Anime; the one thing that gets us closer to each other and brings us together.
All spoilers must be tagged!
For myself:
Nao Touyama (Karen in Kiniro Mosaic, Rin in Yuru Camp, Sakura in Koisuru Asteroid) Inori Minase (Chino in Gochiusa, Aries in Kanata no Astra, Chito in Girls Last Tour) Ayane Sakura (Cocoa in Gochiusa, Rei in Do It Yourself) Saori Hayami (Yor in Spy x Family, Yuzuki in Yorimoi, Yunhua in Kanata no Astra) Kaede Hondo (Maple in Bofuri, Laika in Slime Taoshite, Hikari in Demi-chan)
Hayamin just keeps on giving. Her performance was fantastic in Yorimoi five years ago, and in Spy x Family S2 just last year, and lots of shows in between. Looking forward to more.
You know, the main reason I didn't comment here earlier is that I find it basically impossible to narrow it down to 5. I'm always bumping against MAL's stupid "maximum 10 favorites per category" limit, where to make matters worse they decided that all real people are a single category.
That said: for voice actors, I distinguish between "breadth" (the range of different characters they can convincingly play) and "depth" (the acting skill of portraying a character realistically through a wide range of situations and emotions).
There are some seiyuu that excel at one of these dimensions. E.g. Atsumi Tanezaki has amazing breadth, from Mizore to Vivy to Anya to Futaba. Also Yumiri Hanamori.
Tomoyo Kurosawa has great depth, I don't think there is any other seiyuu who can play a teenage girl as realistically as her, with all the little vocal quirks.
But the greatest have both, breadth and depth. HanaKana, Aki Toyosaki, Nao Touyama, Maaya Sakamoto, Saori Hayami are in that category for me.
Thank you for coming to my TED talk.
I liked Akari Kitou's Chiyoda Momo a lot.
Miyuki Sawashiro apparently as GSNK's Seo Yuzuki and Wotakoi's Koyanagi also is pretty fun.
Of course, Aoyama Yoshino and Suzishirio Sayumi from BTR! and its associated content.
