I sadly couldn’t find any roles from magical girl or music animes that Yui Sakakibara is in, so have just have the two characters that were part of the Voiceroid collab, Kotonoha Akane & Aoi!

Tohoku Kiritan & Laala Manaka share the same VA, Himika Akaneya
Tohoku Zunko & Ritsu Tainaka share the same VA, Sato Satomi
Gargoyle/Gako, Miku Maekawa, & Reina Miyama share the same VA, Natsumi Takamori
Genbu, Iori Minase, & Cure Ace share the same VA, Rie Kugimiya (cue Dina fangirling over Iori)

Maeda Toshiie/Inuchiyo, Mia Ageha, and Cure Muse share the same VA, Rumi Ookubo
