Prompt: "Astolfo being summoned as Sakura's servant. He uses his inescapable net Noble Phantasm (Vulcano Cagliorante) to contain Zouken, then grabs Sakura by the hand and whisks her off on a date across Fuyuki that leaves her smiling but also flustered and overwhelmed by the sudden change of circumstance" — Yuki.
She loved candy. Sakura adored munching on little sweets: sugar pops, gummies, everything Astolfo could get out of a candy store and more. His Master had so rarely had the chance to be a child that he relished in giving her that opportunity again.
He had to say, though—the part where she started eating people was unexpected.
"I'm a monster."
She sat on the bed that her boyfriend—was he really? he never seemed to make any moves—provided for her, curled in a ball.
"I don't see anything scary about you," Astolfo said with muted cheer. He hoped that it would help her somehow.
It didn't.
"Rider, I... I killed someone." She looked at him with teary eyes, still blurred in purple. "I... oh God, I'm going to be sick."
"No, no, not here."
Again, he had to take her to the bathroom and help her dry heave. No, it wasn't pretty, but nor was what she did to all those people. It didn't bother him.
"I... I want to..."
"No ,you don't." He didn't need her to finish that sentence to understand her intent. "Or maybe it's better to say that you shouldn't ask for that."
"How can you bear to even look at me?"
"Well, it's easy. I keep my eyes open and stare." Astolfo forced his eyelids open with his fingers. "See? Like this."
"Stop it... just... stop..."
"Sorry." He wrapped his arms around her. "Monsters don't feel regret, you know?"
"But they love being monsters, don't they? And I loved doing that. They... oh God, they were... they tasted good."
Another two minutes to help her deal with the acid reflux.
"You'll get better. I promise."
Astolfo was an expert in miracle-making. He'd help her out. Whether that meant that she would become good or bad in the end, it didn't matter. He'd make sure she was happy.
