(given name)
saito hikari (hub hikari), of rockman.exe / mega man nt warrior
spoiler for the rockman.exe saito: saito hikari is the unknown name of the protagonist. he is known much better as the one and only rockman.exe, the net navi of hikari netto, the second protagonist. saito (only in the game and manga) is netto’s twin brother, who had died of a disease. his father, yuuichiro hikari, had been unwilling to accept his son’s death, and transferred his entire consciousness to that of a customized network navigator. the two, unlike any pair of netop and netnavi, begin to share a mental link, and have special powers known only to them. unfortunately, in the anime series, saito does not exist, and is just known as rockman.exe, and rockman.exe alone.

second note: there is a slight pun towards their name. being an anime series focusing around that of the internet, they were named netto and saito. noticing this, they are pr-nounced almost exactly like that of net and site.
