I've been half-following her blog ever since, but she hasn't really had another role until this year. Now, however, she has suddenly appeared as Kuroyuki-hime ("Snow Black"), one of the leads in the very popular new anime Accel World.
Will this launch her as a seiyuu? I like her work here, but 2channel doesn't. The argument in her thread is between seiyuu otaku who find her amateurish, and fans who say she is doing a good job. She is not a highly skilled and polished seiyuu, with great variety in her voice, but for me she is giving the character a good presence.
Misawa is from Yamanashi prefecture, in the mountains just west of Tokyo. She won the grand prize in the 2008 Kadokawa x Up-Front Style idol seiyuu audition. Most of her work since then has been idol-related, rather than as a seiyuu. Now she is 19 and beginning her second year of university. She is with the agency Style Cube, the same agency as Ogura Yui and Ishihara Kaori.
