After the death of her parents, Mei discovers that she is the successor to the rich and powerful family and must leave her humble family restaurant, attend a girls academy and accept her new butler, who wants to do everything for her.
Rihito notices that Mei looks strange. Mei started avoiding humans. One of the causes was that Lucia was not telling Mei that she was actually a member of the Hongo family. Lucia's real name is Shiori Hongo. It is said that she was adopted as a foster daughter after Mei's father, Shutaro, left the Hongo family, a distant relative of the Hongo family. Mei, who was taught by Lucia's butler Shinobu, can't hide her surprise.
Rihito headed to a certain place without witnessing the duel between Mei and Izumi. Shinobu, who appears in front of such a man, says that he can no longer serve Mei. Shinobu has already taken steps to help Mei lose in this duel. Still, he believed in Mei's victory and didn't doubt it. Around the same time, the duel between Mei and Izumi was about to begin at the Saint Lucia Girls' Academy. This duel is a treasure hunt. It was to find a treasure chest hidden somewhere in the school. The treasure chest is said to contain what Izumi's butler Kiba holds dear.
The butler exchange was canceled and Rihito returned to Mei for the first time in a long time. However, there was no Mei in Yin's bedroom. Around that time, Mei and Swordsman were kidnapped by Tami and were in the old western-style building "Timeless Hall" deep in the forest. Tami tells Mei and the swordsman that she can't swallow the situation that they will get rid of you for Lucia. It is said that Tami did all the things that caused the men to attack Mei during the duel with Izumi and scatter the photos of Mei and the man hugging. The man was searching for Mei with the help of Mei's classmates like Izumi and Rika and her butlers. Tami's butler Kanda notices that not only Mei and the swordsman, but also Tami's appearance. In the hallway, Mei and the swordsman were surrounded by men who appeared at Tami's signal.
When Mei's parents die in an accident her Grandfather steps in and sends her to the prestigious school St. Lucia, with a butler by her side Mei must first try and adapt to the school by winning a cooking contest...
Rihito and Mei visit the director of the Girls' Academy of Santa Lucia, Rose. After overcoming the two-week provisional enrollment period, Mei was officially admitted to the St. Lucia Girls Academy. As proof of that, Rose presented Mei with a golden bell, and as a celebration of admission, she placed a little green gem called a star in the recess on the side of the bell.
Rihito and Mei are upset by Lucia's words that suddenly reached the class. Lucia is said to have become Mei's classmate and her friends as of today. Lucia's butler, Osamu Mukai, reveals to everyone that Mei, like Lucia, is a candidate for the successor of the Hongo family, as if to take revenge on her. Furthermore, Shinobu even talks about the fact that he was serving Lucia until a year ago. The swordsman, who knew that Lucia was stalking Mei to get her back, enraged her. It is said that he is the man who afflicts Mei.
A photo of Rihito and Mei hugging was posted in the classroom. Confusion spread between Rika and Rin who saw the image. In St. Lucia Jogakuen, romance between a young woman and a butler is forbidden and, if discovered, she will be expelled from the school. The swordsman grabbed the man, not to do anything foolish. Izumi appeared there and told the man and Mei to refrain from doing so until the facts are investigated. Soon, due to insufficient evidence, Mei's disposition will be lifted. At that time, a notice is issued for each class of the St. Lucia Girls Academy. It was to exchange butlers in class. In response, a butler decides by lottery in Mei's class. As a result, Mei's butler will be the swordsman.
