Jushin Liger
This was one of the first anime television series to feature two opening and two ending themes, a tendency that has been followed since then by several anime television series. The "Ikari no Jushin", besides being still by Japanese wrestler Jushin Liger, has been used by the Hanshin Tigers as the climbing theme of pitcher Hirotaka Egusa. It's one of the anime themes that has been in constant use even after the TV show ended.
