Kidou Senshi Gundam: Suisei no Majo

Gundam Witch from Mercury HEAVILY draws from the premise of Shoujo Kakumei Utena, except adding mechs, a much higher budget, and removing all surrealism. There is no doubt that Kobayashi Hiroshi intentionally references Utena again and again. Both shows feature a high school girl repeatedly dueling for the betrothal right of a princess-type character who loves to tend gardens in her spare time. In this show, the personalities of the girls are somewhat flipped from Utena, with Mercury have a less confident personality and Rembran having a more confident personality, however the core dynamic between the characters is very similar. If you enjoy this Gundam show for more than just its action scenes, Utena is definitely worth your time. read more 

- Mecha shows that have a teenage cast - Politics x high school - A lot of strategies, both animes you see a business/organization form - Both have a queer character 

The series give the same vibes: - Overpower mecha "killing" their pilots. - Students founding their country/company. - Space theme. - Politics. 

Both unconventional gundam series. Instead of talking about great wars between nations or terrorist insurrections they focus on single duels and unique mobile suits 

New student, the wholesome facts, the group of protagonists give me the same vibe. 

It's a light-hearted yuri story about making friends with the new girl in class. 

Being at the top of the hierarchy comes with great responsibility and even more grief. An amazing watch for an accurate portrayal of the trenches of war that will touch your deepest sensibilities and show you the true meaning of friendship. 

Both series are more unique takes on Gundam and have more slice of life moments compared to other parts of the franchise. 

A show about a unique fighting school where an overly naive and ingenuous protagonist goes to study? Check. Representatives of different industrial and political clans study at the school, who turn the school for political ambitions and clarifications, whose version of a specific weapon is better? Check. A technology race with allusions to corporatism and the Cold War? Check. Is the MC paired with another character, with whom they has an imbalance in power dynamics and an unspecified platonic or romantic relationship? Check. In the future, the show turns into a political action thriller, where everyone forgot about the lessons? Of course. 

Both shows feature teenagers participating in duels involving the use of Gundam mobile suits. 

A futuristic combat school where students from different clans study, united by different versions of the same futuristic weapon? An arms race revolving around political ambitions and dynastic conflicts? An unwilling MC turns out to be the target of an forced engagement driven by their manipulative mother figure, who seeks vengeance against the world? Is everyone obsessed with trying to capture or defeat the MC because they are a potential doomsday weapon that could change the world, even though they are objectively nobody without it? The MC is an invincible OP with emotional issues while their partner is tsundere oujo-sama who is supposed to lead her family? The MC looks at her like she's an aristocratic boss when they actually care deeply about each other? Is the MC really the one for whom all this was conceived? Is the show obsessed with rebels and terrorists attacking a school as part of a more general world war theme? Does the theme of racism and class intolerance play a big role in the relationship between the characters? Are they really different shows? read more 

So, where to begin? Both shows follow a dressed in white similarly-named witch OP character (Suletta/Izetta) who uses nearly forgotten technology and skills to rescue a similarly-named princess (Fine/Miorine) who is her best friend from a political-military conflict. Both pairs of characters are similar in dynamics of a incredibly dedicated, but devoid of social experience red-haired simpleton x a strong-willed and possessing strong ideals, but at the same time emotionally immature princess. Although unlike Miorine, Fine is not such a tsundere. And in the end, both shows are pretty homoerotic, regularly walking the fine line between yuri bait-ish female friendships and ambiguous lady-knight relationships. In both shows, the head witch's abilities gradually become the focus of the plot and the focus of the war, despite the fact that initially the character simply wanted to protect a loved one. The overlaps between these shows only get stronger towards their finale, but I won't go into that in detail for fear of making it too spoiler, of course. In the end, we have two shows about a red-haired, socially awkward witch devotedly helping her best friend (lover?) princess win a political conflict, gradually becoming the center of the story herself because of the value of her abilities. It's possible that this was even intentional, as the writers of both shows are good friends who have contributed to different Gundam shows and even worked together on Geass. So, if you are interested in either of these two shows, then most likely you will like the second one. read more 

On the one hand, Oshi no Ko is a thriller about show business, and G-Witch is a space opera with mecha. But if you look closely.. Both shows are edgy revenge anime for Gen Z that revolve around important bonds of siblings, heavy personality-altering emotional trauma due to parental murder, and sociopathic protagonists who are torn between "life as a human child" and the brutally crafted goal of getting revenge on someone. Both shows even share the same OP artist, with both songs sounding like a cross between a high-energy J-POP and theme from a cool action game. Of course, these shows are not mirror images and they have noticeable differences in both protagonists and attitudes towards romance, but they still overlap quite a lot in their themes and work with the emotional development of their MCs. read more 

Both shows seem to be Ikuhara-inspired Mech shows in a school setting. Expect over-the-top insanity and subtle visual storytelling.
