Tagging note: when a post depicts Aine with large breasts, please also include the alternate breast size (larger) tag, as the size is not canonically accurate. See below for more info.
In the second season of the series (subtitled Kagayaki no Jewel), fans noticed an unexpected change in Aine's 3D model, which was altered to show a more developed bust. Interestingly, this change is not noticable in the 2D animated parts of the show (she still appears flat even in bikini), and no similar adjustments were made to the body types of other characters (see 3D model comparison here). When fans online discovered this, it quickly became a meme, with many fan artists exaggerating Aine's bust size in their illustrations. Aine was also humorously nicknamed ぱいね, a pun combining the words おっぱい (oppai, meaning "breasts") and あいね (Aine).
