Naruto World, Konoha Village.
Year 60 of Konoha. More than ten years had passed since Yoru Castle fought Minato Namikaze and Uchiha Madara and stopped the latter from controlling Uchiha Obito.
After the Third Shinobi World War, Minato officially succeeded to the position of Fourth Hokage thanks to his outstanding achievements and prestige, and married Uzumaki Kushina.
Yoru Castle had originally believed that, with Rin Nohara alive and Uchiha Obito not becoming Uchiha Madara's puppet, the Nine-Tails' Rampage would never happen.
Yet, to Yoru Castle's utter disbelief, when Kushina went into labor in Year 48 of Konoha while he was away on a mission, a masked man claiming to be Uchiha Madara still fucking appeared.

When Yoru Castle returned to the village and saw the devastation, along with the news of Minato and Kushina's deaths, he nearly went berserk on the spot.
Yoru Castle could not understand it. Uchiha Obito, that lovesick fool, clearly had not fallen to darkness, so why had the Nine-Tails' Rampage still happened? And who exactly was that so-called mysterious
