The series centers on Mirai Momoyama and Emo Moegi, two childhood friends who aspire to be idols. In order to do this, they use the Pri☆Chan System, a system used by celebrities and companies to upload and broadcast content that is popular among young girls, to produce their own Internet channels.
- Absentee Actor: Meltic StAr is nowhere to be seen in episode 49.
- Catchphrase: Mirai's is "Kiratto!" ("sparkling"), Emo often uses "Emoi" (very roughly translating to "good vibes").
- Colorful Theme Naming: The main characters' family names have the kanji for their hair color, with Momoyama (Pink) and Akagi (Red) being two examples.
- Goldfish Poop Gang: Oshama Tricks, to the point that characters often misspeak their name as 'Ojama Tricks' (Nuisance Tricks). They make frequent appearances to try and steal candy and win by cheating, but their plans either don't work out or get thwarted before any major damage occurs.
- Gratuitous English: Mel uses this a lot.
- Idiosyncratic Episode Naming: In season 1, Every episode's title ends with みた ("mita") in Japanese, which can be translated into English as, "We Tried (blank)", this is dropped in season 2 and instead every episode's title ends with Dia saying "~da-mon!".
- Instant Web Hit: Plays a major role in the plot of the show. If any video on Pri☆Chan becomes this, a sparkling message that says "READY FOR LIVE" will appear on screen, enabling the person who produced the day's top video to perform.
- Lucky Charms Title: The title has a star in it so.....
- "On the Next Episode of..." Catchphrase: Join hands and expand our follower world!! Our fabulous show's live on the air!!
- In season 2, Aim to be a Jewel Idol! The Sparkling Jewels shine in Pri☆Chan! ~da-mon!
