He’s only sixteen, but Kurenai Shinkurou is already both a martial arts master and professional mediator with a long track record of resolving disputes. Yet when given the assignment on protecting Murasaki Kuhoin, Kurenai may have been dealt more than he can handle. Even though she is only seven, her very rich and extremely powerful family are guaranteed to take this job directly into the danger zone.
Shinkuro Kurenai is approached with an assignment to protect a mysterious girl named Murasaki Kuhoin. Despite having concerns for leaving Murasaki alone, Shinkuro goes to school. However, when he returns, Murasaki cannot be found...
A worried Shinkuro constantly calls the missing Murasaki who is not answering her phone. When he finally gets through, the voice on the other end is not Murasaki's.
While exploring her new school, Murasaki meets Yuno and quickly becomes suspicious of her. Meanwhile, Shinkuro takes on a new assignment.
Murasaki follows Shinkuro to his new job, where she is promptly captured. Shinkuro negotiates tenaciously, but the two end up in a desperate situation that finds Murasaki unconscious.
On a Sunday afternoon, Murasaki is engrossed by the ferocity with which Shinkuro trains.
The residents of Samidareso are asked to volunteer for a musical that will be performed at the local festival. Shinkuro continuously declines, but Tamaki and the others confirm their participation anyway.
Tamaki passionately describes to Murasaki about how to please a woman. In order for her to get a better understanding, she takes Murasaki to her college where a new side of Tamaki is revealed.
Murasaki’s eyes sparkle as she makes her first visit to a temple. They all spend a peaceful time taking pictures and exploring. However, behind the shadows are mysterious men watching Murasaki’s actions very carefully…
Realizing that he is making an enemy out of the Kuhoin Clan, Shinkuro loses his confidence to continue being Murasaki’s bodyguard. Meanwhile, Samidareso is attacked by an unknown enemy!
Shinkuro can’t hide his guilt about Murasaki's capture. Yayoi begins to tell Shinkuro about a mistake she had made on her job, and gives him advice to forget about the Kuhoins and Murasaki right away. Even after hearing that, Shinkuro can’t shake it off, and so he tries what he can to refresh his mind.
Shinkuro begins his break-in to the Kuhoin mansion with Benika and Yayoi. Defeating countless guards that attack one after the other, Shinkuro and the group make their way to the back where Murasaki is being held captive.
Shinkuro and his cohorts battle it out with the overwhelmingly powerful Lin. Renjo tries to drive Shinkuro’s group out of the mansion. However, Shinkuro attempts to break back in by himself just to have one last word with Murasaki.
