A sample of a cover song by Ikasan
"Bad ∞ End ∞ Night", composed by HitoshizukuP and Yama△

Ikasan (いかさん) is fairly new, having started in mid-2011. She used to be known mostly as a namanushi, but is now 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 has to make a conscious effort to produce a natural-sounding female voice. Her female tone has improved noticeably since her debut, and she regularly uses both voices to duet with herself. It is dubbed "takosan" (octopus) as a contrast to her regular voice, and can be heard most clearly in her "Love is an Open Door"Nv and "How-to Sekai Seifuku"Nv.

Her most popular cover is "Love is an Open Door"Nv, with over 375K views and 17K Mylists as of September 2014.

She rarely does collabs, but when she does, it's usually with similarly deep-voiced girls.

She is usually depicted with short black or brown hair, and sometimes with a squid clip in her hair.
