Making the Senju Clan Great Again

[No System, no brainless protagonist, Senju clan, slow start]

After a stroke of incredible luck, he transmigrated to the world of Naruto and became Senju Ling, the orphaned son of the Senju clan in Konoha. Tsunade, a disillusioned gambling addict, took him in.

Under the influence of a master healer, he had hoped to become an ordinary medical ninja and spend a peaceful life under Tsunade's protection.

But when the "paper characters" who had existed only in his memories began appearing in his world, alive and real, he... could no longer stand by.

Yet fate is always unpredictable.

He couldn't change the destinies of his companions, which had long been set in stone. He couldn't even control his own life.

Only when he was imprisoned in a dark laboratory did he finally understand:

This twisted shinobi world was destined to collapse from the moment chakra was born.

"The age of the ninja is coming to an end."

He made this declaration during the Fourth Shinobi World War.
