Hanazuki: Full of Treasures

Moonflowers are the guardians of the galaxy's moons. Created by Little Dreamer, they have white flowers on their heads and highlights that change color depending on their moods, enabling them to grow Treasure Trees that protect their moons from the Big Bad.

• Hanazuki (voiced by Jessica DiCicco) is the titular protagonist of the series. A newly born Moonflower, Hanazuki is a kind, friendly, and optimistic girl who always offers help to those who need it. She is quick to adapt to her role as her moon's guardian, allowing her to understand and control her own emotions more successfully than most other Moonflowers.
• Kiazuki (voiced by Cassandra Lee Morris) is an older, cynical Moonflower who lives on a moon ravaged by the Big Bad. Although claiming to be more experienced than Hanazuki, Kiazuki has failed to ever grow a colored Treasure Tree of her own, and envies Hanazuki's success. She thus manipulates Hanazuki, who admires her as her "Moonflower sister", into helping her acquire treasures to restore her moon. She is later revealed to be the founder of the Garlandians, a failed emergency response team devised to combat the Big Bad.
• Kiyoshi (voiced by Vargus Mason) is a male Moonflower who protects a moon inhabited by unicorns. Because of his pessimistic nature, he is only able to grow black Treasure Trees, which are ineffective in warding off the Big Bad. Deposed and exiled for his failures, Kiyoshi receives guidance from Hanazuki to properly harness his emotional powers, eventually regaining authority of his moon.
• Maroshi (voiced by Marcus Toji) is a Moonflower from an ocean-covered world that is frozen and shattered by the Big Bad. Despite losing his home, he maintains a positive, laid-back attitude at all times, which makes him easy for others to get along with, but also appearing somewhat irresponsible. He is talented at flying through space on a surfboard-like device.
• Miyumi (voiced by Elise Dubois) is an outgoing & confident Moonflower who is always sure about herself despite not being mean. She can be irresponsible & self-centered since she prefers to enjoy herself. But in the end she realized that she can be totally responsible since she learned her lesson.

The Hemka (or Hemkas) are small, rabbit-like creatures that inhabit Hanazuki's moon. They speak in gibberish that others except Hanazuki can fully understand, and they have malleable bodies that allow them to merge and change into different objects. Each Hemka is of a different color and represents a specific personality trait that Hanazuki reflects.

• Red Hemka (voiced by Colleen Villard) is a feisty Hemka prone to picking fights and pulling pranks on others. Red often acts as the leader of the other Hemkas.
• Orange Hemka (voiced by Michael Sinterniklaas) is a wacky Hemka who often jumps around and makes silly faces.
• Yellow Hemka (voiced by Colleen Villard) is a happy Hemka who enjoys playing and remains optimistic in dangerous situations.
• Lime Green Hemka (voiced by Jessica DiCicco) is a scared Hemka who is easily startled by anything.
• Green Hemka (voiced by Michael Sinterniklaas) is a mellow Hemka who speaks with a laid-back tone.
• Teal Hemka (voiced by Michael Sinterniklaas in season 1, Cassandra Lee Morris in the shorts) is a glamorous Hemka.
• Blue Hemka (voiced by Jessica DiCicco) is a sad Hemka who is constantly crying or on the verge of tears.
• Lavender Hemka (voiced by Michael Sinterniklaas) is an inspired Hemka who has creative ideas but is too shy to act on them.
• Purple Hemka (voiced by Michael Sinterniklaas) is a courageous Hemka who performs feats of derring-do.

• Emerald Hemka (voiced by Avery Waddell) is a Hemka that represents Jealousy

Unicorns in the series are native to Kiyoshi's moon. They possess the same colors and personality traits as the Hemka, with the additional ability to perform magic using their horns. Most unicorns in the series are voiced by Debi Derryberry.

