Synopsis

Liko and Sprigatito are enjoying the breeze outside the Brave Olivine's observation room together. The camera quickly pans up to the sky and the series logo appears.

Friede enters the Captain's deck to check on Captain Pikachu and Charizard. A hardworking Orla wipes her forehead before exchanging a look with Elekid and Slugma. In the kitchen, Murdock's Alcremie fills a bowl with cream as Murdock and Rockruff are ready to make something out of it. Mollie is in the nursery with Chansey, Pawmi, Shuckle, Snorunt, and Alolan Muk, turning around in her chair as Chansey carries a tray to the opposite end of the room. Roy and Fuecoco skip and swing around together through a forest as various Pokémon they've encountered pass by in the opposite direction. Nidothing and Quaxly dance and get up into the fourth wall. Ludlow is fishing in the sunset as a Pelipper and three Wingull fly by him.

At night, Liko has her coat off and is on her Rotom Pad. She pets Sprigatito before looking out her window at the moon. A transition of her singing along with uncertainty panning to the left turns the screen blue. The next scene starts with Liko's feet walking to the rhythm of Sprigatito's wagging tail, and then Roy's hat swaying the rhythm of Fuecoco's head swaying. Liko holds her pendant before letting go, causing it to glow brightly as the camera zooms out. Liko and Roy lay down on the battlefield, exhausted as their partners come to their sides and they exchange a laugh. The camera zooms out, with Friede and his Pokémon watching the two, and a shooting star crosses over the ocean.

Liko commands Sprigatito to use Leafage, which Roy has Fuecoco counter with Ember. Orla, on her Metagross, and Murdock watch their battle. Mollie, Quaxly, and Ludlow are in the next scene. Noctowl, and then Friede with Charizard, and then Captain Pikachu are in the next. Roy holds one of the ancient adventurer's Poké Balls, gazing up at the clear sky surrounded by clouds where the Black Rayquaza flies overhead. Amethio battles Friede's Charizard with his Ceruledge, with fire in Friede's eyes. In the meeting room, Murdock places mugs around as the other Rising Volt Tacklers come in and are impressed. Liko and Sprigatito face away from the fourth wall, standing before clouds moving in the opposite direction she is facing. Liko becomes surprised when the other Rising Volt Tacklers walk by her and towards the Brave Olivine. They all turn around to Liko, with Roy waving for her to come along. Sprigatito jumps on Liko's shoulder and nuzzles her cheek, and she runs to join the Rising Volt Tacklers.

The final shot shows all the Rising Volt Tacklers walking together in front of the Brave Olivine. Liko, Roy, and their partners are in the center with Charizard and Captain Pikachu above them. Friede, Orla, Dot, Ludlow, and Quaxly are on the right with Metagross flying above them. Murdock, Mollie, Chansey, and Rockruff are on the left.

Trivia

• This is the first Japanese opening featuring humans to not feature Ash.
• This is the first Japanese opening not to be used in any dub, as the Asian dubs which had previously retained the Japanese opening replaced it with We Go (English Ver.).
• Among the first opening songs of all series, Heart-Pounding Diary has been used in the least amount of episodes before being replaced, at 23 episodes.

Errors

• In HZ002, the middle section of Mollie's jacket's left sleeve was incorrectly colored gray instead of red when she turns around to look at Liko. This was corrected in HZ003.
