Astelle

Astelle is the het ship between Asta and Noelle Silva from the Black Clover fandom.

Canon
Noelle is Asta's squad mate in the Black Bull and fellow rookie. The two first met when Magna gave a tour to Asta of the Black Bull's hideout. When she first met him, Noelle was rude and patronizing towards Asta, due to her royal status, and thus paid him little mind. Furthermore, his loud and brash attitude irritated her. However, her opinion of Asta softened after he openly stated how amazing her magic is, which comes after years of torment and ridicule from her older siblings. Noelle quickly found herself on friendly terms with Asta which soon after turned into strong romantic feelings. The two spend most of their time together around the hideout and on missions.

Asta is very fond of Noelle as a friend but is mostly unaware of the romantic feelings she has for him. He supports her whenever she needs it, praises her abilities and has unwavering faith in her as a Magic Knight. His support has become a crucial pillar for Noelle as she often thinks of him when she wants to control her magic. While she can be rude and critical towards him, he remains oblivious and ultimately very kind towards her. At the Star Awards Festival, he admitted that he likes Noelle a lot after he sees her help a lost child, which caused Noelle to blush.
