The whimsical dreaming butterfly, Am Chouno!

—Am Chouno, whenever she introduces herself as one of the Rummy Labyrinth duo.

Am Chouno is a character in the second season of Cardfight!! Vanguard G, Cardfight!! Vanguard G: GIRS Crisis. Along with Luna Yumizuki, she is part of an idol unit known as Rummy Labyrinth. In order to save her parents, she joined the Company under the alias Ace, the person responsible for Shion Kiba's family losing their company. She was later fired from the Company after trying to save Luna from being a Peacemaker, leading her to join Plan G in order to redeem herself.


Am has short, blue hair, arranged to resemble a butterfly, as well as red eyes.

While working as an idol, she wears a butterfly headpiece, a butterfly choker, and a blue/black frilled dress, again with a butterfly motif.

She wore a blue jacket with a light blue undershirt, as well as dark blue jeans while preparing for the Dragon Empire G Quest.

In casual situations, she wears an orange jacket with a black undershirt which has a butterfly motif, and white skirt with long, black socks.

As Ace, she dons a short, pink wig, a Vanguard baseball cap, a yellow hoodie with a green turtleneck underneath, and black jeans.

In Cardfight! Vanguard G: NEXT, she grows her hair out, while still retaining the butterfly shape. Her idol outfit also changes to a short, white dress with blue and black segments.


Her family name, "蝶野" means "Butterfly field", while her given name is a play on the Japanese word amu 虻 meaning "gadfly."


Am takes her job as an idol very seriously, as a result she's rather distant from Luna, isn't used to hanging out with friends, and has a hard time opening up to others. Am also hates the winter, likely due to an accident that left her parents hospitalized.

Later into the series, she begins to open up to Luna, becoming closer to her. She also gets closer to Tokoha, being affected when she confronts her about her involvement in Ryuzu's plan. She also wanted her and Luna to continue their job as idols while keeping Luna uninvolved in Ryuzu's plans and unaware of her actions as Ace and later showed guilt and regret over Luna getting involved. Eventually she decided that sacrificing Luna is wrong and rebelled against Ryuzu's plans.

As Ace, she adopts an arrogant disposition, despising Shion due to his sheltered life in contrast to hers. Later she admitted enjoying her role as Ace and forcing Shion to see what life really is like.

She later appeared as Ace, along with Hiroki Moriyama. After Hiroki defeated Taiyou Asukawa in a cardfight she summoned "Chronocharge Unicorn", 1 of the Zodiac Time Beasts, to bring forth "Judgement" to the United Sanctuary branch, leaving her body exhausted afterwards.

In Episode 5, Am reveals the true nature of the Company to Luna, who goes to Tokoha for advice. While Luna is talking to Tokoha, Am interrupts them and tells them her reason for working with the Company: Her parents were rendered comatose in an accident, leaving her with the mitten as a keepsake. She wants to open the Stride Gate and bring them back, and for that she acts as the 'Peacemaker', one who summons and controls units from Cray. She also reveals that Rummy Labyrinth was chosen from children who had the potential to summon units. She then says that Luna is unnecessary and she can perform her job alone. Later, Am approaches Satoru Enishi about her unit summoning experiments, not wanting Luna to get involved. However, Luna states that she will "substitute for the mitten" and joins Am.

Am watches with Luna as Satoru Enishi fights Mamoru Anjou at the Dragon Empire Branch, and fights Ibuki after Satoru loses. Halfway through the fight, Luna takes Chronobeat Buffalo from Am and summons it, which promptly punches Ibuki into a statue of Dragonic Overlord and proceeds to destroy the Dragon Empire Branch, putting Mamoru into a comatose state in the process. Being visibly saddened by the devastation caused, Am leaves with Satoru and Luna.

Am is next shown watching over an unconscious Luna with Satoru Enishi, who reveals the cause of Luna's personality change. In a flashback, Am is shown taking part in an experiment with Luna, which causes severe pain due to the Stride Force required to control the units. However, an anomaly occurred during Luna's experiment, resulting in her losing her sense of self. Feeling guilty for her part in causing Luna's current state, Am breaks down in tears while apologizing.

In Episode 15, Am overhears a conversation between Shouma Shinonome and Satoru Enishi, learning that the Company's preparations are almost complete. Fearing for Luna's safety, she goes to free her but is stopped by Satoru Enishi, who she challenges to a Cardfight for Luna's freedom. Throughout the fight, Enishi continuously attacks her resolve, reminding her that Luna's sacrifice is necessary to save her parents and that Luna was only in a comatose state because of her desire to make Am's happiness come true. Am rejects a future brought about by sacrificing Luna, but is eventually defeated and expelled from the Company.

After being expelled of the Company and having nowhere to go, Am contacts Team TRY3 to ask for help to save Luna, revealing to them that Luna is going to be sacrificed to open the Stride Gate. She apologises and pleads with them for help, professing her willingness to accept punishment for her crimes. Unable to forgive her for her actions as Ace, Shion refuses and angrily walks off. Apologising again and thanking them for hearing her out, Am gives up and walks away, but is stopped by Tokoha who decides to help Am save Luna. Am promptly breaks down in tears while apologising as Tokoha embraces her.

The next day, Am approaches Shion on a rooftop, asking for his help in rescuing Luna. He refuses to forgive her, but accepts her offer to work together for Luna's sake. She then explains the mechanics of the Stride Gate to Team TRY3, Kamui, Taiyou, Jaime and Ibuki at Card Capital 2. Chrono receives a call from Ryuzu Myoujin, and they go out to meet him. Ryuzu makes them experience a flashback of his time with Rive Shindou, and opens the Stride Gate, which leaves everyone on Earth unconscious except Am, Team TRY3 and Taiyou. Chronofang Tiger explains to them that they are meant to be Arbiters, who will fight against the Company and Luna to determine whether Ryuzu's Perfect Future comes about.

In the next episode, Am, Team TRY3 and Taiyou enter the Stride Gate, where they are separated. Am lands on the floating wreckage of a ship, and sees Luna unconscious at the bottom. A projection of Luna appears, claiming to be Luna's will and they begin to fight.

Luna's will states that she refuses to allow anyone to prevent the perfect future from happening, for Am's sake, even if that person is Am herself. Am professes her willingness to wait for her parents to awaken naturally, as well as her desire to continue having fun alongside Luna, both on stage as idols and as friends. This causes Luna's will to momentarily revert to normal and ask Am to help her, so that they can continue to be together. Am wins, then flies over to Luna and embraces her while crying.

Two months after the Stride Gate incident, Am visits her comatose parents in the hospital along with Luna, who are slowly getting better with the help of medical technology provided by the Kiba Group. She laments her actions while in the Company, and resolves to make amends for her wrongdoings.
