The hero, Hikaru, is a boy full with energy, dynamics and modern. Generally, he wears relaxed clothing like T-Shirts superposed on his sweatshirts and long Bermuda shorts. On some of his T-Shirts there is a five, which is pronounced "Go" in Japan. He only begins to wear costumes and ties when he becomes professional (moreover it doesn't fit him very well…).

During the first 5 volumes, Hikaru does not change less than 20 times of clothing (Yes ! we have counted!)

He changes clothing every days and he owns a large variety of clothes which also change according to seasons (like any normal person). But where the manga is really well thought, it is that after several chapters, Hikaru can wear trousers or t-Shirts he had already worn before. Very realistic!
