is one piece episode 845 filler?

After Big Mom's attack, Nami encourages Kingbaum to continue to live on for the sake of his fiancée, Lady Tree. The encouragement works and the homie runs faster than before.

Upon watching her manipulation, Pedro compares her to a devil while Carrot cheers her on. With Big Mom still on their tails, Luffy prepares to fight.

However, Nami stops him, claiming to have an plan. Nami licks her lips and uses her Sorcery Clima-Tact to release Black Balls, weather balls with thunder clouds within them, as Big Mom starts to attack again.

She claims that "Thunder likes thunder".
