My Girlfriend Is the President

An alien spacecraft controlled by Ku Little Little launches into Earth, destroying the headquarters of the government of Nippon. To avoid chaos, the extraterrestrials brainwash the populace into the belief that Junichiro's childhood friend Yukino Ohama is leader of the country of Nippon. For some reason, the brainwashing does not affect Junichiro himself.[2]

The majority of the game's events and scenarios occur in the United States of Nippon, which is being controlled by Yukino, who was brainwashed to believe she is the president. The Snow House is ostensibly Yukino's home, however it is actually the camouflaged body of Starship Ezekiel. The Flare House is similar to the Snow House except it is sustained and kept by Irina Vladimirovna Putina, the president of Rusia. Lez Star is considered to be the largest and most powerful ship in the game, and it is the headquarters of Guardian and its members. Guardian is a fictional affiliation maintained by the extraterrestrials, the main antagonist, Joseph Soma Mirange, leads Guardian and opposes the protagonists along with Starship Jeremiah and occasionally Kuon.

Junichirō Hondō (本堂 純一郎, Hōndo Junichirō)

Junichiro Hondo is the story's protagonist. His actions tend to revolve around supporting Yukino, when not sexually harassing females. An incident earlier in his life resulted in his body's reconstruction, providing him with more power, having a memory that exceeds an ordinary person's, and an excessively tough body. For some reason, he remembers the original world before his childhood friend became president. His personality is that of a sociable, bright, and unabashed pervert with an honest heart. He likes girls and often gets beat up for his sexual harassment. Contrary to his usual playful attitude, he has a strong sense of justice and responsibility, acting with the belief of "I can do it!" and "This happens all the time in Hollywood." He is a parody of Junichiro Koizumi.[3]

Yukino Ohama (桜濱 雪乃, Ohama Yukino)

Voiced by: Aya Tachibana

Yukino Ohama, arguably the most iconic character, is Junichirō's neighbor and childhood friend who was selected to be president of Nippon after the accidental destruction of the previous administration. She has a brainwashing device embedded in her body, turning the world into one where the left becomes right if she says it is. Her approval ratings climb rapidly due to her looks, personality and the brainwashing effects. She even has a fan club among the government officials. She is also known to love anime and manga making her supporters to call her ‘Your Excellency’. She is a daughter of doctors, good at sports, and has excellent grades. Even with that, she isn't boastful about it, and has a modest and gentle personality. Although she wears the mask of a prim and proper high-class lady, but is clumsy and spoiled in her private life. She is also an extremely shy person, fretting over messing up her lines and blushing during speeches. Since she set forth the "Jun-kun Supremacy Doctrine" and has a troublesome side of passing crazy laws for the sake of love, disputes between Junichiro and the bureaucrats never die out. Junichiro embarrasses her often with perverted comments, that causes her to blush more than mildly. Sometimes she pretends to be a dog and plays around with Junichiro which leads to Irina lecturing them. She is a parody of Barack Obama.[3]

Irina Vladimirovna Putina (イリーナ・ウラジーミロヴナ・プチナ, Irīna Urajīmirovuna Puchina)

Voiced by: Erena Kaibara

Irina Vladimirovna Putina is an active duty president who reigns over "Rusia" (Russia) with super charisma. She obtains information that a UFO crashed into Nippon, and visits to talk about laws dealing with import restrictions. On the day of her visit, Irina is seen assaulting a strange man and when she strikes back, Junichiro rescues her, which causes her to become dumbstruck. As it turns out, the man placed a bomb in the building because he suspected something similar to this may happen, so Junichiro escapes with Irina heroically and afterwards she exposes her gratitude. She later visits the Snow House as a guest of Yukino and is able to recognize James Hondo (Junichiro gave her a fake name when they first met), she hugs him to everyone's shock and tells him to become her husband. Yukino makes matters worse by stating that Jin is to be her First Gentleman; a huge scandal erupts as the two women argue over Jin. She becomes interested in him ever since, making an appearance at his school as a transfer student while handling government affairs. However, she becomes disillusioned by the protagonist, the great king of sexual harassment. She disciplines him with her slapping fan to make him into a gentleman even to this day. As a disciplinarian in school, correcting the behavior of the students is her daily routine. She fosters a rivalry against the childhood friend president who's also the head of the student council, and seems to have plans to correct the entire school as a disciplinarian. Yukino and her friends nicknamed her Puchin, but she gets mad when they call her that. She is a parody of Vladimir Putin.[3]

Due to having limited knowledge pertaining to sex, she obediently receives Junichiro's sexual harassment. Ell is the younger sister of Starship Jeremiah, better known as Remi, the two share a rivalry because Remi is jealous that her creator Ku Little Little seems more prideful of her newer creation Ell than herself.
