My Little Sister Cute Outside, But Yandere Inside!
Chapter 11 - Chess Match, but...

After lunch and the progress report of the plan I gave, Chiyuki and I rushed towards the living room.

Right after I opened the door, in front of me was a little boy smiling at me. From a distance, I could see her long ears that indicated she was an Elf.

No doubt he is Mercedes. Based on his physical appearance, he looked like a boy but his age said otherwise. I was confused to find a suitable nickname for him. I guess.. Mercedes is better suited to the usual calls as young people in general.

The respect and admiration for the person who will shake the future is mixed in my heart.

Eh?

Better not to! If he becomes my enemy. That would be a little troublesome. I don't want to have an enemy that always makes me think three times about stepping.

Even in our previous lives, we were equal enemies. Events such as contesting the territory and herding public opinion we always do. Of course, all of that was done in the shadows.

He and I are enemies fighting in the shadows.

I could feel an old sensation that had been lost, an adrenaline rush to face an enemy that exceeded my predictions.

In front of him was an empty chessboard and next to it was a chess piece. I can understand what's going to happen.

When Chiyuki and I sat together. Mercedes put the chess piece on the board.

“Very interesting.I never got an offer to cooperate with King and Duke at the same time. Luckily, I have a method to measure the ability to choose this offer” Mercedes said.

It could be said if he wanted to measure the Duke and King's abilities.

Well, he could not afford to heed this promising offer since both of them possessed the same power.

I understand a little bit about his mindset. I was the same, choosing something sure to do.

Chiyuki accepts the Mercedes challenge and begins to compile her chess pieces.

In chess, the ability to think, predict, and risk-taking courage will be tested. But, is Chiyuki able to match the capabilities of Mercedes?

I can't expect much from Chiyuki but this is my chance to assess Mercedes' capabilities. The enemy that always troubled me in my previous life.

“But..this is no ordinary chess match. Each piece that is lost is equivalent to unbinding the clothes that are worn.”

Chiyuki was surprised when Mercedes said the rules of the match.

“Isn't it more interesting to be able to see each other? I'm sure your Onii-chan will be so happy to see your body.”

Don't take me to your matches!

Well, I can't refuse this offer.

I could see Chiyuki staring at the Mercedes. The look was filled with anger and fervor.

Chiyuki started running the pawn.

I calmly observed the match of the two of them.

A Mercedes with aggressive moves began to fill the strategic point of attack while Chiyuki began to form a defensive formation. At first glance, the formation they used was the standard formation of the chess game but I could feel the Mercedes starting to move actively in attack.

Each piece moved by Mercedes has the potential to destroy Chiyuki's defensive line. Almost all of Chiyuki's battles can only go around in circles without leaving the defensive line and Mercedes is slowly exploiting it to fill Chiyuki's potential defensive breakthrough.

Seeing their match both of which went on without any process. I doubt Mercedes' abilities.

“Yeah, I think it's enough to play around. Onii-chan. please enjoy your sweet Imouto body.”.

What does that mean?

Slowly, I began to understand what Mercedes was saying. One by one the pawns began to eat the Chiyuki pawns. The sturdy fortress of Chiyuki slowly collapsed by the Mercedes attack.

Chiyuki who was focused on defending could only rotate the defense rotation to protect her King's piece.

Something is wrong here.

I could see the rotation of the Mercedes attack exceeded the three-step prediction as if he was reading Chiyuki's mind about the defense plan he was going to execute.

Slowly, Chiyuki began to take off the clothes she was wearing leaving thin clothes attached to her sweet skin.

Seeing my sister's situation like this, I think I should intervene.

“It's interesting, can I replace my sister?” ask me suddenly.

“Eh? Are you sure Onii-san? Even your Imouto pawns have almost lost completely. Don't you want to see your Imouto sweet skin?”

“Yeah, I do want to see it but. I prefer to enjoy my sister's sweet quit alone.”

“Fufu.. I envy your proximity.”

“Yeah, I love my sister very much. If only she wasn't my sister, I'd definitely want to marry her.”

“Wow!!” Mercedes was a little surprised by this joke of mine and Chiyuki held back the red hue of her face while covering her exposed body.

“Well, I think I need a cup of tea. Can I make tea first?” ask me.

“Please...”.

I rushed to make some warm tea in the kitchen.
