Rina Nagako (ながこ りな Nagako Rina) is the manager of Ido. Her preferred brand is Baby Monster and she is a cool type idol.


Rina has black hair reaching her shoulders and has red eyes. She is always seen wearing the China Rock Coord.


Rina is very serious about being an idol which is why if someone who isn't serious about it wants to become one, she gets very angry. She was once a popular idol named Reika Natsumi (A lovely type idol who uses Marinette Mu with a cheerful personality) but quit being an idol due to her fans thinking she wasn't unique anymore. She became an idol again after becoming Rina Nagako, the complete opposite of Reika.


  • Yuri Aido - Rina treats her as the leader although she doesn't respect her as much as the others. They are part of Ido together.
  • Sakura Eri - They knew each other when they were children. When Rina was Reika they wanted to become idols together. Their friendship isn't as strong as it used to be but they are still very close friends. They are part of Ido together.
  • Yurina Tomoko - Rina doesn't like Yurina that much, thinking she is childish and irritating. But they have a close friendship. They are part of Ido together.
