>Since Kanae Itou is talked a lot in this general
No, that's just me and anyone else who is nice enough to give me news.
>I looked at her Wiki, and wow, she has really voiced a lot of my favorite characters.
All of her characters are great.
>For some reason she's gotten few roles in the recent years, but I hope she'll get popular soon
The ship has sailed. She will never be on the level of popularity as KanaHana, Aoi, etc. There is no real reason for this, could be a number of things. I do not know how other seiyuus work, I only know how Kanae Itou works, but it could be that she prefers certain jobs. She has a bunch of work on mobile games or apps, having multiple characters for some series. She has been in Pretty Rhythm/PriPara for years, which are year long series. A lot of her roles are from popular franchises and do have multiple games such as SAO, Dynasty Warriors, and the aforementioned Pretty Rhythm. She has albums, she goes touring, and recently started going to more conventions. It is a mystery why she isn't as big as some of her co-stars, but the best part about it is she isn't ever casted to do roles like isekai harem bullcrap or super edgy gorefests. Aside from a couple like Oda Nobuna.
>My favorite role of hers is Ayame!
See, I don't actually play the games and this is what confuses me and which is why I ultimately never thought of her as a Kanae Itou character. She obviously does not have Kanae Itou's voice in the latest games. I just checked that is completely not her voice. So unless she was voiced by Kanae Itou in the early games or the Wiki has it wrong, I am not sure.
