After his family won three billion dollars in lottery, Natsuhiko Sakurada transferred to the Millionaire Private School, catered for the children from wealthy families, but far from just being rich, his decision to enter this school on his second year has a hidden purpose.
Years ago his childhood friend called Shin and him made a promise, they'll continue praticing and playing baseball until they reach the professionals league. Unfortunatly, just as he appeared Shin-chan vanished letting Natsuhiko behind with nothing more than a baseball ball carrying "Millionaire" inscription, the school name.
Therefor, this is all for the sake of seeking his childhood friend, Shin, whom he used to play baseball with. Unexpectedly his assigned room turns out to be Jinnai Masahiko's, who quickly tries to discourage Natsuhiko efforts of gathering a real baseball team.
Soon enough, Makino Hokuya let him now that Masahiko and his twin brother Toshihiko are masters of the Jinnai family, the second one being student and school chairman while Masahiko is the owner of the Titans baseball team, which Natsu-chan is the greatest fan.
Everything seems to be about luck and faith but who knows, Masahiko takes quickly advantage of his newly find uke (Natsu-chan) but he seems to have hidden secrets just as his twin brother has other plans in his hands.
