High Guardian Spice[4] is an American animated television series created by Raye Rodriguez, who formerly worked for Danger & Eggs as a character designer.

[4][7][47] The show wrapped production in autumn 2019, as noted by Raye Rodriguez,[48][49] the series creator, and Anime News Network, even though Crunchyroll missed deadlines for release in 2019 and 2020.

[54] In May 2020, Alden Budill, head of global partnerships and content strategy at Crunchyroll described the series as "anime-inspired," like Onyx Equinox but said they are created by a "team of people who both love and respect anime as an art form because they are designed and produced by true fans who seek to infuse that same spirit into their content even though it is created outside of Japan.

"[55] On September 4, 2020, Ethan Supovitz of CBR described the series as an upcoming Crunchyroll original which would come out in 2020, but gave no exact date.

[6][68] Before the show's debut, Animation Magazine said that Rodriguez wants to make the world a "more loving and empathetic place by sharing fantastical stories about queer, diverse and relatable characters.

"[6] In a November 2021 interview, Rodriguez noted that he was inspired by Magic Knight Rayearth, Sailor Moon, Petite Princess Yucie, and Little Witch Academia, and described the show as having a "hybrid Eastern-Western cartoon style."

"[44] Rodriguez also said that the content warnings before episodes were not put there because of him, and that the series is not "an adult show" and that while there are curse words and mild blood, it is not for "mature audiences only".

Caraway- the sacred Alphabet's teacher- strikes up a conversation with the girls, before telling Rosemary he wanted to see her during her everything hours.

After leaving each other, Parsley gets the job of re-hanging a portrait, Sage tries to learn new magic, alongside Neppy Cat, and Rosemary meets Caraway in his library study and finds out that one of his closest friends is her mom- which, of course, she's shocked.

While that's going on, Amaryllis messes with Sage's potion, accidentally causing Neppy-Cat to become a full-grown cat monster, who starts running through the academy.

Due to the school being infested by little crab-like creatures called Trabers, Rosemary, Sage, Parsley, and Thyme have to head home.

Part 1: Olive and her cat begin looking at the rot on a tree, talking to "Smoke Face", saying that killing the girls isn't worth their time.

Olive schemes how to corner Thyme, Rosemary, Parsley, and Sage in the festival, believing she can turn them into stone and bring them to Witch Country, letting the Triumverate do the "dirty work".

All four girls go to different parts of the festival, with Thyme thinking back to her time in the Fairy Woods where she tried to help but was told to leave, her dad staying behind.

Thyme goes to her mom's house, packs some potions, and gets despondent when she sees a family photograph, writing a note saying she is going to the Fairy Woods.

Sage protects herself, Rosemary, and Thyme from Olive's spell, while Amaryllis and Snap are fine, but everyone else is turned to stone, including Parsley and Neppy Cat.

In March 2020, John Witiw of CBR said that the series reminded them of RWBY, Mysticons, and Harry Potter, while noting that the names of the characters are a reference to "Scarborough Fair", an English folk ballad made popular by Simon & Garfunkel.

[12] Another reviewer, Ethan Supovitz, also of CBR, said that the show has "a lot of anime influences", blending Eastern and Western animation, calling it reminiscent of Steven Universe, The Owl House, and Dungeons & Dragons, praising the creative team, variety of characters, while expressing worry about the show's style over substance, the number of "newcomers", familiar themes, and delay in release.

[11] Crunchyroll's announcement of the show prompted a negative backlash from some of the site's users due to the diversity of the cast and crew and inclusion of LGBTQ+ themes.

[77][1] Tom Capon of Gay Star News described Rodriguez as the "creative force" behind the show, noting that he'll be "leading an all-female writing room.

"[45] Jade King of The Gamer described the series as not being "afraid to showcase its queer identity" and called the characters "bright, colourful, loving.

"[80] Ritwik Mitra of Game Rant described the series as "pretty lighthearted and interesting," but criticized the pacing and premise, while arguing that "the LGBTQ+ representation in the show was a breath of fresh air.

"[83] On November 12, 2021, Crunchyroll announced that a pin set of characters Rosemary, Sage, Parsley, and Thyme, in the chibi style from the show's closing credits, could be bought from the company's web store.
