Masaharu Nio

Niou is known as the Trickster of Rikkai dai, thus making him a very difficult opponent. Aside from being a skillful doubles player (alongside Yagyuu), Niou is also a strong singles player. He is the only player in Rikkai dai who has enough guts to go against Sanada's strict orders.He is able to completely copy the techniques and play style of other players, creating the illusion his opponent is facing another person. It isn't completely perfect, as there are moves that he cannot copy and he is limited by his own physical abilities. He often copies his doubles partner, Yagyuu, to confuse their opponents. He can predict the moves of his opponents up to ten steps ahead.
