Noelle Silva

Noelle Silva is a noblewoman and the second daughter of the Clover Kingdom's House Silva, one of its royal families. She is also a 3rd Class Junior Magic Knight of the Black Bull and Royal Knights squads. Undine, the spirit of water, chooses to serve Noelle after her contract with Princess Lolopechka is temporarily weakened. Noelle uses this magic attribute to generate and manipulate water. She primarily uses this magic to shoot waterballs toward her opponents. Noelle uses the Heart Kingdom's magic technique and natural mana to generate and manipulate real water. Noelle uses this form of magic to shape objects and entities from water. Noelle uses this form of magic to increase her physical abilities. Noelle uses this form of magic to summon a spirit that can assist her in battle. She uses this magic to summon Undine, the water spirit. With this magic, she is a Saint Stage mage. As a royal, Noelle possesses an immense amount of magic power. It is large enough to create a giant sphere of water and waterspout and to shake the whole Seabed Temple. Channeling this power into her offensive spells, she can even challenge elves. She has difficulty controlling her magic power, which is shown from her attacks' lack of accuracy. She has begun learning better control and can restrain her power at will. Noelle is ranked as a First Stage mage.

After training in the Heart Kingdom, Noelle has learned to use the country's unique magic technique to increase the size and power of her Water Magic spells. Noelle wields a three-leaf clover grimoire that she uses to amplify her water-based magics. It has a cream-colored cover with intricate borders and a three-leaf clover insignia at the center of the front cover. Noelle wields a wand that she uses to help her control her magical power. This slender brown rod has a rounded tip and a round cut jewel set in the base. The wand's body also has a twisted design at the middle and gold ornaments at the top and the base of the handle. Noelle purchases a magical brooch from Dominante Code, and within it lives a magical lifeform, Bruce, who assists Noelle in improving her magic control. After Bruce dies, the brooch is reshaped and attached to the base of Noelle's wand. Noelle possesses a small device that allows her to communicate with the Magic Knights headquarters. It can send both audio and visual transmissions. Having been born into the royal family, Noelle can seem arrogant and vain. This can be seen when she denies Asta's act of friendship while proclaiming that she has not given him permission to talk to her. This also causes her to have difficulty admitting her failures, as she often tries to find excuses or blames her mistakes on somebody else. After finally coming out of her difficulties in admitting her mistakes, Noelle can also be seen as very reserved on expressing her delight over her achievements where she would rather suppress those feelings and shows her usual stern expression. She has a supposedly high sense of taste for items, as can be seen when she says that Magna Swing's broom is lame. However, due to having been rejected by her own family who had noticed her lack of control over her Magic Power, Noelle developed a slight inferiority complex to her more accomplished brothers and sister. This inferiority complex leads Noelle to try and prove them wrong to the point where she will overexert herself during training. Additionally, she is skeptical of the people around her since she expects them to react the same way that her family did. She is also rather modest, as she is mortified when she realizes her shirt is torn, showing her breasts slightly after the dungeon mission and is also slightly embarrassed wearing her bikini at the beach. Because of the Black Bulls' influence, notably Asta's, Noelle slowly begins to have more confidence in herself. This gives birth to a more courageous side where she is even willing to go against opponents like Vetto and her own brother, Solid. Kahono points out a reason that Noelle lacked magic control comes from her desire to not hurt anyone. This reveals that despite Noelle's shortcomings, she is a kind person which sets her apart from most nobles. Another aspect that sets her apart from other nobles is how she's less prejudiced towards commoners which was shown during the Star Awards Festival where she comforts a child and declares everyone should enjoy the celebration regardless of status. This confidence, courage, and kindness shapes Noelle a strong resolve to protect those she cares for, which creates a more selfless side to her personality. While her personality improves, her nobility and pride causes her to not always be honest with herself. The biggest example is her growing feelings towards Asta and how she tries to deny them.

Yuno Grinberryall

Yuno Grinberryall is an orphan who was left under the care of a church in Hage after the downfall of House Grinberryall, the former royal family of the Spade Kingdom. He wields a four-leaf clover grimoire and is a Magic Knight of the Clover Kingdom's Golden Dawn and Royal Knights squads. He is later promoted to vice-captain of the Golden Dawn. Sylph, the spirit of wind, chooses to serve Yuno after he finds her scroll in a dungeon. He is also the human vessel for the reincarnated spirit of Licht and Tetia's son. As the rightful heir to the throne of the Spade Kingdom, Yuno possesses a tremendous amount of magic power, as shown when not a single anti-bird flies around him during the Magic Knights entrance exam. His large reserves allow him to cast two different spells at the same time with ease. He easily fights on par with two of the Diamond Kingdom's Eight Shining Generals and defeats one of them. His magic power increases greatly while being possessed by an elf. He develops his skills and power and achieves the rank of Stage Zero. Yuno possesses the ability to sense mana from his surroundings. In addition, he can see the flow of mana in the form of a flock of winged beings.

Yuno can control all the mana in the area around him to increase his spells' power and range. He often uses this ability to generate spells behind his opponents, catching them by surprise. By combining Mana Zone with his refinement of Mana Skin, Yuno merges with Sylph and a vast amount of mana, increasing his magic power and transforms himself. The increase in power allows him to match that of Rill, a Magic Knights Captain but loses to Zenon Zogartis, a Dark Triad, using 55% of his devil's power. With further training and Sylph's help, the transformation is more complete, and Yuno is able to overpower Zenon at 80% but is pushed back at 100%. Due to being the host of the human-elf hybrid, Yuno possesses two mana affinities: Wind Magic and Star Magic. Yuno possesses a four-leaf clover grimoire that contains various wind-based spells, which he receives in the acceptance ceremony after he turns 15 years old. His grimoire has a gold-colored cover, the gold-colored four-leaf clover insignia at the center of the front cover and intricate ornaments around the borders. Yuno also possesses a spade grimoire that contains various star-based spells. He receives this grimoire after crashing into a grimoire tower in the Spade Kingdom. Yuno possesses a small device that allows him to communicate with the members of his squad. It can only transmit audio. Yuno has a calm and emotionless demeanor and speaks only when he really needs to convey his thoughts. His manner of speaking often makes people misinterpret what he means. Despite his detached nature, Yuno harbors a strong ambition to be the Magic Emperor, which he developed while growing up with Asta. Additionally, Yuno has a sense of rivalry with him so strong that he will go to any length to stop anyone who tries to put Asta in harm's way. He also goes out of his way to make Asta look good in the eyes of others, even to the point of Asta's expense, such as when he attacked Asta with his most powerful magic, knowing Asta would block it. Yuno is also known to be very blunt and not hold back what he thinks. Because he spent most of his childhood living with Asta, Yuno possesses similar traits as he does. One is his tenacity and will to never give up, both of which he learned from training together with Asta in their early days. Also like Asta, Yuno has proven himself to be both very stubborn and passionate when he it comes to his goals, and is not afraid to stand his ground against anyone who stands against him. Unlike Asta however, Yuno is not so quick to lose his calm composure in battle, which sometimes leads to him showing a more quiet, yet intense nature of himself. In contrast with his current personality, Yuno used to be more of a crybaby who could not stand up for himself. He started to change after Asta saved him while showing his dream and determination. Also in contrast with his personality, Yuno has been shown to be surprisingly protective of the people he views as allies, friends and comrades. This protectiveness however has been misinterpreted by some as arrogance. Yuno has also shown himself to be very considerate and conventional at times, like when he protected Charmy from danger, then afterwards accepted her snack out of both nourishment and kindness.
