What Kasen meant:- The Dog has 3 Heads. It can easily eat 3 people. It will then split the 4th person so that each head has its share.

Upon waking up to a new day, Kasenhis groggily climbed out of bed.
Yesterday, thanks to the antics of four mischievous Gryffindor students, his planned alchemy experiment had been shelved.
Well, "mischievous" wasn't quite the right word—perhaps "brainless" would be more accurate.
And what was Dumbledore even thinking that day? Letting Hagrid use such a massive three-headed dog as a security measure? Truly baffling.
Still stewing in frustration, Kasenhis made his way to the Great Hall and sat down for breakfast. As he stared at the dry, distinctly English fare on his plate, he felt a wave of resignation. So this is life, huh?
After finishing his meal, Kasenhis didn't return to his office. Instead, he headed straight for the Forbidden Forest. He had a plan: find a test subject. After all, he couldn't just impulsively decide to stitch an Ender Pearl into his flesh—that wasn't experimentation, that was suicide.
On the way, he bumped into Hagrid, who was out with his dog—or rather, his hound, whom he called Fang.
Naturally, Hagrid was curious.
"Goin' into the forest, Professor Kasen? What's it for?"
"I need to conduct an alchemical experiment. I'll need some live test subjects."
Hagrid instinctively tilted his head back to look at the sky, as though silently seeking divine guidance.
"Test subjects? How 'bout a chicken?"
"It probably won't work," Kasenhis said, shaking his head. "We wizards have magic, right? So technically, the test subjects also need to have magic."
"Ah, gotcha. Well, this all sounds too complicated for me… best of luck, then."
Hagrid scratched his head, already overwhelmed by the mention of anything remotely technical. Wanting to save himself from further brain strain, he hastily tugged Fang along, putting some distance between himself and Kasenhis.
"Hey! Why are you running off? I wasn't finished talking yet!" Kasenhis called after him.
Hagrid quickened his pace. "No, no! I've had enough, thank you! You sound just like... my old Charms professor from when I was a student. Terrifying! Absolutely terrifying!"
"Alright then! May you dream of that professor every night!"
Kasenhis shouted in mock blessing.
In the distance, Hagrid stumbled slightly as he hurried away.
That afternoon, Kasenhis combed through the outskirts of the Forbidden Forest, rounding up a variety of magical creatures and locking them in separate cages. By the time he was done, he could safely call it a productive day.
As for what kinds of creatures he'd caught? Well, he wasn't entirely sure himself. His method was simple: wander around the forest, spot a magical beast, then toss an Ender Pearl to teleport next to it and take a solid swing at it.
For the larger creatures, he employed a different tactic—whacking them with obsidian blocks. If one hit didn't do the job, a second one usually did.
Dragging a chain of cages behind him, Kasenhis returned to his office under the bewildered stares of passing students, who couldn't help but give him strange looks. Once inside, he carefully lined up the cages in the corner of the room, ensuring all the creatures had food and water before leaving them be.
Then, he summoned an Enchanting Table, placed an Ender Pearl into it, and began the process. Before long, a glowing Ender Pearl infused with shimmering purple light emerged, resting neatly in his hand.
Then he pulled out a grindstone, placed the enchanted pearl on it, and started cranking. Each rotation of the grindstone caused a series of symbols to emerge.
Some were the glowing purple enchantment runes, while others were the natural markings of the Ender Pearl. This continued until—crack!—the sound of shattering echoed through the office.
"Ahhhhhhh!" [A scream that sounded eerily like Tom Riddle himself.]
"Hey! What's going on in here? That's one intense scream—what did you do to yourself?"
Professor Sprout, who had been walking down the corridor, froze at the terrifying noise coming from Kasenhis' office. She debated for a mere two and a half seconds before barging in, fearing the worst. Her eyes widened when she saw Kasenhis.
He was covered in scrapes and bruises, looking like he'd been through a battlefield. There wasn't a single untouched patch of skin left on him.
"Young people these days… Is this some kind of new fashion trend? Or did you actually get hurt this badly? Why haven't you gone to Madam Pomfrey yet?"
"It's not fashion," Kasenhis groaned, shaking his head as he scribbled the symbols onto a piece of parchment. "I just didn't have time to go. I've been working on a new alchemy technique."
Sprout sighed in exasperation but didn't push further. "As long as you're alright, I suppose. Oh, and here—take this." She pulled a small bottle of Essence of Dittany from her pocket and placed it on his desk.
"If you're too embarrassed to let the students see you in this state, you can patch yourself up with this."
"Thank you, Professor."
"Alright then, I'll leave you to your magical research."
Professor Sprout gave a polite nod and left the room, closing the door behind her. Almost immediately after, another scream—eerily similar to Tom Riddle's infamous wails—erupted from Kasenhis' office.
"Ahhhhhhhhhhhooohooohooo!"
"Kids these days... always up to something," Sprout muttered to herself as she walked away.
Kasenhis spent the rest of the day alternating between dabbing Essence of Dittany on his bruises with a cotton swab and studying the dense, intricate enchantment symbols scrawled across his parchment. The whole time, he could feel the weight of his efforts pressing on him.
His singular thought: Sleep.
The next day...
Evening...
Click-click-click...
Kasenhis carefully placed a thoroughly enchanted magical creature into a cauldron nearby. It was set to automatically notify the house-elves to retrieve it and take it to the kitchens.
His experiment was nearing success. According to the enchantment logic derived from the Enchanting Table, every object had its own set of unique enchantment symbols.
The same could apply to humans.
All I need to do is fill the gaps in the human enchantment symbols with the ones from the Ender Pearl.
But that last step was proving tricky—not because it was particularly difficult, but because the magical creatures' enchantment symbols were so densely packed that finding any space to insert the new symbols was almost impossible.
"Am I really going to have to try this directly on a human?"
"Will I die because of this?"
"Will I lose all my gear?"
"Like, will my entire office just get filled with an explosion of blocks all at once?"
"Would it look cool though?"
"Let's just hope I don't start shitting blocks... that wouldn't be cool.."
Alright, Kasenhis was not the type to maintain a serious mindset.
No matter how deeply he pondered a problem, intrusive thoughts always barged in, armed with absurd jokes that left him more exasperated than enlightened.
Knock, knock, knock.
The sound of knocking broke his train of thought.
With a wave of his hand, the door creaked open.
"Professor Kasenhis? We came to apologize," came Harry's voice as he entered alongside Neville.
Kasenhis glanced at the two young wizards. Just Harry and Neville.
"There's no need to apologize to me," he said, putting his hands on his hips and letting out a sigh of relief. "You just need to understand what you did wrong. Most mistakes can be fixed; what matters is that you learn from them and don't repeat them."
"Um... Professor, are you disappointed in me?" Neville suddenly lifted his head to ask.
"No, I'm not disappointed in any of you," Kasenhis replied without hesitation.
"Really?"
"Really," Kasenhis nodded firmly.
"That's a relief," Neville exhaled, visibly relaxing.
"Professor, I actually prepared a gift for you earlier. I hope you like it..."
Then, he reached behind his waist and pulled.... eh? Nothing?
" The gift box! I.. I think I left it here yesterday..."
'The scream that sounded really like Tom Riddle himself' is a reference to a Harry Potter play.
