Daisuke

He was a boy who was suffering from an illness and had to visit the hospital frequently. He is the manager of a baseball team. He met Nekomaru Nidai in the hospital when the baseball team were visiting him. Nekomaru asked why he became a manager when he can't join his team at the field due to his illness. Daisuke answered that even though he can't join his team on the field, he can at least support them and share their wins & loses. Daisuke later died before his team won the tournament. Nekomaru stated that is might have died as a result of working so hard in gathering stats for his team; but he also added that it could also be that Daisuke gathered stats so desperately because he knew that he didn't have that much time left before he past away. Nekomaru then took Daisuke's place as manager of the baseball team and help them win for Daisuke's sake. Daisuke ended up the reason why Nekomaru became a manager, and later the "Ultimate Team Manager".
