Chapter 10

You glanced at the room and saw Watari pinned into the corner by a burly security guard with tattoos and scars all over him. Watari was tied up and gagged, with a fearful look in his eyes. You looked him up and down and saw that his clothes were stained with blood and his muscles were trembling. You gave him a look as if to say 'it's ok, I'll get you out of this', but by the state of Watari, I don't think this made a great difference. Then, you heard the door open behind you and yet another security guard filed in through the small gap.
"We need to ask you a few questions,or the butler gets it." Said the man behind you gesturing to Watari.
You looked Watari in the eye and he gave you a worried look, slightly shaking his head.
"Well then... Let's get started..."

The man pushed you towards the security guard who grabbed your wrists.  You flinched at the tight grip, but didn't say anything. When the man pulled out a rope you kicked him from in front and he doubled over in pain.
"Oh, you're doing it this way are you? Well, let's see how long this takes me..." The man said whilst cracking his knuckles. You advanced towards him and he flung a punch aimed at your face. You dodged it by about an inch and then kicked him in the groin. He stumbled forwards and then you stuck your foot out and tripped him up. He lay sprawled on the floor, weak and tired. You straddled him and kept him on the floor. In the midst of all this, the other security guard in front of Watari had fled, obviously scared of how well you defend yourself.
"Watari, can you kick me that rope?" You said and your command was followed. You picked it up and tied the man's hands behind his back. Then you found another piece and tied his feet together, so he couldn't walk.
"Watari, are you alright?" You asked as you untied him and took his gag off.
"Y-yes. I am ok..." He said, stumbling forwards a little bit.
"Here, lay on this bed. I'll phone Ryuusaki and get him to come here." Just then, Ryuu burst through the door.
"Watari! (Y/N)! Are you ok?!" He said and then saw the men strewn across the floor, tied up and groaning in pain.
"(Y-Y/N)? Was this you?!" He asked in amazement. You nodded sheepishly, embarrassed about how well you fought.
"I can confirm that this was all (Y/N)'s doing, and I can't really believe she saved me!" Watari clarified.
"W-wow! I have a self defence master for a girlfriend!" L said, blushing a little as he said this. Just then, police burst through the door and grabbed the men tied up on the floor.
"We will take these, we know exactly what has happened, the person watching the surveillance tapes called us, and told us everything." A man in police uniform said. "You two are free to go, while we take this man to hospital.
