Kannaduki Iku is the male representative for the month of October. He is an idol under Tsukino Talent Production, and is a member of the unit Procellarum. His producer is takamatt, and he is voiced by Ono Kensho.


Iku is a fair-skinned young male with short brown hair and brown eyes. Initially one of the mid-heights among the 12 idols, he, together with Six Gravity's Kisaragi Koi, have experienced the greatest height increase since their debut.[1]


Iku is lively, and athletic, preferring to be constantly in motion compared to staying still. He is the type who always looks forward and remains aware of those around him. He also exudes a natural aura of masculinity.[2]

Compared to the other idols, Iku comes from a comparatively normal family. He possess a normal type of common sense, making him and Haduki You the ones in charge of throwing retorts at his fellow idols' antics.[2][3]

Due to being the only member who decided to keep participating in clubs, as well as having to commute a lot, he ends up being very busy, but manages his time quite professionally.[3][1]


Iku comes from a relatively normal family from Hyogo Prefecture, Japan. Although he was born and grew up in Hyogo, he went to a high school in Osaka that was famous for their club activities.[4]

His is a family of four, consisting of him, his parents, and a sister who is one year older than him. They attended the same high school and often got mistaken as twins because they resembled each other so much.[3][4][5]

During the national athletic meet held in Tokyo, where he was due to participate in the track-and-field events, he had been scouted by a (questionable) producer.[6][7]

He got accepted into high school through sports recommendation. The university that he attends to also accepted him via sports recommendation.[8][9]


Minaduki RuiEdit

Iku initially had a hard time trying to become closer to Rui, the two have become close friends, to the point where Rui now addresses Iku by his nickname, "Ikkun". Iku didn't know the details of Rui's family situation, and was thinking that he would let it be until Rui himself feels like telling him about it.[3][4]
