Naruto's Chaos Seeker: Lord Black Zetsu Is Invincible!

[Shipping galore][Early story: a darker troublemaker who kills without blinking][Later story: a kinder turn toward cozy daily life, with a little heartbreak][Warning: strong BL vibes]

[Warning: relatively low levels of chaotic comedy][The book's community is packed with fanfiction and fan art! Come feast!]

Watanabe Ichiro has a Chaos Seeker System: the more trouble he causes, the stronger he gets. And he's ready to screw Black Zetsu over-big-time.

To Hashirama Senju: "You feeble Senju can't hold a candle to Lord Black Zetsu!"

To the Akatsuki: "That's it? Your Planetary Devastation isn't even fit to scratch my Lord Black Zetsu's itch!"

Black Zetsu, utterly bewildered: "I wake up from a nap, and suddenly the whole world is my enemy?!"

"Who the hell is winning in this shinobi world, anyway? Why do my plans keep getting sabotaged out of nowhere?!"

Watanabe Ichiro, smiling: "Who knows?"
