These two are from the manga Red River. It is about a teenage girl who gets sucked into the ancient past because of an evil queen who wants to use her as sacrifice to kill all the potential Kings. She does this to get her son a chance to hold the power to throne. Yuri ends up meeting a prince who uses all his power to protect her. He also tries to help her go back to her modern Japan.
Anyway, it's FREAKIN AWESOME!
