Koi ga Saku Kisetsu CD The Cinderella Girls 6th General Election CD, released in December 2017. Hiromi features on the main track, which is reserved for the top 3 of each category. It's her debut work, so I bought three copies.
Cinderella Master 049 Rakuen CD Hiromi's solo debut, released in April 2018! Along with her solo, she's featured on an original drama track, and some of her Mobamas lines are reprinted as a bonus track. It was sold in a bundle with CM 050 and CM 051. I bought three copies again, but sold off all but two of the CM 049 discs.
Cinderella Master 049-051 In-Store CD A CD sent by Columbia to stores, for use in promoting the CM 049-051 set. Probably one of the rarest things I own.
Master Seasons Spring CD Released in April 2018. Hiromi is featured in one of the group songs, HARURUNRUN.
Starlight Master 19 With Love CD Released in July 2018. Hiromi is featured on the C-side of the CD, always! This song was originally sung by the top 5 overall in the 6th Election, but the Deresute event had the five newly-voiced girls perform it instead. This song is a massive tearjerker, especially if you've spent a long time invested in a certain idol. It's a targetted attack.
Cinderella Girls Theater (Gekijou) 3rd Season Part 2 BD Saya Aizawa is featured on the bonus CD, along with Momoka's VA! Hiromi also appears on the cover, and some of her costumes are featured in the booklet.
Master Seasons Spring Solo Collection CD The only way to make a group song with Hiromi better is to release a solo version. This CD was a 6th live exclusive, but evetually the price dipped on Surugaya. The cover is really pretty and shimmery!
Starlight Master 26 Bi ni Iri Sai o Ugatsu CD Released in February 2019. Hiromi is featured on the C-side of the CD, Aikurushii ~SS3A Remix~. It's a surprisingly bitter song.
Starlight Master for the Next! 02 Step & Skip CD Released in November 2019. Hiromi is finally on the A-side, singing Step & Skip with Hotaru and Nono! New to SMFTN, the solo versions of the song are also included, meaning that Hiromi gets two tracks. The lyrics express each member's insecurities, and the bridge calls back to each of their solo songs... it's really perfect for them.
Cinderella Girls 7th LIVE TOUR Special 3chord♪ Comical Pops! SPECIAL LIVE ALBUM Released in 2020, this CD is a bonus for ordering the Comical Pops! BD from Columbia's store. There are live albums for each recent BD, but this is the first one that has Saya Aizawa on it! She's featured on the live version of Kyun・Kyun・Max.
LITTLE STARS EXTRA! Sing the Prologue♪ CD Released in August 2020. The title track was used as the first ending to Cinderella Girls Gekijou Season 5! It was the first Gekijou ending to receive a full animated ending instead of just a 30-second ending, but it sacrificed having a 3D dance in the mobile game. Similarly, the CD has solo songs for some idols that sorely need them, but it sacrifices having solo tracks for the main song... so there's only one song on the CD with Hiromi, even though she's on the cover. It's a cute song though, so I can't be too salty.
The Idolm@ster Cinderella Girls -Barrel Org@n Arrangement master 05- "One Steps" A doujin CD released by product-EDW in 2019. Track 2 is a remix of Rakuen for the barrel organ. It has an odd circus-y sound to it. The case is really thin, so it still fits on my stuffed CD shelf.
The Idolm@ster Cinderella Girls -Barrel Org@n Arrangement master 07- "trio" A doujin CD released by product-EDW in 2020. This time, Track 1 is a remix of Step & Skip for the barrel organ. I'm pretty sure I have this track downloaded, but the cover has Hiromi on it this time, so I still bought it...
GBNS & Mezase Kirakira Model Idol Challenge EP A doujin CD released by Positive Records in 2020. Rather than a remix, this CD has original image songs for a variety of idols! Hiromi's song on the album is Bracelet wa Barairo, a cute classic idol-ish song.
SS3A Live Sound Booth BD The live recording of SS3A, Saya Aizawa's first major live portraying Hiromi! The set includes 3 discs, with Day 1 and 2, along with a backstage digest. Sayaan was featured on both days.
Cinderella Girls 6th LIVE MERRY-GO-ROUNDOME @ NAGOYA DOME BD The live recording of CG 6th, the annual CG live for 2018! I bought it secondhand, so the box is damaged along the bottom, but it's hard to see unless you know where to look. The set includes 5 discs, with Day 1 and 2, along with a backstage digest. Saayan was featured on the second day, and appears on discs 3, 4, and 5.
Cinderella Girls 7th LIVE TOUR Special 3chord♪ Comical Pops! BD The live recording of CG 7th, the annual CG live for 2019! The set includes 5 discs, with Day 1 and 2, along with a backstage digest. Sayaan was featured on both days. It shipped out mere days before EMS service stopped for the USA, but somehow arrived without incident a few months later. Comical Pops has the weakest gimmick, in my opinion ("skits" compared to "cool dance numbers" and "a live band") but the live feels cute and well put-together, so I really enjoyed watching it!
