/jp/ - Otaku Culture

You know, /jp/, I want to be Sakuya. Every time I see her, I think of how much happier I'd be if I were in her position. I don't know where to begin though, so it'll stay a dream.

To answer OP's question, if you go with the fanon depiction of her being in love with Remilia, then just separating the two would be punishment enough, though it would also burden Remi. Otherwise, anything that preys on her loyalty and sense of duty would be far more effective than physical discipline, I think.
