"You heard that on this hill there are the ruins of an old castle" said Shikadai
"Really?"
"Maybe we should check him out" Boruto suggested, looking interested in the idea
"But apparently this castle is haunted, and that's why no one goes there" said Inojin
"Do you believe in these fairy tales, don't be a child" Sarada sneered
"Okay, but I don't like this idea"
Late in the evening, a group from Konoha went to visit the ruins of an ancient castle, when they got there they saw a destroyed castle
"You know, maybe we shouldn't go in there" Sumire suggested "It doesn't seem like a safe place"
"Don't be afraid, we'll be fine" Shikadai said
When the group opened the door, many bats flew out from inside the castle
"KYAAAAAAAAAAAA!" All the girls except Sarada screamed in fear at the sight of the bats, while the boys just laughed at their reactions.
"But it's full of dirt and dust" Shikadai noted
"What did you expect, these are ruins after all" said Inojin
The group started exploring, at some point Boruto found an interesting room
"What did you find there?" Sarada asked
"It looks like a library, look, it's full of different scrolls"
"You're right, but look at this scroll"
When Boruto read the fragment of the scroll, he noticed that it was about Otsutsuki and depicted the story of Kaguya Otsutsuki and the sage of six paths
"And what will we do with that?" Sarada wondered
"I will create a barrier around this castle, no one will enter it except me"
Soon Boruto and Sarada joined the rest, after they finished exploring, Boruto created a barrier around the castle
Next day...
The group of teenagers returned to Konoha, Boruto and Sarada went to the Hokage's office where they told Naruto about the castle
"So you found the castle that belonged to the sage of six paths?" Naruto said
"It looks like we also found a library with various scrolls" Boruto threw one of the scrolls he had taken to Naruto.
"This is about Kaguya"
"Not only that, but there were also scrolls describing how to oppose Otsutsuki. It looks like Hagoromo predicted that in the future, Otsutsuki will attack our planet. I'll contact Toneri about the lock and the scrolls"
"Okay, thanks for telling me, I'll definitely check out that scroll"
Boruto nodded and he and Sarada left the building
"You know your birthday is coming, have you thought about what you want to do?" Sarada asked
"So much has happened recently that I forgot about it"
"Then leave it to me"
"What did you say?"
"Nothing, it doesn't matter"
