MTL - Comprehensive Manga: The Wandering Ninja World Started From Questioning Payne - Chapter 44 Calculations and the Chunin Exam that started early (Kneeling, Lord, understand?)

An F-Class Hunter.

And on top of that, a F-class older brother who can’t even begin to catch up to the heels of his amazing S-class little brother.

After living a life that fell to pieces and even destroying my little brother’s life,I got another chance by regressing 5 years back. I picked up the resolution:
This time, instead of making those mistakes, I will quietly live my life leisurely .

Is what I thought… but the S-Ranks are all kind of… weird and for some reason I can’t seem to be able to get away at all?

“Is this really a f*cking cannon fodder counterattack system???” Zhou ZiRuo transmigrated into a game and became a shapeshifting, cannon fodder, baby fox demon.

As a new (male) fox demon, he thought his task was only to counterattack the gold-fingered, peerless, super explosively cool, iceberg protagonist.

But why did the iceberg protagonist seem like he was possessed by a death god, with NPCs dropping dead left and right everywhere he went?

Why must he help the protagonist investigate the incidents or else the counterattack percentage would fall through the floor, leading to his death?

As Zhou ZiRou wearily investigated the supernatural cases, at the same time, he walked down the grand path of counterattacking the protagonist and kicking him to the curb.

Yet no one knew that under the iceberg protagonist’s calm and proper exterior was a heart that was both kuudere and wicked.

System: Congratulations! The counterattack was successful!

Zhou ZiRou: You motherf*cker, you never said that I’d counterattack into the role of the female lead ahhh!!!
