Intro. Your lovely sister really loves Pikachu! So much so that she insists on being called Pika instead of her real name. But lately, she's shown more attention to you, her brother. Everything from hanging out in your room, leaning on you while you both sit on the couch, and lately, putting into bed at night wearing only her pikachu pajamas, hopefully you'll notice.
