Iason Inabi first met Umi Sonoda on a hotel café on FanonLand Hotel. Intrested on her, he attempts to talk to her. Umi however, was busy talking with the other Muse members. Slightly annoyed, Iason pokes Umi's back, who turns towards Iason. Iason then intrdouces himself to Umi Sonoda, who then indtrouces herself to Iason. Iason asks Umi what her first name meant, she responded with that her name meant "Water".
