Check-In system in Naruto

Izumi finds himself transported to the Naruto world, where a simple check-in grants him the abilities of various ninjutsu, tools, and bloodline limits from the characters in the series. As his goodwill towards the characters increases, he unlocks unexpected surprises! Kakashi: Where did this kid learn the Eight Gates technique? Tobirama: Damn, how does he possess the Susanoo? Nagato: Almighty Push! Kid, interested in experiencing a Double-Edged Bomb in Konoha? Hashirama: Come on, kid! Let's have a real brawl with thousands of hands! At this moment, Izumi stands before Kaguya Ōtsutsuki, wearing a charming smile. Kaguya, would you mind checking in for me?