• Sleepy Unicorn (voiced by Avery Waddell) is a unicorn who lives on Hanazuki's moon and, as his name suggests, spends most of his time sleeping. Despite his relaxed and lazy nature, he harbors a troubled past; originally named Noble Unicorn, he lives in exile from his home moon after failing to stop his brother Twisted Unicorn's revolt against Kiyoshi. Convinced that he is unfit to wield magic because of his failure, Sleepy regains his confidence to use his powers again to help Hanazuki.
• Twisted Unicorn (voiced by Avery Waddell) is Sleepy Unicorn's brother and the leader of the unicorns. Twisted is a tyrant responsible for overthrowing Kiyoshi, forcing his fellow unicorns to maintain a force field he professes will protect their moon from the Big Bad. He is eventually deposed by the combined efforts of Hanazuki, Kiyoshi, and their allies, leading Twisted to hunt them across the galaxy for revenge.

Sloth-like creatures that live on Miyumi's moon. The others were voiced by Cassandra Lee Morris.

• BB (Elise Dubois) is Miyumi's favorite teal Slooth who likes everything fabulous just like her.

• Little Dreamer (voiced by Colleen Villard) is Hanazuki's infant-like creator who delivers treasures to the Moonflowers. He is shown sleeping at all times and wearing different-patterned pajamas almost every time he appears.
• Dazzlessence Jones (voiced by Avery Waddell) is the self-appointed sheriff of Hanazuki's moon who resembles a diamond. He helps Hanazuki maintain order, and speaks verbose words through song.
• Zikoro (voiced by Avery Waddell) is Kiazuki's sole companion on her moon, a black creature who behaves like a restless dog. He is regularly mistreated by Kiazuki, but remains loyal to her and enjoys tormenting the Hemka. After Kiazuki abandons him on Hanazuki's moon, he takes more of a liking to Hanazuki and her friends.
• Chicken Plant (voiced by Alison Martin) is a grouchy plant with the resemblance of a chicken that constantly tries eating the Hemka. She is prone to laying eggs that hatch into destructive monsters.
• Mirror Plant (Shondalia White) is a plant that translates an individual's thoughts and repeats what the subject says.

Hanazuki: Full of Treasures was met with critical praise and online popularity upon release, with several favorably comparing it to the television series My Little Pony: Friendship Is Magic (another Hasbro property) and Steven Universe for its light-hearted tone, visual aesthetic, and methodical storytelling.[3][4][5] As of May 2017, the series has accumulated over 120 million views on YouTube.[6]

In her review of the series, Lauren Orsini of Forbes commented on the involvement of Friendship Is Magic writer Dave Polsky as a story editor, considering Friendship Is Magic to be lucrative to Hasbro's success, and concluding that the series was an attempt by the company to incite similar success with Hanazuki.[3] In a later article, Orsini attributed the series' popularity on YouTube to its "spunky characters and high production values".[21] Mercedes Milligan of Animation Magazine said of the series, "Hanazuki puts a modern, cross-platform spin on a premise that will be familiar to '80s kids who grew up with Rainbow Brite, et al."[9] Ella Anders of BSC Kids praised the opening episodes for its setting, lore, characters, and overarching storytelling. She additionally interpreted the series as a Western magical girl series that "doesn't play off the traditional magical girl path or tropes".[4] Nathalie Medina of iDigitalTimes gave the series a score of 4 out of 5, complimenting the characters and hints of a more complex underlying story, and comparing its visual style to "a Lisa Frank folder with a 2000s aesthetic".[5]

The web series was made in conjunction with a line of Hanazuki toys first announced at the 2017 New York Toy Fair, which was launched in June that same year.[6][2] A digital app for the series was released for iOS and Android on April 4, 2017, offering a tie-in interactive video game along with episodes of the web series.[6][23] A companion book authored by Brandon T. Snider, titled Hanazuki: Book of Treasures – The Official Guide, was released on November 7, 2017.[24] A series of four chapter books set within the universe of the web-series was also announced, with the first book written by Stacy Davidowitz, titled Hanazuki: A Spark in the Dark, released on May 8, 2018.[25]

A Hanazuki short was released theatrically with Hasbro Studios' My Little Pony: The Movie on October 6, 2017,[26] the plot of which focuses on Hanazuki as she tries to get a treasure back from the playful Yellow Hemka.
