[Assistant] Irina, along with her team, observes the tournament from Issei’s room. Diehauser showcases his prowess by defeating God-class beings, eliciting Irina's admiration due to his participation starting mid-tournament. The emergence of new devils, Balberith and Verrine, alongside the Shooting Star team and their Sacred Gears, is noted. Rossweisse marries Chief-God Vidar. Asia and the team analyze Team Leisure of the Kings' members, focusing on Typhon's weather abilities, Apollon's potent light power, and Vidar's combat skills enhanced by mystical boots. Rias summons the team to a VIP area where Ajuka offers training via the smartphone game Beelzebut. During a training break, discussions about Issei lead Irina and Xenovia to contemplate the idea of becoming kidnapped princesses, inspiring Issei to save them. Irina finds the idea of being a kidnapped prince romantic and wants Issei to save her, however Xenovia informs her that it is impossible. Following training in Beelzebut, Irina, Xenovia, and Asia strengthen their friendship by sleeping together. On the day of the match, Irina accompanies her team to Valhalla for the fight against Team Leisure of the Kings at Thor Stadium. Irina joins Issei, Xenovia, Rossweisse, Ravel, and Ouryuu on the stairways of the artificial Yggdrasil. Xenovia, Irina, and Ouryuu become the first opponents to Apollon, the chief-god of Olympus. Irina introduces herself as Michael’s Ace and a member of Issei’s team. Irina and Xenovia attack Apollon, but he dodges their Ex-Durandal and Hauteclaire. Irina coats her Hauteclaire with her holy aura and attempts to slash Apollon, who counters with small amounts of divine aura. Despite their efforts, Apollon pushes Irina, Xenovia, and Ouryuu back. Irina declares Issei as her darling and expresses her belief in his victory. Upon hearing this, Apollon decides to fight seriously, disliking flashy fights. Irina and Ouryuu are defeated by Apollon, but their team wins the match due to Typhon’s loss. Irina and her teammates celebrate at the Hyoudou Residence with the rival teams for advancing to the main stage of the tournament. The Church Trio, including Irina, pull Issei away from his rivals, with Irina referring to him as her darling.

[User] What happens to Irina in True Volume 1?

[Assistant] Irina reappears after Rias announces her engagement to Issei and expresses interest in holding her own press conference, seeking approval from Heaven's higher-ups. Upon Issei's return from a devil job, Irina joins other girls in the bathroom to help wash his body, specifically washing his feet. She arrives at the park with the group to help deliver captured devils to the Underworld and discusses their appearance in various mythologies and Kuoh Town. Irina bickers with Xenovia about sleeping beside Issei, until Rias intervenes, allowing both to sleep beside him, resulting in all the girls sleeping in Issei's room. Irina goes to a town where the devils were residing and took some of them out with her light spears and took out her holy sword Hauteclaire to unleash her holy waves. Irina and the group are shocked to see Issei, Ddraig, and Bova in pain when the purple-haired girl was singing, but Rossweisse's hypnosis magic stops her.

[User] What is revealed about the purple-haired girl and what happens after that?

[Assistant] Ajuka reveals that the purple-haired girl is Ingvild Leviathan, a descendant of the original Leviathan and a half-human Longinus wielder. After Ingvild wakes up, the group takes her to a beach on an unpopulated island with Rossweisse placing a barrier. Irina and Xenovia go to swim in the sea and eat sandwiches made by Akeno, but are interrupted by the arrival of the goddess Nyx. Issei’s techniques fail against Nyx due to her Godly Virgin Killer Clothes. Irina and Xenovia equip their swords to fight in Issei’s place, with Xenovia expressing a desire to be embraced by Issei. After reporting to Ajuka about Nyx’s actions and gaining approval from Apollon, Irina watches as Xenovia attempts to help Issei lose his virginity to overcome Nyx’s Godly Virgin Killer Clothes. Heading to Nyx’s location, Irina and the group encounter devils; Irina, Xenovia, Kiba, and Lint remain behind to fight them while the others confront Nyx. Irina uses her halo rings and Hauteclaire to defeat the devils and protects Xenovia from an attack. Vasco and Cao Cao arrive to aid Irina and the sword group in defeating the remaining devils. After Nyx is defeated, Irina and her team go to the Agares territory for the tournament and learn they will be facing Rias and her team in the first match of the main stage.

Issei returns and saves the child held hostage by Jeanne and Heracles, defeating Jeanne. He encounters Cao Cao for the third time and is initially outmatched, despite Rias's efforts to recharge his power. Issei uses a bullet from Gogmagog, containing Samael's blood, on Medusa's eye being used by Cao Cao, reversing the situation. Cao Cao attempts to activate the Truth Idea, but fails because its effects rely on God's will in the Holy Spear. The True Longinus chooses Issei's wish instead of Cao Cao's ambition, leading to Cao Cao's defeat. Issei is officially promoted to a Middle-Class Devil, along with Akeno and Yuuto.
