Appearance
Nikaidou is usually seen wearing his school uniform. Unlike other male students, he unbuttons his collars, revealing a red shirt underneath. He has short and messy brown hair. He also has much darker skin than the rest of his friends.

While wearing summer uniform, however, he doesn't wear red shirt.

History
Nikaidou, alongside Momota, first appeared as boys who got in fight with another boys from other school. Luckily, Mana quickly stopped their quarrel. Later, him and Momota were shown outside the tower's entrance. He lamented on how the line is too long, and wished to be a crab so he could cut the lines. Shortly after, Mana noticed him and waving at them to wait in line. Nikaidou, knowing that they couldn't deny Mana, followed her order and went behind her and Rikka. When the Crab Selfish attacked, Nikaidou was surprised and then escaped.

In DDPC02, Nikaidou, alongside Rikka, Momota, Juujou Hiroshi, and Mr Kido, went to see Mana in front of the lift of the entrance. When Mana told them that she was fine, Nikaidou was relieved. The next day, upon hearing Momota's comment on how Mana looked down, Nikaidou replied that it's about time she stopped being so energetic.

Nikaidou and Momota only appeared in DDPC03 during a flashback. Here, he commented that Mana will obviously be the next student council president.

In DDPC09, Nikaidou was surprised when he saw Sharuru, Raquel, and Lance chasing Ai from the classroom's window.

In DDPC12, Nikaidou and Momota saw Saotome Jun's plead to Mana from behind the classroom. Later, some students who looked like them and Juujou were fighting with other students.

In DDPC31, Nikaidou was seen asleep alongside other students of Oogai First Middle School.

In DDPC32, when Mana encouraged the festival commitee members to make the festival "a blast", Nikaidou got annoyed and said that she shouldn't overworked herself. He was surprised when Mana collapsed soon after.

During the festival, he promoted his class' booth alongside Momota and Yashima. Yashima noticed that Nikaidou looked down and asked him to cheer up. When a student lost his balance when climbed the campfire, Nikaidou warned him. After the campfire got damaged, Nikaidou immediately lifted a woodblock to re-arrange it, asking Momota's help beforehand. When Rikka asked him why he did so, he answered that they still have time before the afternoon. Then, he reminded them of Mana's words, that they need to make the festival "a blast". When Mana, Alice, and Aguri arrived at the schoolyard, Nikaidou and other students were working hard to re-arrange the campfire. When the Teacup Selfish attacked, Nikaidou and other students rushed to the campfire and told the Selfish to not touch the campfire. The Selfish ignored their words and attacked them, but the Cures immediately showed up and saved them. Nikaidou asked them who are they, but only Cure Heart replied. After that, Nikaidou and the others cheered the Cures.

During the folk dance, Nikaidou and Momota were seeing the others dancing. Later, Momota pushed him around and he looked annoyed, making the other students laughing at them.

In DDPC47, Nikaidou watched the Cures' battle against Selfish King in Teacher's Room. Later, he and Momota came to aid Jun. Jun thanked them for their help, and told the other citizens that they should help each other in need.

In DDPC48, Nikaidou and the rest of the school were surprised upon hearing Mana's taunt, which revealed her identity. Then, Nikaidou remembered when Cure Heart introduced herself during the school festival, and thought that no wonder she seemed familiar to him. Encouraged by this, Nikaidou rushed towards the window and shouted his encouragement to Mana, telling her that he's always with her. After Selfish King was defeated, Nikaidou came to Mana's side along with Momota, Yashima, and Juujou. Nikaidou then procceed to scold Mana for making him and the others worried.

In DDPC49, Nikaidou ran towards Mana, but was stopped by Sebastian before he could reach her. After the Proto Selfish took the Cures down for the first time, he was seen alongside Momota and Juujou on top of a temple. When Juujou asked him to run somewhere safe, he replied that he'd rather stay there and watch the Cures fight, as he believed that it's the end for them if the Cures lost. As he sat down, he unconsciously told Mana to not die. During the epilogue, he and Momota were seen walking to the school together.
