Rider
Rider sighed at the girl's condescending response, annoyed that she was unwilling to explain the situation any further. She could, of course, be telling the truth but, equally, if she were intent on tricking them, she would hardly inform them of that. However, before Rider could make any kind of response, the girl dropped down from the rooftop, landing on the ground below near to what Rider could sense was Sakura and her sister. Frowing and sighing again, Rider dematerialised and allowed herself to fall through the floor, landing on the ground in between her master, who seemed to be wrestling Rin for some odd reason, and the approaching girl who claimed to be Vanguard. Then, once safely on the ground, she re-materialised herself, taking a protective stance in front of her helpless master.
"Oh? I believe I missed something interesting. It is rather risque but I suppose it would be exciting to do that so exposed. Should I join in? I wonder why Rider isn't helping. Hmm. Questions for another day", the girl said, mockingly, before addressing the two of them.
"Sakura, Rin, you can finish up whatever it is you're doing inside. Perhaps on a bed? I've heard that it's more comfortable. But first move out of the way and make Rider do so as well. I'm hungry", she continued.
Rider frowned once more, annoyed at the girl's mocking tone towards her master and her presumptuous demands. Before she could say anything, though, Rin addressed Sakura.
"You know this bitch is ordering us around, and we have other visitors", she said, pointing at the two people approaching them, a blonde girl and a silver-haired guy.
Rider, however, was still focussed on the girl in front of her, the one who claimed to be Vanguard.
"Sakura asked me to stop you, so you are not getting past unless she asks me to move. Now, please, explain why you sound like Vanguard but do not look like him", she said, clearly irritated by her refusal to answer a simple question.
