Rhya distances himself and puts out the fire while healing himself. Asta decides to jump into the fight, but Mereoleona replies that he would get killed if he jumps in. Rhya wonders how she will fare against the spells he has collected from his comrades. He launches several blades of light, which Mereoleona counters with a flurry of punches. Rhya thinks about how Mereoleona's movements are not even human, while Mereoleona quickly gets behind Rhya. As Mereoleona attacks, Rhya uses Invisible Scout to evade the attack. Rhya counters with Aqua Javelin, but Mereoleona easily counters and distances herself from Rhya.

Zora thinks about how Mereoleona is on a completely different level, and that Mereoleona lived in the forest after she felt too stuffed up in the capital. Zora also thinks about how its true from the rumor of Mereoleona reach a stage even higher then Mana Skin. Zora then thinks about Rhya's Imitation Magic, having reasoned out that Rhya can use any magic but only one at a time. Asta marvels at Mereoleona and wonders if there is anything that he can learn from this match. Rhya says that Mereoleona is a pain, and pulls out the Demon-Slayer Sword while wondering if she can deal with it. After witnessing this, Zora figures out the condition that Rhya needs to do in order to imitate a person's magic. Rhya remembers when Licht commented about how Imitation Magic suits him since Rhya is a kind person. Rhya thinks about how Licht was wrong and how he killed the people who tricked and killed Licht. Rhya then thinks about how he will kill every last human. Mereoleona easily breaks the sword, and comments about how Rhya could not copy Asta's Anti Magic.
