At an age swiftly approaching thirty, Date is an old-timer for a boxer, but is nevertheless the man that Ippo looks up to. Years ago, he lost his World Title Match to the champion, Ricardo Martinez, who was defending his title for the 2nd time. He was knocked out in the 2nd round, and among other injuries, got a scar on the bridge of his then-fractured nose.

Date gave up boxing after that in order to settle down with his wife Aiko (a woman from a rich family who sacrificed a lot to be with him, and who just had a miscarriage at that time) and raise a family. But Date was a born boxer—he found he could not contain his combative nature for long, and after Aiko told him that she wanted their son Yuuji to see his dad fight, he picked his career back up to the top. Date is strong in every way, but his greatest weapon is the Heartbreak Shot, a corkscrew blow to the heart that immobilizes the opponent.
