STORY
One day, you accidentally open the door to the Zodiac Realm. There you find twelve princes with dazzling personalities, as well as a butler.
Kneeling, the butler says, “Epilogia—the king’s oracle. We have long awaited your arrival. If you would, I beg you to lend us your strength and break us free from our doomed fate.”
The King of the Universe is gone, and his throne is empty. It is your destiny to choose and guide a prince to ascend and become King.
So spend your days engaging in conversation with the princes and forge deep, beautiful bonds. For you are the light that will illuminate their future.
CHARACTERS
ARIES ARILUS (CV: Daisuke Namikawa)
A quick mover! Pure of heart! That’s Prince Aries.
As pure as a spring lamb, he is a man of action who keeps moving forward, following where his curiosity leads. He’s an impulsive buyer and has been having money troubles since he came to Earth. He’s a bad liar and has an honest heart, so the other princes sometimes deceive him. He is cheerful and positive, but has a surprisingly soft side.
LEO LEPORON (CV: Tasuku Hatanaka)
Live big!
Lead boldly!
That’s the Prince of Leo way.
He’s big-hearted, loud, and full of energy! He’s a show-off who always wants to be in the center of attention. He likes gold and other shiny things, and his treasure trove is always sparkling. He claims to be the leader of the twelve princes of the zodiac, but they don’t seem to agree with him.
SAGITTARIUS SATALY (CV: Nobunaga Shimazaki)
The fun-loving, freedom-loving Sagittarius Prince.
He’s cheery and talkative and a born entertainer. He loves traveling and is always on the move, going from one place to another. He has the ability to make friends everywhere he goes. He’s an optimist, but he doesn’t plan ahead and does not think about things that don’t interest him. He also causes trouble by impulsively saying everything on his mind.
TAURUS UNUERA (CV: Soma Saito)
The prince of Taurus, a discerning and romantic gourmand.
Although he is laid-back and calm, he is also very curious. He likes to touch and even taste the people and things that look interesting to him. He is very particular and very stubborn.
VIRGO VILULU (CV: Yuki Sakakihara)
Neurotic and clear-headed, as well as a “good guy”, he’s the Prince of Virgo.
He loves to analyze and define things. He is too fastidious and that can irritate those around him. He is a perfectionist, but his attentive and anxious nature leads him to bottle things up. He appears confident, but is actually quite shy.
CAPRICORN CAPRIL (CV: Shinichiro Kamio)
The Prince of Capricorn: a serious, hard-working klutz.
He is very pragmatic and hardworking, always asking himself, “What can I accomplish here on Earth?” He is also an awkward person who has a hard time expressing his true feelings. In essence, he is a serious person who puts in a lot of effort, but sometimes makes careless mistakes. Secretly, he loves the cute things on Earth, but he hides that from the other princes, except Lalalivu.
GEMINI GEMIMINIA (CV: Takuya Eguchi)
The prince with two personalities, they’re the clever older brother and the rascal younger brother Gemini.
The wise and sophisticated older brother, Gemimi, and the mishievious younger brother, Miminia, share the same body. Although the prince sometimes seems to be talking to himself, it is actually just the conversation between the brothers.
Gemimi is logical and quick-witted, but can’t stand anything unreasonable. Miminia is curious but has trouble focusing on one thing. They both follow the shifting trends of Earth and of their own hearts.
LIBRA LALALIVU (CV: Koutaro Nishiyama)
Sociable and skilled, the Prince of Libra can handle anything with ease.
He’s a genius at reading the room and good at getting things done. He’s got charm and charisma that make him very popular. He wants to be seen as a good person who lives up to his high ideals, and he works hard to achieve this. But though he seems perfect at first glance, he is actually short-tempered, sarcastic, and irritable. He is lazy at heart and tends to push his work onto others.
AQUARIUS AQUNOA (CV: Shogo Sakata)
Lover of humanity and eccentric genius, the Prince of Aquarius.
He loves the science of Earth and is a self-proclaimed genius inventor. He loves clothes and fashion, but he’s messy, hates taking baths, and his clothes are always wrinkled. His personality is eccentric, but at first glance he is friendly and philanthropic. However, once he loses interest in someone he turns distant and cold. He only shows his true feelings in very rare circumstances.
CANCER CEREINU (CV: Fumiyoshi Shioya)
The prince of Cancer, the endlessly kind knight of sentimentality.
He is very nurturing and kind. Although he’s shy, once he gets to know someone he is very accommodating. He’s also very possessive and when he gets angry he stays at home and refuses to leave. He loves to be with the other princes, and longs to be with other people. He is surprisingly resolute when he makes up his mind about something.
SCORPIO DESCORE (CV: Nobuhiko Okamoto)
Mysterious. Passionate. The Prince of Scorpio, a dweller of darkness.
With a middle-schooler chuuni mindset, he believes himself to be the dweller of a dark world. He has a strong core and is totally devoted to the concept of love. He is jealous and vengeful and hold grudges easily. He has an extreme personality that always wants to make the world black and white.
PISCES PIXIZ (CV: Toshiki Masuda)
He’s mysterious, romantic, and sweet: the Prince of Pisces.
Possessing a delicate sensibility, he is able to read people’s feelings instantly. He values inspiration and treasures the unseen world more than anything. He is calm and gentle to the core, and somewhat out of touch with the world. Therefore, he tends to get distracted in the middle of conversations. He wants to live a relaxed life and laying about at home is the norm for him. He is very spoiled and good at getting what he wants.
HAJONOMIYA PLOVADIA (CV: Junichi Suwabe)
A butler of the heavens, appointed by the cosmos.
A steward dispatched from the Cosmic Royal Palace to act as the overseer for 12 individuals.
When the prince is on the verge of reverting to his newborn form, the butler appears out of nowhere to issue a warning,
primarily tasked with caring for him until he regains his adult form. Maintaining a delicate balance of distance,
the butler watches over the growth of the 12 from afar.
