Ikasan (γγγγ) is fairly new, having started in mid-2011. She is known mostly as a namanushi, but is also prominent as an utaite. She is a ryouseirui, but unlike most other female ryouseirui, her natural voice is nearly identical to that of a grown man's, and she finds it difficult to sing in a natural-sounding female voice. However, her female tone has improved noticeably since her debut. It is dubbed "takosan" (octopus) as a contrast to her regular voice, and can be heard most clearly in her cover of "Otsukimi Recital" Read more on Last.fm
