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

After another vicious round of beating ended, Yuuji decided to walk over to Haruto and check him out.

"Yo, Haruto. How was your beating, eh?"

"... You could have just stepped in and helped me, you know?"

"Ah~~~ I can't. If I did, I would probably have been beating up along with you, right?"

"..."

Patting him on the back, Yuuji gave him a bottle of water and untied him from the bungee cord.

"Oh, don't make a face like that, eh~~~ Just relax!"

"...I would have done that already if I hadn't been beaten up by my own sister and a girl who had beaten me up before."

"Ah! So that was the girl you talked about, eh?"

"Yes... I no longer hold a grudge against her, though."

"Huh?"

Surprisingly, after getting beaten up twice by that girl, he no longer bore a grudge against her. Just what sorcery did that girl use to quell his anger?

"Well, at first, I was extremely angry, but hen I finally saw her face when she was beating me up, I finally found out that she is also a victim like me."

"Eh? How come?"

Not bothering to explain, Haruto pointed his thumb towards where the three girls were standing. Although the three seemed to be chatting happily with each other, upon closer inspection, it can be seen that the twin-tailed girl is actually straining herself to keep up her smiling face.

"Ah... I still don't get it..."

"... You don't have to try to get it, Yuuji. It's only something that victims can understand."

"..."

"Ahahaha... I-I need to get on the passenger boat right now... So... Please let me go..."

Nobody remembered how many times the girl had begged for Mio and Erika to let her go. In the first half of the sentence, she was still able to retain her usual tone of voice, but in the latter half, it sounded as if she is about to cry at any moment.

"Ma~~~ Don't go away yet! Let's have some more fun together! Alright, to the next game, Erika!"

"Okay!"

"P-Please wait!!! Please let me go!!! What do you want?!?! I'll do anything! BUt just please let me go already!"

"Eh? Did you not enjoy the game?"

"N-No, but... I don't think that I can keep playing it any longer!"

"Why? I thought that you had mercilessly beat him up when you first met him?"

"I-I have! But I was wrong! Please forgive me! I shall not bring harm upon him again!"

"She said that, Erika. So, what do you intend to do?"

With a sadistic grin on her face, Erika replied.

"I'm going to teach her that no one can beat up my brother other than me. He may be just a slave, but he is mine. Mine alone..."
