MTL - Dragon Who Controls Time - ~ La

The male student, Fukai Nagamasa, ignores his studies for college entrance exams in favor of following the path to chuunibyou. As he fainted during night cramming session before the exams, he realized that he was transported to a parallel world as a feudal lord in the Sengoku Era. Not to mention that suddenly, he was marrying the sixth Demon King, Oda Nobunaga’s little sister, the one who was purported to be an unrivaled beauty?

The 13th disciple of the Great Mount Hua Sect. One of the Greatest Third-Generation Swordsmen. The Plum Blossom Sword Master, Chungmyung.

After slicing the head of the peerless Heavenly Demon, who threw the world into chaos, he slept an eternal sleep on the peak of the Hundred Thousand Great Mountains. Jumping over a hundred years, he comes back in the body of a child.

But… what? Mount Hua declined? What the hell are you talking about!?

It’s only natural to want to live if you’re going broke.

“Decline? Even though I’m here? Who would dare!”

Plum blossoms eventually fall.

But when the cold winter passes and spring comes, plum blossoms shall bloom again.

“But I’m gonna die first before Mount Hua gets revived! If you’re gonna go bust, might as well do it right, you bastards!”

The beginning of the Plum Blossom Sword Master, Chungmyung’s solitary struggle to save the thoroughly declining Mount Hua Sect.

King Grey has unrivaled strength, wealth, and prestige in a world governed by martial ability. However, solitude lingers closely behind those with great power. Beneath the glamorous exterior of a powerful king lurks the shell of man, devoid of purpose and will. 

Reincarnated into a new world filled with magic and monsters, the king has a second chance to relive his life. Correcting the mistakes of his past will not be his only challenge, however. Underneath the peace and prosperity of the new world is an undercurrent threatening to destroy everything he has worked for, questioning his role and reason for being born again. 

The older young Lisko woke up and found that he had become an American. He took over his father’s ranch and began to live in the United States.
