My little sister is too cute, so I have to protect her!

"Fufufu... I'll start first, Yuuji-kun! Pawn f3!"

Uh... Does he even know how to play chess? I mean... that must be one of the most unorthodox moves one can make, right? Well... It doesn't really matter much to me...

"Pawn e5"

"You're going down, Yuuji-kun!!! Pawn g4!"

"Uh... Are you sure you want to make that move?"

"What, are you scared, Yuuji-kun? Let me tell you, I'm one of the chess clubs' aces in my high school. They even used to call me the kamikaze!!!"

Seeing that he made an extremely idiotic move, I just couldn't help but ask him if he wanted to redo his move. I... just can't bear to see his struggle anymore. It's too painful for my eyes. Therefore, I decided to put an end to his misery.

"Queen H4. Checkmate."

"..."

"..."

I... kinda felt sorry for him... I just didn't expect him to be this weak...

"So... does this mean that I can have your daughter now?"

"..."

"Hello?"

"..."

Ah... maybe I should just leave him alone for a while. It seems like he needs some time alone. Therefore, I decided to go back to the dining room and continue to take care of Charlotte...

************

"Hey, Charlotte! How are you?"

"Nya~~~"

"Nya!!!"

Yeah... I shouldn't have asked. Still drunk, huh?

"Come on, Charlotte. Get up. I'll get you to be, okay?"

"Nya~ Onii-chan is such a pervert~~~"

"Oi! Just what is in your head, Charlotte?!?!"

Despite her rather strange statement, I still dragged her onto her bed and covered her with a blanket.

"Stay there, okay? Goodnight, Charlotte..."

"Nya~! Onii-chan~ You can't do that to me~ No! Not that place!"

"Oi! Are you going to make me into a criminal?!?! I'm not going to do that with my won siste-"

Right before I finished that sentence, my consciousness interrupted me and made me think,

'Oh right... I did do it with my own sister before..."

"N-Nevertheless! Just what is going on in your head, Charlotte?!?!"

"Nya!"

"Whoa!"

Ignoring my question completely, Charlotte suddenly jumped up from her bed and then pushed me down onto it.

"Whoa! What the hell, Charlotte?!?!"

"Nya!!!"

She moved her face closer to me inch by inch. The feeling of resistance started to swell within me. But just before I could push Charlotte away, the door to the room opens.

"Fufufu... Hanako Nee-sama... It seems that he is even trying to make Charlotte his..."

"Death sentence..."

"Mio?!?! Hanako?!?!"

Sh*t. The two people who I don't want to be seen by the most in this situation are both here... I'm so dead...

************

Five minutes earlier...

"Mio, is this the place?"

"Yep!"

"Wait, did you hear that?"

"Hm?"

From a distance, the two could hear the cries of a girl. Upon further listening, though...

"Nya~! Onii-chan~ You can't do that to me~ No! Not that place!"

Silence covered the front of the house...

"Isn't that... Charlotte's voice? Nee-sama?"

"Mio..."

"Yes, Nee-sama?"

"Prepare the butcher knife. We're going in."

"Yes!"

Filled with rage, Hanako rushed in through the front door of the house an barged to where Yuuji currently is...

"You're so dead, Yuuji..."
