Rinko using Ruby's Jewel Charm to Awaken her for the first time

Rinko's Magical Skills are very reliant on magical items she obtains from the magicians to awaken Jewelpets. Using Ruby's Jewel Charm, she and Ruby can officially awaken a Jewelpet from its sleeping state using the magical phrase "Puri Puri Pururin Purirism! Open! Jewel Heart!" (プリプリ・プルリン・プリリズム・オープン・ジュエル・ハート Puripuri pururin puririzumu ōpun jueru hāto?). In episode 14, both Ruby and Rinko use the Jewel Pocketbook to awaken Jewelpets and also find the lost Jewel Charms on earth. Also, she uses the pocketbook to find Diana's location.

After she obtains the Jewel Stick, Rinko finally evolved into a full pledged magician, thought she had problems on casting her own magic. However, she can still use the wand to awaken the Jewelpets from their Jewel Charm State, as well as casting magic.


First encounter with Ruby

In the beginning of the series, Rinko is having problems with herself after being chosen to give a speech to the new students, seeing that she could mess up. Her friend Minami tries to cheer her upon that time and said everything will be ok. That night after the Jewel Charms were scattered on Earth, Rinko herself saw Ruby's Jewel Charm landed in her drinking glass and phoned Minami about it. The next day, she and her friend goes to the jewelry store to examine the jewel, but then got into a jewelry store robbery. They were saved by a man named Keigo Tatewaki and saw the red jewel Rinko has. He then explained to them that he was working for a special organization which is linked to the great magicians of Jewel Land and told them about the Jewelpets and also told them that all of them were scattered all over town. Rinko accepted the offer on gather all the Jewelpets back to Jewel Land and awakened Ruby using the Jewel Pocketbook.

In the first time Ruby cast her Magic, she said everything will be alright tomorrow for the speech, and in a series of unlucky events, she somehow got the courage to face the crowd and welcome the new students.

Gathering the group

After that time, Rinko and Minami both started their search for the charms on Earth. For their first search, they encountered Garnet's Jewel Charm and awaken her in her Charm state. But when Garnet runs away and they decided to find where she is, Rinko convinced her while climbing up, saying that Minami once protected her when she was a kindergarderner and made her happy. Not knowing she still has fear of heights, Rinko fainted and Ruby came to save her. In persuasion to make Garnet use her magic, Minami took her back to her home and she sees Minami's room covered in pink. In agreement, Garnet uses her magic and Miyamato comes and eats okonomiyaki, agreeing to join the group.

In another search, Rinko learned that Aoi is leaving Japan for good and is going to Britain to study. Before that day, Rinko and the two Jewelpets go to her mansion and had a little talk with Aoi, convincing her that she got friends and Rinko wanted to be her friend before she leaves. Thought Aoi was saddened when she found out that Ruby and Garnet are spying on her room after they saw Sapphie's Jewel Charm. The next day, the ground rushed to the Airport and tries to convince her to stay. With no options left, both her and Ruby awakened Sapphie from her Jewel Charm state and convinced her that Sapphie's magic can guarantee her to make her have friends. After she agrees, Sapphie cast her magic and hilarity ensures, thought it made Aoi happy and finally leaves Japan. However the next day, she returned to school and decided to stay with them and agreeing to search for the lost Jewelpets.

Meeting Akira

At first, they were sworn enemies, and couldn't get along. He even makes fun of her pronouncing "Orange" incorrectly. As the show went on, their feelings became more apparent, and they blush often. However, when Andy(Dian) came along, she starts falling for him because he's a prince. She believed Andy so much that when Keigo Tatewaki did all the research and confirmed he wasn't a real prince, she didn't listen, even when Akira confessed his feelings to her, instead rejects him, and says he's harsh and nothing like a gentleman. After Rinko gets tricked by Andy/Dian, she becomes brainwashed/controlled to marry Andy, but she still has some awareness in her, so hesitated awhile before letting him put the ring on. After that, she was asked who her prince is since hesitated, and she chose Akira. They then fall while Rinko is still brainwashed/controlled. Akira, remembering Garnet saying that a kiss will awake the princess, kissed her and she woke up. After this arc, their feelings become so apparent that even Labra knew. In the end, they both confessed their love for each other and were about to kiss, until Ruby interrupted them.
