He goes along

Kazuma decided to go along with her. "I'll come with you, so you don't need to drag me."

"So where are we going?" Kazuma asked as he followed along. "Somewhere we can be alone," Satsuki answered quietly. As they walked through the hallway, Kazuma noticed that Satsuki was not only avoiding looking at girls, but she was staying away from them. They walked through the building and headed outside. Satsuki lead Kazuma to one of the storage sheds outsides. Thankfully, the shed was unlocked, so they went into the shed. "Sorry for dragging you out here," Satsuki said as Kazuma closed the door. "but I really need your help."

"It's fine," Kazuma said. "You looked troubled. So what's wrong?"

"Well, you see...," she began. "My father is a vampire..." Kazuma was a little surprised by this. "It's not shocking," Satsuki said on seeing Kazuma's reaction. "You've seen my fangs before." That's right, Kazuma thought. Satsuki always had these fang teeth for as long as he could remember.

"Because of my vampire side, I have a strong desire to drink blood."

"So you need blood?" he asked. "Is that why you brought me here?"

"No, it's not that simple." Satsuki said nervously. "I can only drink the blood of other girls. And being back at school, being around all the girls here makes it harder to resist."

"Then what do you want me to do?" Kazuma asked in confusion. Does she want me to help her get blood from a girl?

"There might be another way to satisfy this desire," Satsuki said, her face getting redder by the second. "My mother...is a...succubus."

Kazuma's face started to turn red as he realized what she might want to ask him for.
