However, this is later revealed to be incorrect and she is indeed the daughter of Lena Sayers, the previous user of the gem. She forms a contract with Mashiro as a Coral Otome, and later as Meister Otome. In the sequel, she is shown to be able to channel a "Zwei" form of a Robe, thought to be the true form, which allows for immense strength. She frequently quotes sayings from her grandmother, who raised her. In the manga, Arika's role is somewhat reduced into that of a comedy sidekick, in favor of a different leading character. Arika has a childish innocence about her and a naivety that is taken advantage of by some of the other characters. She can be socially awkward, due to lack of contact with people while she was growing up. In battle she is a natural, quickly adapting to situations and never giving up. This gives her an advantage over the other Otome and allows her to surpass the other students in her class. • : A main character of

She shows a love for technology and is under the tutelage of Yohko. • : She is Coral No. 2 and a room attendant for Chie. On the outside she acts normal but is jealous of Arika's and Shizuru's relationship.

In the Zwei series, she is no longer an Otome and chooses to become a presidential candidate for Aries. • : Lilie is a member of Arika's class and one of Chie's room attendants.

She has yet to lose her virginity in Zwei, as she is still able to call forth her materialisation. • : Chie is Pearl number two and a member of the Trias. She is very boyish and often carries a blue rose around. :She is from the Aries Republic and seems to have some relationship with Aoi, paralleling their relationship from the first series. Chie remains calm and tries to help out whenever she can and balances out Shiho's aggressive behavior when dealing with student discipline. In episode 15 she tells Nao that she met Aoi when she started attending Garderobe. When Nao's gang was about to torture Miya's gang for attempting to rape Arika, Chie and Aoi showed up on the scene in which both Nao and Chie later took in Miya to interrogate. Later on, she said she was out on a date. When Mashiro was feeling depressed due to Takumi's words, Chie suggested to Aoi to bring in Arika to cheer her up which works and pulls both out of their depression. Chie was also aware that Tomoe Marguerite was involved in numerous plots to take out Arika Yumemiya but rather than report Tomoe she orders her to stop it. Despite knowing of the fact that Erstin Ho was injured during another plot, Chie kept silent about it for unknown reasons.

manga version of My-Otome, Chie's role is far smaller. Without the antagonism of Tomoe or the existence of the Valkyries, both of which were major plot points in which her anime counterpart had a part to play, she becomes mainly a background character. Her importance is further downplayed by the fact that she still uses the standard Pearl Robe whereas her fellow members of the Trias use Meister-level Robes. She is still seen in the "group shot" of the Materialised Otome ready to do battle, though, and is seen briefly "dealing with" Shiho Munakata, offering a "taste of a real oneesama" as the Otome fight with the resurrected HiMEs, to the embarrassment of both Shiho Munakata and Shiho Huit. • : Shiho is Pearl number three and the last member of the Trias.
