After fighting off an attack by Zoisite, Rei's grandfather takes on an apprentice and begins acting strangely.


Grandpa Hino was outside on the roof of the shrine looking at the moon when Zoisite appeared and tried to extract a Rainbow Crystal from him. However, Grandpa Hino blasted Zoisite, who was unprepared, and knocked him off the roof where he was quickly attacked by crows. When Rei went to her grandfather's aid, Zoisite vanished.

Meanwhile, a drunk man, who had been sleeping on the shrine steps, awoke to an irritated Rei who demanded to know his identity. He revealed himself as Yuichiro Kumada and asked to become Grandfather Hino's apprentice, as he had instantly fallen in love with Rei.

Later, Rei told everyone that her grandfather had become a little strange. She was going around trying to train Yuichiro doing stupid things like swinging from trees. Yuichiro was seriously trying to follow his training but to no avail. Because of his actions, Rei told her grandfather to act more seriously because they would lose trust in their shrine.

Later Yuichiro told Rei that it was autumn, so it might be just the season causing the weirdness in her grandfather. Rei laughed and thanked Yuichiro. Usagi was watching Rei and Yuichiro from behind a tree. She wanted to make Rei and Yuichiro closer. Luna told her that it might make things worse. Then, Usagi transformed herself into a fortune teller. Luna got very disappointed in Usagi for using the transformation pen for that purpose. Usagi (as the fortune teller) went to Rei and Yuuichirou and said that if they kissed each other right there, they would fall in love with each other. Rei goes mad and said, "Let's go," to Yuichiro. Then Rei went to Usagi and got mad. She said, "What are you doing? I already have Mamoru." Then as she was leaving, Rei also said, "I'll have nothing to do with you again!"

At home, Usagi was very sad. Usagi was crying on her bed, "Oh no. Rei got mad at me again." Luna said, "Don't worry about it. Rei always gets mad, but she also always forgets pretty quickly. You can make up tomorrow." Usagi said, "But she said that she will have nothing to do with me anymore." Luna replied, "Rei just said that because you did a stupid thing."

Then Luna ate a daifuku mochi. Luna said, "Usagi, this daifuku is very good." [daifuku = Japanese dessert with soft mochi on outside and Anko, sweet bean paste, on the inside] Usagi said, "I can't eat daifuku at a time like this." "But it's very good," Luna said again. Usagi saw Luna eating the daifuku and got drawn toward it. Usagi then ate one too. Usagi said, "Yeah, it is very good." Luna said, "I told you so." Usagi then came up with an idea. "I think I'll bring this to Rei. I'll make up with her with this delicious daifuku. What a good idea." Luna said, "I think you'll just get her angry again." But Usagi said, "It'll be okay." Luna warned Usagi again, "I don't think you should." But Usagi went off.

Yuichiro was thinking about Rei and training hard. Rei was in the bath, thinking about her grandfather. Grandpa Hino was at a fire. Then Zoisite appeared and blasted Grandpa Hino outside. Rei was still in the bath when she felt some bad feelings. Zoisite used the Black Crystal to get the Rainbow Crystal. Tuxedo Mask appeared and knocked the Rainbow Crystal away. Zoisite then turned Grandpa Hino into a youma. The youma attacked Tuxedo Mask. Zoisite grabbed the Rainbow Crystal and went into the forest. Tuxedo Mask went after Zoisite. But Zoisite had vanished.

Yuichiro appeared and saw the youma. Yuichiro ran to Rei's room. Rei was still dressing, and Yuichiro got a peek of Rei from behind. Yuichiro and Rei ran away as the youma appeared. Then they got cornered. Yuichiro got in front of Rei. He said, "Hurry up and escape. I can die for you." Then, Yuichiro attacked the youma, but the youma hit him away. Yuichiro passed out.

Rei found out that the youma was her grandfather. Rei tried to run away. But the youma caught Rei by the neck. Rei told it that if there were some human feelings left, it shouldn't attack her. But it sharpened its claws and tried to punch Rei. Rei ducked in time to avoid getting killed.

Before he could stab Rei again, Usagi appeared. Usagi said, "Don't pick on my cute friend Rei." Usagi transformed into Sailor Moon. Then, Sailor Moon brought out the daifuku. She told Rei that it was very good. Then Luna said, "Stupid! It's not a time to be eating daifuku." Sailor Moon was going to blast the youma with her tiara. But Rei told Sailor Moon that it was her grandfather. When Sailor Moon hesitated, the youma started chasing them. They ran away. Then, Luna told Rei to stop the youma with her anti-ghost sign. When Rei used it the youma stopped. Then Sailor Moon used Moon Healing Escalation and the youma returned to Grandpa Hino.

Makoto and Ami came back to the shrine and met at the bottom of the stairs. Since the danger was now over, they were all eating daifuku. Yuichiro wondered where the youma went. Rei and Usagi tried to pretend that there was no youma. "Maybe you were dreaming." Yuuichirou said, "I don't think it was a dream."

Rei then kissed Yuuichirou, saying Yuichiro was very strong and had a lot of courage. Usagi said that Rei must like Yuichiro. Rei tried to say that she was just trying to be nice because Yuichiro always got scolded by her grandfather. Grandpa Hino said that he wouldn't let Rei marry Yuichiro. They started chasing each other around. Makoto and Ami saw that Usagi and Rei had made up.
