Starting from Naruto, Playing with Space!

Naruto · Space · Sage Arts · Decisive and ruthless · Multiple female leads

In the 39th year of the Konoha calendar, Feng Xiangyu is born at the edge of Konoha into a down-and-out swordsmanship family carrying a portable space with a radius of five meters.

His neighbors are the still-snot-nosed Moonlight Hayate, and Uzuki Yugao, who follows him around every day calling him "big brother."

Born into a small family doomed to become cannon fodder, Yuichi does not panic at all. Instead, he quietly begins developing his cheat ability: the space automatically absorbs natural energy to strengthen his body; after cultivating chakra, the space turns into endless mana; he can even perfectly fuse chakra with natural energy, perform sage arts instantly without hand seals!

The Third Shinobi World War breaks out, and Yuichi, who has graduated early, tightens his grip on the long blade in his hand.

From the "nothing can be cut" sword technique that coats his blade with spatial power, to the self-created "Flying Thunder God Slash" using spatial coordinates.
