The Next God of Anime

A boy in casual clothes holds the Fantasy Greatsword, Heavenly Demon Starfall, with a little demon perched on his shoulder.

"The evil dragon shall fall at last."

"Light and shadow that sever all things."

"The world has now reached the hour of sunset."

"I shall strike you down: Fantasy Greatsword, Heavenly Demon Starfall!!"

He swings his sword and slashes forward.

(P.S. A true harem, a true harem, a true harem!!! Some things need saying three times.)
