Iona

She is an anthropomorphic avatar of the Sentoku class I-401 submarine whose sole function is to follow Gunzou Chihaya's orders. It is hinted that two years ago she was programmed, placed on stasis and set adrift by Gunzou's father, Shouzou Chihaya, to wait for his son's arrival in order to awaken and have him take command of her.
