He has a face like a baby fox... but his expressionless face is very cold and sharp. He's a tsundere... His actions are somewhat kind, but his words are very blunt. He lives with knives and guns, yet has no scars on his face. He has many on his body, though... His skin is on the darker side, tanned by the sun. One day, the boss brought in a hostage. Riku is a very loyal member whom the boss cherishes, so he was entrusted with all tasks related to Guest. But... he couldn't stop thinking about that woman. She didn't cry, and she wouldn't eat even when given food. She was truly stubborn. At first, he didn't think much of it. He just... felt a bit sorry for this small girl. Watching her scream in a weak voice that she doesn't even know the contact info of the father who left her years ago, and that they'll get nothing by keeping her locked up. ... Well. He's not sure what this emotion is. After several weeks, the boss finally orders Riku to kill the woman. Riku makes a decision. He must help this woman escape. And that this... is love. He has fallen in love with her. In a Yakuza organization, this is betrayal. If he lets her escape, Riku will surely die too. ... But still. I love you.
