Erica moves to Japan and also transfers to his school, causing him trouble on her first day. Godou meets Mariya Yuri, a shrine princess, and learns of The Committee for the Compilation of True History, a magic organization based in Japan. Erica brings Godou to Italy to meet the representatives of the country's Society of Magicians, and show them his new powers by facing him in a duel. The representatives decide to entrust Godou with an important artifact upon seeing his abilities.

瑪莉亞·尤里調查戈耳工石像鬼的到來，而神戶土和艾麗卡則尋找雅典娜。

Mariya Yuri is tasked by Amakasu to verify that a divine instrument called Gorgoneion has been brought to Japan by Godou. After she heavily scolds Godou, she explains to him the prophecy of Princess Alice about the Gorgoneion bringing about the world's end if obtained by the goddess Athena. Upon hearing this, Godou and Erica set out to find Athena, and either stop her or at least buy enough time for Mariya to seal the Gorgoneion. Unfortunately, Athena uses a surprising and unexpected move to take out Godou. Mariya on the other hand has been approached by a girl by the name of Liliana Kranjčar who at first wants the Gorgoneion, but then is willing to offer some aid in sealing the Gorgoneion.

雅典娜以獨立實體身份行動

難熬的日子

Godou 和 Erica 試圖在日出前從 Voban 的宅邸中救出 Yuri。

Amakasu asks Godou and Erica to rescue Yuri from Voban, since only a Campione can face against another Campione. As Godou and Erica make it past the obstacles in the mansion, Yuri voices her opinion to Liliana that Godou is not like the other Campiones. Once Godou and Erica meet Voban, Erica manipulates Voban into believing that Salvatore said that the elderly should accept their age and the youth should take over authority. In response, Voban releases Yuri from his mansion, for which he plans to hunt Godou down and take her back after giving them thirty minutes to run and hide. However, if they can last till sunrise, then he will admit defeat. After thirty minutes pass, a pack of wolves give chase, but Erica defeats them. Voban appears and summons an army of Dead Servants against her. Godou attacks Voban by calling forth the White Stallion, but Voban transforms into his werewolf form and consumes the White Stallion, prompting Godou to grab Yuri and retreat using the Raptor.

Erica enters into a fierce battle against Liliana. When Yuri tries to treat Godou for his wounds, Amakasu sends Yuri to persuade Liliana to stop fighting Erica and defect from Voban. Godou, Erica, Yuri and Liliana all prepare for the final showdown against Voban. Erica and Liliana deal with the Dead Servants surrounding them. After kissing Erica, Godou brings up Voban's past, annihilating the pack of wolves. However, in order to defeat Voban, Godou must successfully remake his golden sword, which will work after Yuri passionately kisses him. Even though Godou defeats Voban, the latter still has a trick up his sleeve, that is to completely control the weather. Godou uses the Goat to control thunder, and with the help of the three girls, he is able to defeat Voban once again. Although Voban survived the blast, sunrise occurs and Voban leaves while admitting defeat. (Source: Wikipedia)

Godou 在義大利度假時偶遇 Athena，而 Liliana 則在 Salvatore 破壞赫拉神廟後與 Perseus 展開對決。

In Italy, Godou is stuck vacationing on a beach with Erica, Yuri, Lucrezia and Arianna, but it is not like he wanted this to happen in the first place. Trying to escape their antics, Godou runs into Athena, who wants him to come with her towards something that has stirred up her feelings of excitement. Meanwhile, Liliana realizes the error of seeking Salvatore's help in dealing with the Heraneion, a grimoire shaped like a stone pillar located in an underground chamber. When Salvatore slices the Heraneion in half, it transforms the land's energy into a dragon above. A rogue god named Perseus shows up to valiantly slay the dragon without any concern for the consequences, ignoring Liliana's pleas. Fortunately, Athena intervenes, while Liliana takes Godou away from the area, explaining to him what Salvatore did. When Perseus pursues the two, Godou calls forth the Boar to attack, but Perseus survives. Using the Raptor, Godou charges at Perseus. However, Perseus shoots Godou with an arrow to the chest.

Godou 在面對 Perseus 的決鬥挑戰時與 Athena 進行談判

Athena stops Perseus from killing Godou, saying that Godou is much more interesting to fight after he has been beaten, which convinces Perseus to step back until next time. In another dream, Godou meets Pandora once again, where she notices that the Ram revived him, so she encourages him to defeat Perseus. When he recovers in Liliana's room, Liliana berates herself for her inaction earlier. Liliana's maid Karen Jankulovski tempts Liliana to prove her love interest in Godou, much to her embarrassment. Godou and Liliana then try to figure out how to counter Perseus's trump card. After Godou leaves to enjoy the view outside, Liliana later catches him reading her romance novel. Athena arrives to offer information about Perseus, but this means Godou will owe her a favor, to which Liliana rejects the offer. Liliana constantly struggles with her feelings with him when she tries to write love stories. She paralyzes him with tainted mint tea for her to personally confront Athena. However, Godou still has the strength to make the deal with Athena before she leaves. Meanwhile, Salvatore prevents the other girls from reaching Godou. Perseus soon after sends Godou and Liliana a message calling for a duel at a place he considers suitable for displaying his greatness to an audience. (Source: Wikipedia)

