey, there's no bad breath." Draco was able to get in, and when Harry bared his teeth, his breath sprayed in front of him, and there was no strange smell.

Harry was speechless, opening his mouth to swallow Draco's head.

"Hahaha, Potter! Stinky Potter!" Draco smiled and stepped away, pushing the palm of Harry's canine.Harry drew back his front paws to hold him in place, obviously growing taller, Harry felt that Draco was still the soft little one he was when he was a child.

Draco pulled one of Harry's front paws, looked at the pad on it, "It's fine if you're always like this." Don't worry too many people find out that you're good, and also, it doesn't have to be so hard.

Harry turned his head, he would be crazy if he kept doing this, just thought Draco was joking, Harry stretched out his claws, and five sharp claws like crescent moon sickles appeared.Draco's fingertips touched the tip of a claw, and it was pierced with just one touch.

"Cut your nails." Draco protested, looking at the blood on his fingertips.Harry blinked, retracted his claws, hooked Draco's wrist and licked it, and the blood disappeared, "No cut. '

"Big cat." Draco lay on the lion's chest, covering the temperature on his face.

Harry smiled and wrote in the air with the tip of his claws 'I thought it was a leopard. '

"Leopards are big cats too." Draco looked up. "You're just a Gryffindor. Want to be something else?"

'Gryffindor is the golden lion, where is the black lion. 'Harry rolled over his paw and shook it in front of his face, it was black and shiny, but it was dark.

"Gryffindor Black." Draco smirked, turned over and slid down the lion's belly, and pulled a front paw to cover himself, "If your patron saint is also a lion, it will become the symbol of Gryffindor even more .”

Harry shook his head. He couldn't release the Patronus, so he didn't have to worry about that.If all his representatives are lions, it is estimated that those who work with him will start to consider retreating.Harry chuckled, but turned his head to find that Draco had fallen asleep, and you just watched the lion sleep like this?Are you still a Slytherin,

Harry didn't wake him up, and Draco was basically staying up late with him during this period, but he often fell silent when he was lying down.However, with his claws, the kid's waist is quite thin.

Early the next morning, Draco took the lion that hadn't transformed back to Professor McGonagall's office.Professor McGonagall called Sirius to give him a hard training, and then instructed Harry to transform back.

Harry regained his human form in a sports vest and shorts, and Sirius suddenly said, "Harry, you seem to have grown taller."

"Really?!" Harry looked at his hands and feet, as if they were.

"It's not fully recovered, it will be fine in half an hour. It took too long for your first transformation." Professor McGonagall looked at Harry dissatisfied, "If this is after school starts, I must deduct points from you .”

"Sorry, Professor." Harry stretched out his hand and scratched his head, and heard Sirius suddenly say, "Maybe it's because he's not wearing any clothes."

The corner of Harry's mouth twitched, and Draco turned around and grinned.
