Yuu Nikaidou (二階堂 悠, Nikaidō Yū) is a former employee member of Easter. In order to find the Embryo, he joined Seiyo Academy and became in charge of Amu Hinamori's class in the guise of a ditzy but kindhearted teacher.

Appearance and Personality[]

Nikaidou has orange-brown hair and wears glasses. When Yuu is in disguise he talks sweetly and is extremely clumsy. Yuu's normal-self talks seriously. During his time at Easter, he only wore glasses at school. After he left, he began wearing them permanently. He normally wears a white shirt, suit, and tie.

His dream, when he was a child, was to become a robot engineer. However, when his mentor quit thanks to his ill wife and his parents told him they were against the idea, he lost sight of his dream and became a twisted person, though he recovered with help from Amu and Su. He resigned from Easter Company and officially become the teacher in charge of Amu's class.

History[]

When Nikaidou was in elementary school, he was a member of his school's crafts club. He dreamed of becoming a robot professor and greatly admired the teacher in charge of the club, who also dreamed of building a tea-serving robot. From Nikaidou's dream, his Heart's Egg was born.

Some time later, his teacher's wife suddenly fell ill, and was forced to quit his job as a teacher, thus disbanding the craft's club. His parents had been against the idea of him studying robotics, and tried to convince him to give up and study more practical subjects. Nikaidou grew frustrated with this and his lack of success with robotics, accidently breaking his Egg in the process, thus losing his dream of studying robotics.

After he lost his dream, he gradually grew to be a more twisted person and joined Easter in order to find the Embryo. He posed as a substitute homeroom teacher for Amu's homeroom class in search of the Embryo, manipulating students and turning their Eggs into X-Eggs. After Amu and the other Guardians discover his true nature and intentions, he flees the school to forcibly create the Embryo. He steals Amu's Guardian Characters, and though she was able to recover Ran and Miki, Nikaidou was able to keep Su and planned on charging her with the energy of X-Eggs to change her into the Embryo.

Amu is able to find Nikaidou's location in order to free Su. Amu transforms with Su to become Amulet Clover, and purifies Nikaidou's captured X-Eggs by using Remake Honey. This also mends Nikaidou's broken Egg, and he is able to meet his Guardian Character for the first time, though it soon disappeared. Su consoles Nikaidou, saying that if he works on rebuilding himself, his Heart's Egg can be reborn.

After his failure of creating the Embryo and being defeated by Amu, he is fired from Easter. Looking for jobs, he discovers that his elementary school teacher had achieved his dream of making his tea-serving robot. Moved by this and Su's words, he decides to become a proper teacher at Seiyo Academy.

As a proper teacher, he is still clumsy and laidback, but takes his job seriously and appreciates his role as a teacher. At Seiyo Academy, he starts a new crafts club. He is also one of the inspirations for Wakana wanting to become a school teacher.

  • Yukari Sanjo: Yuu and Yukari were once in love, but broke up prior to the series. As revealed in chapter 45, Nikaidou does actually want to get back with Yukari. Yukari does seem to want it too but wants to hold back a little longer because she worries that Utau will get a lot of work so she wants to be available for her. Nikaidou's response to that was that "we'll be going in circles", suggesting that Utau might get promoted to another director/company, thus increasing her and Yukari's workload. In chapter 48, he asked Yukari to marry him, which she agrees.

Friendships[]

  • Amu Hinamori: While in disguise, he called Amu Himamori, as sort of a nickname. Amu also played a part in helping Nikaidou realize his dreams; she became Amulet Clover and restored robots filled with dark energy with Remake Honey. This act, in turn, restored his Heart's Egg.
  • Su: Su was the one who helped Nikaidou realize his childhood dreams to be a robotics professor. She has an admiration for Nikaidou and helps him, examples being cleaning his lab when she was kidnapped, giving him fresh coffee, and hugging the teacher when she can.
