Tadase also explains further the reason of the sudden visit. It was like he said; he was the boy who cried wolf. In the anime, after he leaves Japan to search for his father, Ikuto keeps in touch with Amu, Utau and Tadase. He suddenly looked really sad. She got my mind blown, I feel like I'm gone, Way outta my head, did ya hear wat I said?
Like his father, Ikuto is a skilled violinist. He did that stupid smirk of his, the one that had me going a billion shades of red and acting the exact opposite of 'cool 'n' spicy'.
