After obtaining an artificial leg built for sport from Chidori the shady prosthetist, Kikuzato resolved to become a para-athlete. To strengthen his body so he can run again, Kikuzato wants to join the track-and-field club, but it's not so easy: His former soccer club friends have lost interest in him, his new clubmates don't know how to approach him, and his overprotective mother won't let him join any new clubs! With no easy ways to get faster, is the solution...to challenge everyone to a match?! (W/A) Wataru Midori
