To me Airi has the best chance of remaining a popular Idol after C-ute disbands, she'e easily the most popular member now and has been for a few years. She could decide on a solo career or perhaps do more with Buono!, I think she has a really superb voice and would hate not to hear anything new. Sure Airi may take a mini break after June 12th's final concert, she has been working non-stop for well over a decade now like all the members have.
On April 12th Airi will be turning 23, for a long time there was a photobook released around that date but that hasn't happened for the last two years. However there will be one this year and probably her final solo one as a member of C-ute. The PB is titled "Eternity" and is coming out on March 31st. It'll consist of many 'greatest hits' pics since 2010 but there's also going to be plenty of new pics. There will also be an event for the book put on by Rakuten and there will be a fan signing session with a thousand people being invited, probably for those that pre-ordered the book. There's also a calendar for her coming out that covers the period from April 1st to March 31, 2018.
Airi does much more than just sing with C-ute, she has her own radio show and appears in more mags than all the other members do combined. Would like to see her in more dramas or films, everything I've seen her in has been enjoyable. Speaking of mags here's a brand new one which is from the April 7th issue of Young Gangan.
Ray is a magazine which Airi appears in monthly. She also does a special feature at their site called "Airi's Five Days". That feature will be stopping at the end of March but she'll be doing other work for them, have six pics each here from the March 3rd and 10th weekly features.
Didn't think this was going to end up being a big post but was wrong with that thought, that's a good thing as she's really been growing on me these last few months. Airi has been doing a radio show since last July titled "Airi's Potion", here are some blog pics from the show for the last two weeks and it broadcasts on Wednesdays.
Subbed videos for C-ute's final single are now on YT, will have them in future C-ute posts. Have four screenshots each here of Airi from the "To Tomorrow" and "The Curtain Rises" videos.
