Kumojaki is the leader of the Tree Cadets of Sabaku, and very loyal to their leader. Although being evil, Kumojaki believes in fair fights, and will never fight enemies that are too weak. As he mentions that the current Pretty Cure is the weakest in history, it is possible that he has met others than just them, Cure Moonlight and possibly Cure Flower.
Kumojaki creates of them as the weakest Pretty Cure as he catches the Blossom Tact off-screen. After watching his Desertrian being purified, he tells them his name and their strength status before giving Blossom her Flower Tact back and leaving.
Back at the castle, he reports to Kumojaki and a fierce battle ensues. Kumojaki has Cure Marine on the fence until Coffret throws himself at Kumojaki in an attempt to save Cure Marine.
Kumojaki claims that Coffret is only a fairy and has no real power and prepares to destroy Coffret. As he draws his sword back to make the final blow Cure Marine jump kicks his sword shattering the blade, much to Kumojaki's surprise making him state that she still has that much power and that the battle is about to get interesting.
Cure Marine tells Kumojaki that he is indeed strong, but he does not know what true power is and that Coffret is more powerful than him, due to his courage and bravery. She purifies Kumojaki with Blue Forte Wave, which causes Kumojaki to smile as he is lifted into the sky, by the purifying blue flower.
- Kumojaki is physically the strongest of the three cadets.
- Kumojaki is the only 1 of the apostles to be shown trying to get stronger, even developing new attacks to use against the Cure.
