lemon was the goalkeeper of team z (blue lokc) he was played as the goal keeper till selection 2 which is when you will start of with 3 players and when you win you can take one. But in the 3rd selection, unfortunately he lost. He was playing as a striker before Blue lock, but as of the anime, he is a goalkeeper. He's sweet, polite, and questioning. In the second selection he was playing with Kuon Wataru and Yudai Inamura, all of them lost and never appeared then.
