HP: Spirit Talker

Several times, Professor Snape took out oblong vials with poisonous contents and tried to throw them at the stubborn Asian. But each time, the white paper birds undermined the Battle Alchemy, forcing him to neutralize the too-close threat with other alchemy.

Eventually, the man was forced to stop — the neutralizers ran out, and most combat alchemy has the property of various gases and aerosols — for increased effectiveness. That's not to say that Hoshino "overwhelmed" the potionist with attacks, but he didn't let him stop for a second, and the spells and curses he sent out were intercepted by more and more birds, giving the guy time to recover.

By the way, it was only now that Hoshino drank an unfamiliar milk-colored potion for the first time, and in an unusually large amount — with a good cup of tea.

But the potionist wasn't exhausted yet. His attacks stopped for a moment, but then he let out a huge wave of shaking air that tore all the paper birds apart. The man knocked over a few more potion vials, stopped, and began throwing rocks and large chunks of earth at the boy. In response, the boy simply waved his wounded left hand, which held a shiny wand.

Snape's projectiles scattered into harmless dust each time, and the boy moved cautiously to the side until he reached the fallen wand, which immediately leapt into his right hand. A wave of light from the wand and a shaft of red ruinous flame moved toward the potionist, but he used alchemy again — flashes of green fire and the wave dissipated. But a powerful Reductor immediately flew into him, knocking the man back about ten feet. For the first time, all of his shields were pierced, and white writing flashed across his leather armor, saving him from critical injury.

Severus Snape was just beginning to rise, but he had to hurry, for this time Hoshino lunged forward, releasing another dozen talismans that swirled around him as the second shining wand managed to disappear. Snape raised his wand and shouted, but his words were indistinguishable from the sound of the explosion.

Whole clusters of orange-sized purple spheres spread out, causing deafening bangs and flashes of purple fire on the ground, their explosions leaving half-meter-wide craters, heavily molten. Behind the raised smoke and flashes you can't see what's going on — everything is covered...

— AAAAA!

A flash of white and golden light, accompanied by a man's scream of pain. An explosion and Snape flies out of the dust clouds, still casting some magic in flight, but then he is overtaken by a dark figure, only three talismans left spinning around. A chain glowing with golden symbols extends from the man's hand.

A somersault in the air, and the extended chain stabs the potionist, creating a new flash of white and gold light from the collision of the dragonskin rune armor and the artifact weapons, and a new scream of pain. The crowd expected the attack to continue, but Hoshino, unbelievably bent in a leap, inexplicably created a blue flash under his feet, literally pushing himself out of the air and bouncing off somewhere to the side.

The people had not yet realized what they had seen, as a few claps in the place where Hoshino was and should have been if he had continued the attack produced clouds of poisonous pink, green, and yellow, and a moment later there was a massive explosion. When the smoke cleared, everyone could see an incredible scene: the rune armor was in shambles, the dragon skin smoldering and disintegrating.

The sorcerer's face had turned into a mask of hate, his right arm was drooping, and his cheek was bleeding from the shattered gash. But Hoshino wasn't taking it easy either; he was swaying slightly, breathing heavily, but his gaze remained fixed on his target.

The necklaces were large, dark red beads with hieroglyphics burned into each bead. Before the people's eyes, the string of beads retracted into a sleeve, shortening to half a meter, and Hoshino moved forward, toward his enemy.

Snape wanted to boil Dumbledore, who had agreed to the phrase "...weapons of steel..." in a cauldron, but there was nothing he could do. The wizard could not take his eyes off the monstrous weapon, from whose blows his armor could not protect him, and the soul-crushing pain was worse than Cruciatus. Unwilling and frankly horrified by the new blow, the wizard cried out:

— Fiendfyre!

A shaft of red flame shot from the man's wand, transforming into a sinister chimera, but no sooner had it grown than ....

— Partis Temporus!

The spell, creating only a temporary passage in the hellfire, literally tore the still small fire apart. But the stream of red flame from the wand didn't stop, and he was about to point it at the Japanese man again when a translucent, blue-gray wolf's head the size of a horse's head emerged from the ground and closed its hideous jaws on the man's pale wrist.

Before he realized the pain, the potionist heard the crunch of his bones, and a moment later, along with the pain, his wand arm fell to the ground, accompanied by a spray of blood.

The battle potions had dealt with the shock, and the man was already reaching for a spare wand when the world spun around him, and then the hated upstart came into view, a blue translucent blade shining in his hand. An eerie realization flooded his dying mind, but his lips were no longer capable of sound. The last thing Severus Tobias Snape saw in his life was the indifferent face of the Japanese man and the blue sparks from the wizard's sword that had beheaded him. Darkness engulfed the wizard forever.

As soon as his head froze to the ground, the glowing curved blade scattered sparks and the man himself swayed slightly, kneeling heavily by the corpse. The duel was over. People reacted differently. Some simply noted the fact and walked away, some thoughtfully stored the memories in a crystal vial, some frowned like the headmaster of a magic school, pressing their lips together and trying not to show too much indignation on their faces.

Others, like the French girls who rushed up to him, were openly rejoicing, either because they had won a bet or simply because he had won. But most of all, Dumbledore didn't like the way the narrow-eyed barbarian had covered the Potions Master's head with seals, then hidden them in a bag and handed them to the former Auror.

There was nothing more for him to do here — the Headmaster, having summoned a phoenix, disappeared in a bright flash of fire. Those who did not leave immediately got to see an amusing picture of a loud argument between the French and the Chinese on the subject: "whose healer will treat the boy". Lucius Malfoy and Henry Greengrass left the scene of the duel a few minutes after it began.
