"Are you telling me this is Kumogakure's so-called treasure vault? Is the Raikage messing with me or what?" Kazama asked, turning to Yugito Nii with a frustrated sigh.
"Uh, well…" Yugito, sensing his irritation, gave an awkward smile. "Kazama, you gotta understand, Kumogakure's not as wealthy as Konoha. Plus, the Third Shinobi World War took a toll on our vault. A lot of stuff got destroyed. But even so, the techniques stored here are top-tier in the ninja world!"
"Fine, whatever," Kazama said, relenting at her earnest explanation.
He picked up the few remaining ninjutsu scrolls. Raiton no Yoroi (Lightning Release Armor), Raiden Senkō (Lightning Flash)… all lightning-based techniques, and all S-rank. Outside, people would kill for these, but Kazama wasn't impressed. His own ninjutsu were far stronger, and since he could absorb enemy techniques, he had no interest in learning these step-by-step.
"What's this?" Just as he was about to give up and leave the "treasure vault," Kazama spotted a yellowed booklet in the corner. It described a technique for turning ninja tools into chakra, merging them with the user's own chakra, and summoning them as weapons at will.
"Huh, this is pretty unique!" Kazama's interest was piqued.
When he'd first come to Kumogakure, he'd planned to bring his Kusanagi no Tsurugi (Grass-Cutting Sword) and Samehada (Shark Skin Blade), but their bulk made them a hassle for the long journey, so he left them at home. "If I master this technique, I won't need to lug weapons around. I can just summon them anytime. It's not the most powerful jutsu, but it's super convenient!"
Kazama waved the booklet at Yugito, signaling he'd take it.
Yugito grinned. "You're pretty lucky! That technique in there? It's one-of-a-kind in the ninja world!"
"Yeah, right," Kazama scoffed. "You're just worried I'll feel shortchanged and go back to the Raikage for more goodies, aren't you?"
"No, seriously, I'm not lying!" Yugito said, her tone turning serious. "You know Uchiha Itachi, right?"
"Itachi? What's he got to do with this?" Kazama asked, puzzled by the sudden mention.
"Everything! Years ago, Uchiha Itachi snuck into our village and used his Sharingan to copy the contents of that booklet. Then, based on what he learned, he tracked down the Jūken Tō (Ten Fists Sword) in the Land of Roots and the Yata no Kagami (Eight Span Mirror) at Ise Shrine. That means Itachi must've used this technique to fuse those two sacred treasures into his chakra. Think about it—a technique even an S-rank rogue ninja like Uchiha Itachi valued. Isn't that proof it's amazing?"
"Oh, I get it now!" Kazama said, the pieces clicking together. That's why Itachi's Susano'o could wield the Jūken Tō and Yata no Kagami—he'd fused those sacred treasures into his Susano'o using this technique.
If Kazama learned it, couldn't he fuse Kusanagi no Tsurugi and Samehada into his Susano'o too? It'd not only boost his Susano'o's power but also enhance the weapons themselves. Plus, his complete Susano'o was a three-headed, six-armed behemoth, but it only came with two Susano'o swords. Sure, they were strong, but it looked a bit underwhelming.
And according to Yugito, the booklet also listed the locations of other sacred treasures. Kazama's excitement skyrocketed.
"Alright! With this technique, I'll fuse Kusanagi no Tsurugi and Samehada into my Susano'o. And I can use the book to track down other sacred treasures for fusion too!"
Kazama couldn't believe his luck. What he'd thought was just a handy trick turned out to be a game-changer.
