Yumi Nagumo is a girl with a dream: Become the president of the United States of Amerigo! Unfortunately, she has no foresight and has no idea about Amerigo's culture. So, the second she lands in Amerigo, she needs help. In steps a group of vets in a Southwest diner who tell Yumi the best way to become president.
Join the Marine Corps.
Thus begins Yumi's adventures in the Marine Corps. Joining her are Linda Crawford, Donna King, and Rita Fernandez, as they enter boot camp and ready themselves for the Marine Corps.
Marine Corps Yumi is a manga drawn by Takeshi Nogami of Strike Witches and Girls und Panzer, and written and translated by Marine Anastasia Moreno. The series shows remarkable accuracy thanks to Moreno's former experiences.
Sadly, after a long battle with cancer, Moreno passed away on July 12th, 2015. The series was continued by Nogami as he was given the whole plot by Moreno before her death and the English translation was to be continued by Dan Kanemitsu. However, those English translations never appeared so Hyakuro Translations translated the rest of the chapters in April 2018. On June 20th, 2017, Takeshi announced that he had finished all the stories of Marine Corps Yumi for a total of seven volumes.
This series contains examples of:
- Alpha Bitch: Donna King shows shades of this, to the point where she enlists in the Marine Corps simply to prove herself away from her family name.
- And the Adventure Continues: The story ends with the main characters carrying on with their chosen careers.
- Artistic License History: Based on Yumi's birth year of 1984, the events of the story must have taken place around 2002 to 2004, while the story itself was written in the 2010s; some parts of the story are current at the time of writing rather than the supposed time frame, such as Yumi visualizing Barack Obama as the US President even though he entered office in 2009.
- Artistic License Military: Mostly averted in the series, thanks to the experiences of writer and translator Moreno.
- Happens during the Marine Corp graduation when the Eagle, Globe and Anchor is not depicted properly. This is justified as that symbol is a trademark of the USMC and the authors opt to not use the actual one in the comics.
- Moreno also points out any flaw in the depiction of the military in the summary below each page. Such as DIs not being as touchy as depicted and etc.
- Bluffing the Authorities: A recruit has had enough and tries to escape the island, but Yumi (who was on night watch duty) catches her outside the barracks. When confronted by the DI, Yumi covers for her by claiming she got lost on her way to the head. The DI lets it slide, but the next morning they're reminded that Barris Island is isolated, in case somebody "got lost" again.
- Chekhov's Classroom: Back in recruit training, DI Sergeant Garza explains how the Marines use the MAGOF concept (Marine Air Ground Operating Force). When Yumi becomes an interpreter and the JGSDF Chief of Staff is confused on the MAGOF concept that even his own interpreter doesn't know, Yumi delivers an explanation word-by-word identical to what Sgt. Garza taught her.
- Child of Two Worlds: Yumi is unknowingly a dual citizen of Nippon and Amerigo due to the latter's citizenship by birth policy. She had to give up her Nipponian citizenship in order to join the Marines, though.
- Classified Information: Stories about the Intelligence department are full of red redaction bars.
- Creator Cameo: Both Moreno and Nogami are present in the audience during the Marine graduation ceremony.
- Crouching Moron, Hidden Badass: Despite her ditziness, Yumi's high school buddies admitted that she has always achieved her goals. Her DIs and some fellow recruits thought she would be the first to wash out of boot camp, but they were proven wrong all the way.
- Distaff Counterpart: It could be compared to Terminal Lance, albeit in manga form and with a more consistent plot.
- Does This Remind You of Anything?:
- When Donna tries her hand at technical translation, the result reads more like a yaoi fan fiction.
- Yumi is a natural-born American citizen of color born in Hawaii who spent her childhood in an Asian country, like Barack Obama.
- Drill Sergeant Nasty: Subverted. The DIs show that they actually have a reason for their madness, from how the recruits sit to how they hold their canteens.
- Fictional Counterpart: Among others, we have the United States of Amerigo, Nippon, and the Barris Island boot camp.
- Five-Token Band: The four main characters are from different ethnicities, Yumi being Japanese, Linda being white, Rita being Hispanic, and Donna being black.
- Gag Boobs: Let's just say Yumi finds her motivation thanks to Linda's help during the PT test.
- Gas Mask Mooks: CBRN defense trainees are required to wear gas masks at all times, even when sleeping.
- Groin Attack: Linda doesn't appreciate free balls.
- Going Commando: A male PT decides to go without underwear under his silkies, which Linda doesn't appreciate.
- I Call It "Vera": Since the focus is on female Marines, this time the rifles are given boy's names.
- I'd Tell You, but Then I'd Have to Kill You: Rita's answer when the others asked about her work in Intelligence.
- Knockout Gas: Yumi has a very mild reaction to tear gas, which might be why she is assigned to CBRN defense.
- Mistaken for Servant: Or in this case, "Mistaken For Civilian". Yumi is brought along as an interpreter for an USMC delegation who are visiting their JGSDF counterparts after their regular interpreter is unavailable and choose Yumi as she speaks Japanese. But since she came with the delegation in a business suit, the JGSDF Chief of Staff assumed Yumi was a Civilian translator before meeting her again and realizing Yumi is a US Marine.
- Punny Name: The Japanese title Marinko Yumi can also mean "Marine Child Yumi".
- Raised Catholic: Linda and Rita go to church together on Sundays.
- Reused Character Design: Yumi's beloved school uniform design is reused in Girls und Panzer: Ribbon Warrior as the protagonists' school uniform.
- Running Gag: Yumi saying she wants to become a Marine so she can play with dolphins. It is later revealed that her mother is a dolphin researcher.
- Semper Fi: This manga is about the United States Marine Corps after all.
- Tall Tale: Yumi's birth on April 23, 1984. Her mother went into labor at Hawaii and apparently President fricken' Reagan and Nancy Reagan helped her give birth to Yumi, where Marine One helicopter transported her and her family to the hospital. Yumi (and whoever was there to listen) is not sure about this claim from her parents. But Reagan was on Hawaii on April 23, 1984...
- Title Drop: Done here upon Yumi getting her Globe and Anchor.
- Tears of Joy: Everyone has these upon finally completing the Crucible and becoming full-fledged Marines
- Up Through the Ranks: By the end of the story, Yumi and Donna have graduated from officer school and become Second Lieutenants, and Rita has become Sergeant Major like she has always wanted. Linda chooses to leave and get hitched instead.
