Futaba Break removes Light Screen and Reflect from the opponent's side of the field if it targets an opponent, then inflicts damage. Even if it targets an ally, it will not remove Light Screen or Reflect. It will remove Light Screen and Reflect even if the target is immune to Futaba Break (i.e. a Pokémon with Sap Sipper). It will not remove Light Screen or Reflect if Futaba Break misses or the target is protected from Futaba Break.
Futaba Break also suppresses the target's Ability.
Sharp clover leaves assault the target. It can also break barriers.
