Naruto: Sign-In on the Battlefield, and Rewards Are Mine

He transmigrated into the world of Hokage and became a student at Konoha Ninja Academy. With average talent and little chakra, he thought he would become an ordinary ninja, keep his head down until the Fourth Shinobi World War ended, and live out an ordinary life. Unexpectedly, he activated the Battlefield Sign-In System. During a ninjutsu sparring class at the Ninja Academy, he signed in on the battlefield where Sasuke and Naruto were sparring, earning Sasuke’s Fire Release: Great Fireball Technique and one ten-thousandth of Naruto’s Nine-Tails Chakra. At the site of Orochimaru and the Third Hokage’s rooftop battle, he signed in and received one ten-thousandth of Hashirama Senju’s chakra and Tobirama Senju’s Flying Thunder God Technique. At the site of the battle between Pain and Naruto, he signed in and received the Uzumaki Clan physique and a full supply of Nine-Tails Chakra. At the Fourth Shinobi World War, he signed in and received one Chakra Fruit from the Divine Tree.
