He was right, the world he went into is the world of Naruto. The man in front of him is the very proof of that. Hatake Kakashi, one of his favorite characters in Naruto.

He is knocked out of his stupor when Kakashi spoke to him.

"Hey kid, what're you doing outside here?" Kakashi asked with his mouth covered in his lower face mask.

"Uh, I don't know, " Hikaru lied. He just can't tell them, "Hey I'm from another world on a quest to seal an ancient god that has gotten out of its seal" ya know?

Kakashi looks at him suspiciously and said, " What do you mean you don't know? You're out here, all alone without anyone to accompany you."

Hikaru then decided to tell him another lie but, "I don't know how I really got here, but I can tell you a bit of my land if you would lead me to your leader."

Kakashi contemplated it and said menacingly, "Fine, but if you do anything funny, I'll dispose of you."

Hikaru, terrified, said, "D-don't worry, I won't, " while waving his hand in front of him.

Kakashi put his hand on Hikaru's shoulder without any warnings and felt it was a little cold but he ignored it before using shunshin to go to the Hokage tower.

*********

(Hokage Tower Office)

Hiruzen sat behind the desk full of papers while stamping them one by one with his stamper, when he suddenly sensed Kakashi and a unknown individual coming towards his office via shunshin.

Hiruzen wears his Hokage robe, his skin is light, his hair is grey, his face is gaunter, and he has the wrinkles and liver spots of old age. 

He stops what he was doing and he looks in front of him before Kakashi and an unknown child appeared in front of him.

Just after the child lands on the office floor, he immediately threw up.

"Yare, yare, I think I should've warned you I was gonna use shunshin to get you here" Kakashi scratches the back of his head when he saw that.

After finishing, Hikaru glared at Kakashi and said angrily, "Can't you just warn me about that?"

Kakashi eye smiled and said, "Then it wouldn't have been fun."

"You!"

"Ahem! Tell me, what is this child doing here with you?" the Hokage asked sternly.

"Uh, you see, I was just returning from a mission when I saw this kid laying right next to the village's gate. He was kind of suspicious and he told me that he will tell us about his land if I bring him to you, " Kakashi explained.

Hiruzen seems interested in what Kakashi's talking about, he looks at Hikaru and asks, "So, what land did you come from, boy?"

Hikaru got a little annoyed that Hiruzen called him a boy, when he is over 16 years old, but he just ignored it and replied with a lie to his question, "I came from the land of Lordran that was ruled by the Lord Of Sunlight, Gwyn. In my land, eternal dragons once ruled it before Lord Gwyn came."

"Wait, dragons? Aren't they just myths?" Kakashi asked him.

"No, they weren't. Wars were fought before the three lords managed to destroy them--" Hikaru continued but Hiruzen cuts him off.

"What do you mean they destroy them, aren't they eternal? Then how did they got destroyed?" Hiruzen asked.

Hikaru was getting annoyed with all their questions, but he kept his calm and continued explaining.

"Because one of their own betrayed them, Seath the Scaleless. The eternal dragons were able to live eternal because of their immortal scales, but there was a secret they were hiding, their weakness. Lightning. Their scales were extremely weak to lightning and Seath being jealous of his brethren' immortal scales, told Gwyn on how to defeat the eternal dragons. So Gwyn used his divine lightning to pierce their scales, Nito, The First Of The Undead, spread disease to their ranks, and the Witch Of Izalith and her seven daughter of chaos destroyed their archtrees."

Kakashi then asks, "Then what happened after?"

Hikaru looks at Kakashi and said, "Then Gwyn's light came, instead of just killing Seath right in from of him, he gave him rewards. Being a duke in his kingdom, the hand of his first daughter, Gwyenevere, and a part of his very own lord soul--" Hiruzen, again, cuts him off.

"You kept saying lord soul, what are they?" Hiruzen asked curiously.

"It's hard to explain, but I'll do my best. The lord souls came from the fire. The fire which Gwyn greatly desired. He became the hope of his entire race because of this fire. This fire is a part of the great nature itself, that's why the powers that came from it was so powerful."

"So what happened to the fire?" Hiruzen asked.

"The fire burned out and darkness was spreading to the land, but it was all part of the great nature for humanity to rise up, unfortunately, Gwyn decided to go against mother nature herself. He lit the flame using himself as the fuel, " Hikaru explained.

Now, Hiruzen is greatly confused. "Weren't Gwyn a human?"

Hikaru shook his head and said, "No, Gwyn wasn't a human, I don't know what race he is but I think he was a part of the race called Gods. Gwyn and his race were literal gods, I think."
