byakugan!! 白眼!!
White eyes!!
(note: the word for the number "one hundred," hyaku 百, can be read as byaku びゃく if it undergoes rendaku 連濁, and then it's homonym with the "white" byaku 白. But don't be mistaken: the name of the eye is "white eyes," written with the kanji for "white," not "one hundred eyes.")
