How Do We Eliminate Them?

I turned around and it's the sword manipulator of the class seven, Hirumi Saya. Just watch what am about to to, I respond, ' We've finished tying them!', Taruko State, I walked towards Taruko and the whole class four is tied up with one thick brown rope, All of them looked down and has frustration on their faces. I put my right hand on my pocket and grab a piece of rock, Taruko can you throw this rock higher than the wall?, I asked, Taruko flex his arm and smiled at me, ' Sure do!', I gave him the rock and he hold on to the rock, ' Beast magic: strengthening!, 5%!. Taruko thrown the rock on the air and you can see the wind braking, after some seconds, the rock didn't fall inside the wall, so that's mean that Taruko's throw was successful, ' how did I do?', The rock is outside, you've done well, Now let me handle the finishing touches. Search ability: eagle eye!', I search outside the wall to find the rock Taruko thrown, after some time, I found it, it's right next to a food stall?!, I didn't notice that earlier, maybe the stalls is for the hungry crowd watching us, but for now let's finish this, ' Swap Ability: Switch!', The class four suddenly vanished and it was replaced by a small rock, ' I understand now, You swap the class four's potion using the rock Tendo thrown outside the wall ', Yes that right Hirumi.
