Ronin and Ruka 

just as Ronin and Ruka where heading toward the exit a small group of 10 large dragons blocked their path they stood their and listened to the two dragons bickering and when it was done both Ronin and Ruka and they said 

"and we thought today was going to be just another boring day of training like another"

Ronin than walked up to Maka and said 

"didn't anyone ever tell you we humans are bad for your teeth"

with that he jumped at her and used Iron body to make his fist stronger and use a five finger pistol with a clenched fist that he called a pistol punch he hit her in the jaw and broke of one of her fangs 

"dont underestimate use humans"

he then looked to his daughter and nodded knowing what she was about to do 

Ruka then placed both her hand on the floor of the cave once again and as the circles on her hand began to glow again but this time the hole cave began to move the ceiling of the cave began to open up and the rocks that formed it retracted into the walls making the walls thicker and 
more sturdy she then stood up and looked to the Draco

"you wanted a fair fight well you can have it we will take care of the other 50 dragons you take out that Maka"

she then looked at her farther and smiled

"hay dad why dont we see how can take down more of these dragons"

"sounds fun but i wont hold back Ruka"

with that Ronin jumped at one of the dragons and used his tempest kick sending a wave of air cut of its head before it knew what was going on he then used moon walk to lift him higher in the air as he used his Density Manipulation to make himself heavier and plummeted towards it and as he hit it he crushed its skull while Ronin was doing this Ruka flew at one of the dragons used her Density Manipulation to phase though on of the dragons chests and grabbed its hart and flew out of its back while still holding its heart 

"i wonder how much i can get for a fresh dragons heart and for that matter dad what do you think that heads worth?"

she then used her Density Manipulation again this time she made herself bigger and grow to the size a dragon pulled out her spear with she ad also made bigger the she rammed it into one of the dragons chests as it tried to fly away