Godou 正面迎戰 Perseus，Liliana 則獻上致勝之吻。

Karen tells Liliana that the only way for Godou to defeat Perseus is through a kiss. However, Godou goes off on his own, disregarding such advice. When Liliana finds Godou near the coliseum, Perseus arrives and challenges him to a duel in front of the audience. Even when using the Bull to attack, Godou does not fare well against Perseus, much to Liliana's worry. Since Godou still does not have what he needs to achieve victory, Liliana makes a decision to kiss him, which gives him the necessary knowledge to defeat Perseus. During the battle, Godou reveals that Perseus disguised himself as a Greek god, for he is actually the Persian god Mithra. Although Godou breaks Perseus's bow and arrow, Perseus stabs Godou with his sword, but Godou uses the Camel to kick him away. Perseus then uses his ability to force Liliana into subservience to attack Godou, but Liliana manages to break free of the spell after hearing Godou call her name. Liliana shoots Perseus with her bow and arrows, allowing Godou to use the Boar to defeat Perseus. Athena appears to heal Godou's wounds by kissing him before departing, much to Liliana's chagrin. Perseus is killed by a shadowy figure with a scythe, who devours him in her serpent form. The other girls finally visit Godou in Liliana's room, where Karen had purposely told them about Godou's victory achieved by Liliana's kiss. (Source: Wikipedia)

Liliana 轉學至學校，Ena 向 Erica 發起挑戰，引發淨土之戰

Liliana also transfers to Godou's school, again much to Shizuka's chagrin. When Godou and Liliana go to Yuri's shrine, they meet Yuri's friend Ena Seishuin, who claims to be chosen as Godou's wife. Her intentions attempt to question how Liliana and Yuri each feel about Godou. This later gives Erica to finally have the opportunity to go out on her first date with Godou. Liliana and Yuri soon realize how they feel about Godou, while Erica reminisces with Godou on their first victory together against Athena. The date is interrupted by Ena, who challenges Erica to a fight to the finish. However, Godou tries to cease the fight, but he is instead sucked into a portal underground to the Purgatory, prompting Erica and Ena to jump in as well. Meanwhile, Athena literally drops in on Shizuka at the Kusanagi household looking for Godou. (Source: Wikipedia)

Godou在煉獄中與Susanoo對峙，而Erica則面臨Ena劍靈附身的死亡危機。

In the Purgatory, Godou meets Susanoo in a cabin, revealing himself as a god who is also Ena's guardian, and Godou begins to understand who Susanoo was before he retired to the Purgatory. Meanwhile, as they resume their intense fight in the mountains, Ena allows her sword to fully possess and control by her, which is gradually depleting Erica's energy. Liliana and Yuri witness a black aura filling the sky, covering the entire world. When Godou takes over the fight against Ena, she decides to retreat instead. As Erica is slowly dying, Godou tries to teleport her back on Earth, but ends up taking her to various places. At the Kusanagi household, Shizuka misunderstands the things Athena said about her relationship with Godou before suddenly leaving. On an island, as Erica says her last words, Godou finally masters summoning the Youth from Verethragna's spirit, having her ingest it through him to save her life and give her divine protection. While trying to rescue Godou and Erica, Liliana and Yuri are interrupted by the same scythe-wielding serpent goddess that consumed Perseus. At the shrine, when Ena reappears completely merged with her in the form of a god, Godou and Erica save her, but the serpent goddess, recognized as Metis, absorbs the power of Ena's sword.

Godou 回想起 Metis 的預言，並與女神戰鬥以拯救 Athena 和世界

Godou recalls from Susanoo that Metis, who is Athena's mother, wants to swallow the heavens as prophesied in the Gorgoneion, which actually does not pertain to Athena. Arianna and Amakasu come to retrieve Godou as well as Athena, who seems to have lost her memories after Metis previously absorbed her powers. Erica, Yuri, Liliana and Ena stay behind to try to buy enough time against Metis to allow Godou to recharge his powers. However, after the four are easily defeated, Metis comes after Godou, who manages to revive his powers. During the fight, Metis absorbs Athena's powers again, transforming her into her true goddess form. In order to prevent the prophecy from coming true, Godou receives help from each of the four girls to expose Metis's weaknesses. With the last kiss given by Athena after summoning her with the Gale, Godou is able to achieve victory, banishing the black aura from the sky and returning everything back to normal.
