Ojousama no Untenshu

From Omari's Sister: "It is the Taisho Era at a certain girl's school. There one young lady embodies the ambition and is the envy of every girl. The crimson ribbon adorning her marks her as the top student. She is none other than Yoshimura Sayaka. Always at her side is the chauffeur her family employs, Narutaki Shinobu. Are the two in love as rumored amongst the female student body!?" Note: Untranslated one-shot from the first volume—"Ruka to Touzoku (Ruka and the Thief)"
