Rikyu just gave Taki & Michiko a title. Meh. I'll explain the specialties a bit more in relation to how they use them in basketball. As you can see I base my characters around the specialties.
Rikyu has created his own playing style in basketball using his apparent invisibility. He acts weak and makes anyone marking him believe another member of the team will take the ball and not him. He manipulates the opposing team to focus on another player and then steps in without warning. When the opponent doesn't notice Rikyu, it is much easier to go for a steal. Misdirection is a play style that takes advantage of focus. This is how he was dubbed by Masura as "the shadow"
Rikyu uses his passes when attention is on the player with the ball. He must keep eye-contact with the receiver while preparing a pass, in order to get the ball and instantly pass it around to his fellow team mates.
Masura has the ability to copy movements due to his excellent perception. He normally has to see a movement once to completely copy it and make it his own. His ability goes further than this though: he imitates the movement, but plays it with more raw strength and speed than the first movement. When his opposing team plays a good style, he can often surpass them. His specialty of course has many restraints. Masura's ability is limited to technique, when one is very used to a movement and their body is used to it, Masura's body cannot suddenly adapt, so depending on the movement he will either be more or less powerful, never a perfect mimicry.
Michiko can watch teams Yamamura is playing against and review their strategies and patterns. She is capable of identifying and analyzing the specialties of any player and can then predict the movements and strategies their team will make. Michiko can then inform the Yamamura basketball team of the strategies and specialties, and then continue to develop countering strategies.
