Black Clover is a fantasy anime and manga series created by Yuki Tabata, featuring intense world-building, magic conflicts, and unforgettable characters.
The plot primarily concerns two orphans, Asta and Yuno, who aspire to become the Wizard King, although their talents differ. Although it is typical to focus on these two heroes and their allies in the Clover Kingdom, the series also throws the limelight on different Magic Knights captains, who each have their own personalities and back stories. They include Rill Boismortier, the young and quirky leader of the Aqua Deer team, whose innovative application of Painting Magic makes him a favorite. Black Clover often prompts fans to speculate about the personal lives of these characters, particularly regarding romance.
The most common question is whether Rill Boismortier is in love with someone in the story.
The blunt fact is that Rill Boismortier has no established love interest in Black Clover. Although some scenes in the manga and anime may have hinted at his interest in relationships, he is not on record as having been romantically involved with anyone. Rill is mainly depicted as an eccentric and light-hearted captain and is more concerned with art and expression with magic than with the heart. The plot has not established any romantic subplots, unlike some characters, such as Yami Sukehiro, who occasionally shows signs of attraction to Charlotte Roselei, or Charmy Pappitson, who is more open about liking Yuno. In his part in Black Clover, he has been more thematic, reflecting the youthful imagination, artistic vision, and new outlook he offers in the Magic Knights ranks.

The character of Rill gives more background on why romance has not been a focal point of his character. He is also among the youngest captains in Black Clover, and his carefree attitude makes him appear more interested in play and art than in leadership and romantic relationships. Rill sees magic and battle from the perspective of an art, frequently lost in his own inner fantasies instead of planning in a usual way.
This imaginative alienation also implies that he lacks the sort of storyline that could readily bind him to a romantic plot. Instead, his motive in most instances serves comic relief or as a shock to the battlefield.
With that said, some fans have speculated about potential future relationships that Rill could have. A speculation is that of Charmy, particularly following their interactions in the Elf Reincarnation Arc. When an elf spirit took over Rill, his clash with Charmy contributed a comic element to the otherwise anarchic moment. Yet, these exchanges were mainly comedic in nature and not a romantic progression. Others posit that his playful attraction to beauty and art might result in a romantic interest later in the series, but, as of this time, the story has not substantiated this.

Lack of a love interest for Rill is also indicative of what Black Clover is all about. Black Clover has also remained mostly battle, rivalry-focused, and perseverance-oriented, unlike other shonen series, where romance is a major subplot. Romance is seldom the focus, unless in brief moments, so characters like Rill are less likely to be given an arc about relationships. His story is more about his development as a leader, his devotion to his squad, and his artistic perception of the world.
Rill Boismortier and Relationships in Black Clover
Upon closer examination of Rill and his role in Black Clover, one will notice that his relationships are defined more by friendship and artistic interest than by love. His Aqua Deer team admires his creativity, although they may not always like his leadership approach. Rill treats his squadmates more as peers and does not show as strict authority as other captains. This effort highlights his youthful essence, but also confirms why he has not been cast in a romantic part. Romance would require a shift in emotional maturity, which the character has yet to demonstrate.
One more aspect that needs to be mentioned is that the art-oriented personality of Rill might be regarded as his love in Black Clover. He shows love, happiness, and amazement by Painting Magic and tends to lose himself in the beauty of creation. This metaphorical relationship with art serves as a substitute for romantic involvement.
To Rill, painting is not only a magic power but a way of living, and this might be why the series has not focused on romance. His art is his love, his identity, and it is more important than a typical love story.

Nevertheless, one cannot rule out the possibility that Black Clover can still develop its characters in subsequent arcs, and the young Rill will have some opportunities in the future.
Rill might later be provided with a love interest as Yuki Tabata explores more personal relationships when it comes to the captains. Until that point, viewers are led to believe that his plot has been constructed without a romantic center, which supports his role as an icon of creativity and innocence in the otherwise battle-toughened world of the Clover Kingdom.
Finally, Rill Boismortier does not have any love interest in Black Clover. The influence of his position is evident in his artistic imagination, his carefree style of leadership, and his contributions on the battlefields.
Although the fans may only guess what will happen next, Rill is currently a character who is more about art and creativity than romance. Black Clover still employs him as a rejuvenating contrast to the more serious captains, so that his presence is a unique feature that does not require a confirmed love interest.
