Kaito's transmigration into the Naruto universe delivered an unexpected twist: he's now Sasuke's twin brother. With the Uchiha Massacre approaching, his fortune improved when his system awakened—only to plummet when he realized how broken it truly was. His system spouts nonsense about the non-existent Green Hill Fox Clan, searches for phantom Grand Soul Masters at Konoha's gates, and obsesses over recruiting him to an Immortal Sect despite their shinobi setting. The system perpetually confuses cultivation world mechanics with ninja powers, making Kaito question whether he'd transmigrated to the wrong world or if his system had suffered a complete malfunction.
