Be careful of what you wish for chapter one

Brixujel was enraged more then he ever was, as he stormed out of his room fitfully.  Once again, he had to drop everything he had wanted to do, just to watch his 13 year old, bratty, annoying, pethedic, little sister, Molly. 
"Molly gets in my way of everything..." he fumed. 
"This time, everything will be okay though, " Brixujel muttered, sighing to calm himself.  "I get to go to my friends, and play an awesome video game all day...And be the first as a tester!  " he rejoiced.
"After three whole months of planning, and preordering..." he murmered, grabbing the rest of his things from school, and putting them in his backpack. 
"All I gotta do is get home, dress in regular clothes, and flee the scene as fast as I can.  " 
He arrived home, put his video game gear in his backpack, and opened the door to leave, when he heard the dreaded words.
"Hey, Brixujel, your dad and I need you to watch Molly for awhile.  " Brixujel's mom shouted before he could even step on the steps of his porch. 
Brixujels fury arose like the power of a nuclear bomb, ready to explode at it's destination at any moment. 
"B-but mom!!  " he sputtered out madly.
"I've been planning this 3 months,  " He wailed. 
"Why can't I go?!  "
"I have to take care of some events at work, and your father has to take his friend fishing this weekend like he's been putting off.  " she replied, miffully. 
Brixujel rushed down the stares crazily, knocking down some items while he passed, and opened his door ferociously.  He slammed it hard enough for it to fall of of it's hinges, and the rest of the wall around it fell off.  He pounced on his bed and started pounding the nearest things, the tables, the floor, the bed. 
"UGHH!  I WISH THAT MOLLY WOULD JUST DISAPPEAR!  "  he thundered. 
Suddenly, a scream rang through the halls, and the rooms, of the whole home. 
"Molly?!  " Brixujel cried, running staight into her room. 
A shadowed man with a nightly cloak had his arm around Molly's mouth, as she struggled to get out of the man's strong grip, one arm reaching to Brixujel, the other being cruelly bended behind her back as she wailed. 
Brixujel reached out for his sisters arm too, but when he grabbed her hand, it was fading with the shadow, and they were both turning to mist, blowing away with the gentle breeze coming from his window. 
"Molly!   " He screached. 
"Brixujel!  " She cried.
"MOLLY!  "
"BRIXUJEL!  " 
Brixujel cried out, and shouted, and even if she replied, she really wasn't there. 
The next thing he knew, the mist had turned to dust, and was pilling over everything in the room.  He slowly rose from his position of sitting, and whiped the dust off of himself.  Memories of the event that was just before him evaded his mind, making him want to cry.  He pushed those to the side, not wanting to think of it. 
Rushing into the livingroom, he grabbed the phone.
"Xikven, I need your help, " he bubbered.
"Big time.  "
