Power Progression

Background and History

Ain trains under Zephyr and worries when he stays behind to hold off Weevil so his trainees can escape. When Roya reaches the survivors, she begs him to leave his phantoms behind and rescue Zephyr at full strength 38 39. After Zephyr announces his intention to retire, Ain chooses to continue training under Roya. She formally asks to accompany him, becoming his adjutant and student 48 49.

On Sabaody Archipelago, Ain confronts Doflamingo and refuses to retreat from his attack because civilians are behind her. Roya intercepts the attack, then orders her to report Doflamingo’s arrest to Sengoku 51 52. Later, on Fish-Man Island, Roya has her fight Vander Decken IX without warning her about his targeting ability. Ain identifies an opening herself, defeats him, and reaches the Great Swordsman realm 63 64.

Ain’s duel with Saka on Asuka Island brings another swordsmanship breakthrough. After Roya kills Saka, the Seven Star Sword attempts to tempt Ain with greater power; she resists it, and Roya destroys the blade 107 108 110. In a later battle against Kaido, Ain exploits an opening created by Perona to strike him and regress his age, sharply reducing his fighting strength 261.

Appearance

Ain is described as beautiful, with delicate features. She gives Roya a military salute when formally asking to train under him, but becomes visibly flushed when she admits she came to check on him after his fight with Saka 49 109.

Personality

Ain takes her duties seriously and follows Roya’s instructions, but she is willing to face stronger opponents to uphold her sense of justice. She stands against Doflamingo despite the danger to herself and the civilians behind her 49 51. She attributes her swordsmanship to sustained effort rather than natural talent and rejects the Seven Star Sword’s offer of a shortcut to power 108 110.

Her loyalty to Roya extends beyond their professional relationship. She resolves to become his “sharp sword” and grows embarrassed when she reveals how worried she was about him 104 109 110.
