On his way to the venue of the Hero Wars finals, Kaito and co. get a lift from a speed-loving man. As the tournament begins, Isshin, Hana, and Nagare clear their first matches. Kaito ends up pitted against the man he met earlier, former F1 racer Hayaiyen Messa, and his hero suit, The Grand Prix, whose speed proves to be a match even for Enter the Speed. Despite Enter the Speed causing a strain on his body, Kaito's determination to never give up allows him to overtake Hayainen and defeat him. Whilst returning home, Hayainen, who was burdened with a past accident that caused him to quit racing, decides to put it behind him and focus on improving his Hero Battle skills.
