Anime Crossover: From the Start, I Marry Tsunade in Konoha and Travel Between Worlds in Demon Slayer

He transmigrated to Konoha at its founding and was the same age as the Legendary Sannin, but he had no cheats whatsoever.

There was no helping it. It seemed he could only flirt with Tsunade, pick fights with Danzo, and become an ordinary Kage-level shinobi.

But on his twenty-fifth birthday, the System suddenly awakened.

"Your life has returned to its normal timeline. Congratulations on awakening the Two-Way Portal System! You can freely travel between two anime worlds.

Main Naruto storyline: 1. Become the Ten-Tails' jinchuriki; 2. Rule the Five Great Shinobi Villages; 3. Destroy the Five Great Shinobi Villages. Completing any one of these will make you the Lord of the Plane.

May you soon become an unrivaled powerhouse who rules over all planes. Beginning random plane draw... Congratulations, you drew Demon Slayer.

Randomly summoning your retainer... Congratulations, you successfully summoned the Insect Hashira, Shinobu Kocho."

"Huh?"

Looking at the pretty young woman before me, blinking her big purple eyes with a bewildered yet excited expression, I couldn't help getting excited too.

Damn it, old Heaven, you've finally opened your eyes!

A relatively lighthearted, slow-burn story. The male lead is neither a bleeding heart nor a villain.
