Chapter 10 : The Last Touch
Naz was still standing…
looking at his hands.
"How… did this happen?"
The old woman looked at him for a few seconds… then said:
"You transformed."
"Transformed…?"
Chimini moved a little closer:
"You had… a horn…"
She hesitated…
"…and a tail."
Naz's eyes widened.
"I… don't remember anything."
The old woman said calmly:
"Whether you remember or not…"
She looked at Chimini.
"She was about to die."
Then she looked back at him.
"And you… are the one who saved her."
A heavy silence filled the place.
In a dark place…
desolate…
endless…
The faint light of a candle flickered…
A hand… writing.
Fast.
Madly.
The index finger… twisted.
The sound of the pen… sharp.
It stopped.
"Zehahahahaha… zeh… zeh… hahahaha…"
An amused laugh… terrifying.
"You want to play…"
A pause.
"We'll play."
Silence returned.
Naz clenched his fist.
"We're leaving… this place isn't safe."
The old woman shook her head.
"You two leave…"
She smiled.
"I'll only be a burden."
Chimini held onto her:
"Come on… come on!"
The old woman said in a quiet voice:
"In a few minutes… a beast will find me."
She sighed.
"I'd rather die… in my natural form…"
"Than live… as a demon."
Naz was silent.
He didn't know what to say.
The old woman stood up with difficulty…
She looked into his eyes.
"You never told me… what's your name?"
"Naz."
She smiled.
She closed her eyes.
"Thank you, Naz… I won't forget you, so—"
Suddenly
A piercing strike.
Her body… split in two.
Chimini screamed.
Naz froze.
A laugh came from behind:
"Chirichichichichi… chirichichichichi…"
He slowly turned…
Tears in his eyes.
"What did you do… Zagred?"
The creature paused.
"Huh?"
It smiled.
"How… do you know my name, human?"
But Naz ignored him.
Zagred: "Hey… Fate… why are you ignoring me?"
He grabbed Chimini quickly.
"Take this cloak…"
"And hide quickly."
The old woman…
Blood coming from her mouth.
Her body torn apart…
Naz ran to her.
He gathered her body… and put it together.
"Hold on…"
His voice trembled:
"This fight won't last long…"
The old woman whispered:
"Chimini… come closer…"
She approached with heavy steps…
The old woman touched her—
She lost consciousness.
"You've seen enough…"
Zagred moved quickly toward the old woman.
He smelled the blood.
He paused for a moment…
Then smiled a strange smile.
"Hmm…"
"This blood…"
He moved closer.
"…is not entirely human."
The old woman smiled with difficulty:
"Too late… for you to understand…"
Naz stood up slowly.
He looked at Zagred.
"Don't lower your guard…"
"You bastard."
Zagred tilted his head to the side quickly:
"You almost got me…"
"Chirichichichichi…"
