That person is Kuwajima Jigorou, former Lightning Pillar replaced by his successor, Satriantar. He invited Halilintar and Duri to his house which was far away, located around the slopes of a mountain and surrounded by clusters of withered peach trees with a small stream crossing the backyard. There, Grandpa Jigorou lived with his grandson, a little boy with black hair and a gloomy face.
Visiting the house, Halilintar and Thorn sat by the burning fireplace with Grandpa Jigorou and his grandson. The little boy looked both curious and afraid of Thorn, hiding behind his grandfather who poured hot tea for his guest.
There were treats of ripe red persimmon and onigiri on a wooden dish with a bowl of miso soup, on the right. Grandpa Jigorou cleared his throat.
"It's very strange to hear that a devil still has a human side," said Grandpa Jigorou. "If only it wasn't a letter from my student Satriantar, I wouldn't have believed it."
"Can you guarantee it will last? Are you sure he'll be safe?" Grandpa Jigorou grunted. Halintar tightened his fists, feeling like an ant under a microscope.
"I have no guarantees except trust and belief," said Halilintar. "But I'll find a cure."
"There has never been a devil turned into a human. There is no cure," said Grandpa Jigorou as he sipped his tea. "It's all because of that ungodly creature."
A soft wind erecting its romantic feathers as Halintar shivered a little.
"What do you mean, Kuwajima-san?"
"Kibutsuji Muzan, the ancestor of the demons. He is the king of them all and controls all of them. Maybe he knows how to turn your brother back into a human," said Grandpa Jigorou.
Suddenly, adrenaline mended into Hali's vessels as he smiled. There are ways. There is a way to heal Thorn!
"Where is he? How to find him?" He asked, jumping to his feet determined.
"There's no way you can hunt down Kibutsuji Muzan now," said the former Pillar. "You have to meet the conditions." Thorn suddenly leaned on Halilintar's shoulder, fast asleep.
The older brother threw an apologetic look at Grandpa Jigorou as he lay down his younger brother so that he could sleep more comfortably.
"What are the conditions, Kuwajima-san?" asked Halilintar as he tucked Thorn with his haori. Grandpa Jigorou glared at him.
"You have to become a demon hunter and master breathing techniques. With that, maybe you can catch up to Kibutsuji Muzan and save your brother." Halintar leaned forward, unconsciously spilling some of his hot tea, openly enthusiastic.
"What do I have to do?" asked Halilintar.
The grandfather smiled faintly. "First, you must become my student."

I'm so so sorry for the late update!
I was unsure if I should continue this or not and put it off for way too long.
Again I'm really really sorry.
