Ten Years of Sign-Ins in Konoha, Then I Woke Up to the Fourth Great Ninja War

After ten years of signing in at Konoha, he never expected to wake up in a different world. The Whitebeard Pirates were bearing down on Marineford, and he had somehow been assigned to the very front as an ordinary Marine soldier!

“So that means nowhere has been signed in yet, right? System, start signing in.”

Sign-in successful aboard the Moby Dick. Reward: Kaido's spiked club.

“Thunder Bagua... What the hell? Where's my club?”

Sign-in successful at the seats of the Three Admirals. Reward: one chance to summon a member of the Akatsuki.

“Art is... Ron? What are you doing here?” Deidara was about to blow himself up to take Sasuke down with him, but Ron drew him by chance, and he appeared at Marineford.

But the self-destruction could no longer be stopped. Boom...
