The Person I Loved Asked Me to Die in My Sister's Stead manga volume 2 features story by Mizuki Nagano and art by Maki Yamori.

Twenty-three years after becoming guardian of the Predawn Realm, Wisteria is joined by none other than Lord Bright's son! Lloyd seeks the sacred blade, Sartis, and will only return home once he's defeated Wisteria and claimed the sword for himself. Wisteria has agreed to train him, but… why does he want Sartis so badly? As the pair adjust to their roles as master and disciple, Lloyd reflects on his past, and the decisions that led him to this world. If he can master the use of magic, perhaps he can take control of not only the sword, but his own destiny.
