Aside from regular name calls and lyric calls, there are also situations where fans insert the member's catchphrase in front of the call. You've probably heard "Egao ga ichiban, Reni-chan!" before! This is what Japanese Mononofu call an 8-character call (8文字コール), because there's just enough room for 8 syllables in the call. E-ga-o ga i-chi-ba-n is technically 8!
Below are the different 8-character calls for each member, translations, the situations they are used in, and the recent trends. Some are more appropriate than others in certain songs, so I've listed them first on the respective song page. These calls are also generally less well-known (and less widely-used) than the primary calls, so try and feel out the crowd.
It's all unofficial, so there's quite a bit of variation among the audience in terms of popularity levels. Reni's, Shiori's, and Momoka's calls are mainly steady, while Kanako and Ahrin have quite a few. Just pick whichever one you like - the core concept of a Momoclo concert is to have fun!
- "Ore-ra ga sasaeru!" Kanako!
(Most common. Originally mainly used in words of the mind. Created from the line "at times I use you as my source of support", it stuck with a lot of fans and spread in usage.)
"We will support you" Kanako!
- "Koe wo kikasete" Kanako!
(A little uncommon.)
"Let us hear your voice" Kanako!
- "Ore-ra no taiyou" Kanako!
"Our sun" Kanako!
(A lot of people think that Kanako's fine without an 8-character call!)
- "Minna no imouto" Shiorin!
(Outdated now that Shiorin has changed her catchphrase to "Momoclo's Young Ace", but no one's settled on a new one yet.)
"Everyone's little sister" Shiorin!
- "Minna no wakadaishou" Shiorin!
("Official" new catchphrase. Will it stick?)
"Everyone's young ace" Shiorin!
- "Zettai aidoru" Aarin!
"Absolute idol" Ahrin!
- "Aarin! Aarin!" Aarin!
"Ahrin! Ahrin!" Ahrin!
- "Suki, suki daisuki!" Aarin!
"Love, love, love you" Ahrin!
- "Hako-iri aidoru" Aarin!
"Sheltered idol" Ahrin!
- "Genki de ariyasu" Momoka!
"Doing good" Momoka!
- "Chiisa na kyojin no" Momoka!
(Not very common, but somewhat official?)
"The little giant" Momoka!
- "Egao ga ichiban!" Reni-chan!
(This is it.)
"Number-one smile!" Reni-chan!
- "Biribiri kanden" Reni-chan!
(Some people use this in Z Densetsu.)
"Zapping electric shock" Reni-chan!
