Wishun emerges as the sixth Heartiel discovered within the storyline, making an initial appearance in episode 20 of the series. This character embodies the virtue of "Wish," representing the narrative concepts of hopes and aspirations. Wishun communicates exclusively through riddles or rhymes, lending an enigmatic quality to all interactions. For example, the Heartiel issues cryptic warnings about "the truth" approaching, which perplex the protagonists despite their prophetic nature. A mirror serves as Wishun's symbolic representation, reflecting themes of perception and introspection. Following the initial appearance, Wishun joins the other collected Heartiels within the Queen Chairect off-screen between episodes 21 and 22, entering this repository of the Queen's will. No appearances or developments in other media such as movies, OVAs, or spin-offs are documented.
