Year1: Troll

"Harry! Don't go after the damn girl! You might get injured or die for attempting to save a damn mudblood!".

Obviously Draco wasn't too happy about Harry going to save someone that they barely know and himself barely caring about.

"... Stay safe."

Harry threw his bag on his back and started running towards the entry of the hall amidst all the traffic caused by panicking students. Draco stomped on the ground angrily but couldn't do much more other than informing the nearest prefect about the current situation.

After a few minutes of tracking scent, Harry finally arrived at the bathroom in first floor.

"...The troll should be inside." Thinks Harry, who drew out his Udachi that his father left him with from his space extended bag. Majority of his family's wealth was still safely stored in the family vault, but he was immediately attracted to the long and shiny blade that is longer than himself when he first visited Gringotts with his foster mother. A very nice blade indeed, but Harry didn't really uncover anything on the sword other than that it is nearly unbendable and ever sharp.

After 6 years of rigorous training, Harry Potter is one of the best duelist in Europe, but not many people other than his immediate foster family know that he is way more talented with a blade than with his wand. From the earliest memories that Harry remembered, besides the red splatter of blood that marks his parents' death, it was the shiny and ever changing reflection of a sword. He doesn't even know where it comes from, but he just knows how to position himself and wield the sword like he had been killing people since before he was born.

Harry didn't actually come here for Hermione, the poor mudblood girl that gets laughed at by Draco and even her own housemate Ron Weasley. He came here for a change to challenge himself and taste blood, even if it's not really human blood. He is a born killer, and he knew it better than anyone, even though his foster mother seem to think that it was because of her education. Pity, Harry thinks, she doesn't know that he never felt wrong or repulsed when he executes people and monsters alike.

He pushes open the door and the immediate stench assaulted Harry's nostrils. Bad smell, obviously a mountain troll then. 12 feet tall, extremely resistant skin to magic in all forms but only partial resistant to physical damage. It's time to test whether this blade can cut open the monster's head or he would lose and get smashed. He blasted up a sink with his wand to signal the mountain troll that his enemy has come for him.

The mountain troll turned around with blood shot eyes and an extremely big sword in its hand. Most trolls are not trained in martial arts, but obviously not this one.

"...Harry Potter. Nice to meet you." Harry said nonchalantly, and positioned his blade horizontally.

Ding! The mountain troll immediately charged forward but Harry was quicker and parried the first blow from the giant bastard sword.

Magic doesn't just reside in Wizard's wands and cores, it also resides in their body. By constantly exercising and some help from potions, wizards can have bodies with reflexes and power that exceed even the most vicious monsters. And that is why the greatest battle mages don't just use wands, because by the time most wizards aim and fire, the quicker mage would have already cut their heads off. Harry haven't used any potions or rituals to enhance his body like his foster parents, but his natural magic had already strengthen his body to the extent that he can block blows from monsters without frowning.

The mountain troll didn't just stop, it actually slashed right back at Harry who jumped up to avoid the second blow. With a push from his magic and leg, Harry jumped over the troll's head and kicked viciously at it, knocking it over to the nearest stall.

"Arrrrgh!" The mountain troll was enraged and immediately started wielding his giant blade around. This time Harry parried the first one but squatted down to escape the second one. By the time the mountain troll re-established its balance, Harry has already fired a slippery spell at the floor.

The troll charged forward but was tripped up by the suddenly appearing oil on the floor, and Harry did not miss the chance. He sidestepped the troll and slashed a huge cut to the arm and chest region of the troll. Green blood immediately splashed out of the wound.

A few more parries and clashes of swords later, Harry finally found the opportunity to finish the killing blow. He jumped over from the sink near him and used the wall to speed up his kick. Jumping onto the back of the troll, Harry raised his sword and concentrated all his magic onto his arms.

Swish! With the enhanced strength, the sword cut into the neck of the troll like hot iron cutting through butter. But it was still too little a damage to actually finish off the troll. Harry decided to jump off the troll and use the sword's cut into the neck as a pivot, and the rotation of the sword finally cut off the troll's head cleanly.

Putting back his blade into its sheath, Harry finally noticed that Hermione was hiding beneath a nearby destroyed toilet seat and gaping at his "heroic" actions.

"...See you around." Harry put his bag on his back and walked out of the toilet. He better get away from here before the professors come around and see a giant troll splattering blood everywhere. Not the most sanitary scene.

"Explain yourself, , what have you done with the troll?" Snape arrived at the right time. Well, there goes a few days of rest for Harry...
