Itsuki Akiba

Loud, reckless, and shameless, and seems to be a complete opposite of Iori, including her affinity towards wearing boyish clothing and having a short haircut. Itsuki and Ichitaka had been friends since grade school, with Itsuki (although a year younger) often being an emotional coach to Ichitaka, particularly regarding girls. The two seemed to become closer than friends in their young life, a relationship that was suddenly interrupted when Itsuki moved away to America four years before the series begins. Just as abruptly, Itsuki returns to Ichitaka's life soon after the series starts, now a fully grown young lady, but still with real feelings for Ichitaka. Halfway through the series, she goes back to America to work with a world-renowned sculptor and is further unseen. After she's gone, she seems to occasionally appear in Ichitaka's mind to scold him during his bouts of self-pity, though these manifestations are really just Ichitaka's subconscious trying to tell him something important.
