The finish line of the Inter-High's second day is close. Imaizumi, Yuto, and Midousuji's race to the finish line heats up! Having removed his limited, Imaizumi rides ahead of the others. Meanwhile, Midousuji thinks back on visiting his mother in the hospital to more clearly imagine himself grasping victory. Finally, Yuto recalls a time when he simply enjoyed riding his bike with his older brother Hayato. "Have you heard the demon that appears on Hakone's straight roads has a younger brother?" Yuto becomes a sprinting demon like his brother! Who will win the battle just before the finish line?
I promised I'd show her 
the fireflies next year.
Ich hab ihr versprochen, nächstes Jahr
mit ihr die Glühwürmchen anzugucken.
Le prometí que le enseñaría
las luciérnagas el año siguiente.
Le prometí que le enseñaría
las luciérnagas el año siguiente.
On s’était promis

Le avevo promesso...
Eu prometi a ela que lhe mostraria
os vaga-lumes este ano...
Я обещал, что в следующем году
 покажу ей светлячков.
