The two girls began top stare at eachother with hate and coldness in their eyes completely ignoring the third person in the room and the room itself that was disgusting to the point of people wanting to Nuke the house
after some seconds of staring daggers on eachother Ruby uses her semblance as she disappear in a burst of Black petals
Ruby then apeared in front of Yang in some miliseconds
after geting in a confortable podition Ruby throws a puch to Yang's abdomen
but Yang apears to be prepared to this action a long time ago as even before Ruby used her semblance she had her hand prepared on her abdomen like she is familiar with the atack pattern that Ruby uses
so with preparation Yang sidesteps and grabs Ruby's arm using the puch momentanium she pushers Ruby's body foward and like a hammer hamering a screw Ruby's head met the ground making her aura act up and blocks a good amount of damage but she broke the woden floor of the house as the momentanium of Petal Burst and Yang's force is not a thing to be joked around with
so in conclusion Ruby is predictable and naive in figths making she lose in the first moviment
as for Yang... we dont have any material to judge her yet as the only thing we can get an conclusion is that she is familiar with Ruby's atack pattern and have atleast a good reflex because its not every day you can find someone that can react to this type of speed
after basecally hammering her own sister to the ground Yang's coldness are replaced by interest and a bit of lust as she looks at the maked boy that is looking at the duo with a bit of amusament even if people cant tell because the mask and even without the mask you cant really tell any emotion
she looks at the boy with a eyes that seam to scream 'look at how this beautyfull elder sister smashed the bad girl to the floor, praise me'
while her thoughts are almost like ' what that stupid rose is doing with such a strange boy in the middle of the nigth'
sudenly Pitou asks
"Miss pedophille, can you tell me why your house looks like a whore house that hasnt been cleaned up for seven centuries ?"
Yang and Ruby were stuned by the question as kids this guys age shouldnt know what a whore house is, and Miss pedophille is a bad way to call someone even if in this case its true but have some respect for your elders you brat
