Despite Eve's effort, Rufus defeats him with an ancient spell earning his team 10 points. The third battle is then decided to be fought by Fairy Tail's Laxus Dreyar, from Team Fairy Tail B, and Team Raven Tail's Alexei. However, chaos begins to rise when Raven Tail's elite members, consisting of Nullpudding, Flare Corona, Obra, and Kurohebi, all attack Laxus at the same time. Nonetheless, Laxus proves himself to be a tough opponent, taking down all of the members at the same time including his father, Ivan Dreyar. Lahar, Yajima, and Chapati Lola disqualify Team Raven Tail from the competition.
Afterwards, Wendy Marvell, from Team Fairy Tail A, is selected to fight Chelia Blendy, from Team Lamia Scale. While Chelia and Wendy enter the battle field, Doranbolt worries about Wendy whilst Lyon Vastia seems pretty confident in Chelia's strength. Chelia runs to the battle field and trips. Wendy runs down to the battlefield and asks her if she is okay but also falls down. The two greet one another and promise each other to have a good battle.
Wendy begins the battle with her Sky Dragon Slayer Magic's spell, Arms X Vernier to increase her offensive and speed abilities. Wendy then attacks Chelia with her Sky Dragon's Wing Attack. However, Chelia swiftly evades her attack. Around Chelia's hand, black wind begins to appear. Chelia sends a current of black wind towards Wendy's direction. Nonetheless, Wendy blocks the attack, but before she can do anything, Chelia comes face-to-face with her and hits her with her Sky God's Dance spell, sending Wendy flying into the air with another quick attack. Chelia tells Wendy that it's not over yet, and heads towards her, midair. Wendy attacks Chelia with her Sky Dragon's Claw. Both Chelia and Wendy fall back on the ground and both use their respective roars. Wendy using her Sky Dragon's Roar and Chelia using Sky God's Bellow. The two attacks clash, emitting a power shock wave through the entire stadium. Chelia comes out unharmed and reveals herself to be a God Slayer, whilst Wendy is trying to regain her balance.
Chelia reveals to Wendy that Lyon had once told her that a girl within Fairy Tail had a similar Magic to the one she uses. She then tries to apologize to Wendy, asking if she is okay. Wendy, while getting up, tells Chelia that it's okay, since they are currently fighting. Chelia then returns to her battle state and tells Wendy that they should enjoy themselves a bit more. However, Wendy contradicts Chelia, telling her that she does not find anything "enjoyable" about fighting, but that she will fight for the sake of her guild. Chelia, as she begins to cast another spell, also tells Wendy that she will also fight for her guild.
Chelia forces Wendy back with her Sky God's Dance attack. Wendy stands her ground, while thinking of her team-mates' efforts. Both Chelia and Wendy consume the wind around them in preparation for their upcoming attacks. Wendy takes the stance to perform a secret Dragon technique, shocking many of the viewers.
Chelia is surrounded by a wall of wind and is attacked by Wendy's Shattering Light: Sky Drill spell, which concerns the members of Chelia's team and surprises the members of Wendy's team, causing Chelia severe injuries. As Mato is about declare Wendy the winner, Chelia gets up with no visible injuries on her body. Chelia stands perfectly fine while Wendy wobbles on her feet trying her best to maintain consciousness. Chelia asks her if she is going to give up and also tells Wendy that she doesn't hate fighting but she believes that there's no love in a one sided-violence when the victor is clear. She also tells her that it's okay for her to give up. However, Wendy states that the reason why she still stands is so she can fight on behalf of her guild and tells Chelia that she does not need her pity. Wendy gets up and tells Chelia to fight her with all of her strength. Chelia takes Wendy's words into consideration. Black wind begins to surround Chelia's hands. The members of her guild tell Chelia, from the sidelines, to stop the attack, however, Chelia continues to cast the powerful spell.
Chelia's spell begins to take the form of wings, she sends her attack full speed towards Wendy. However, her spell misses Wendy, due to Wendy healing Chelia's physical strength. Wendy, not wasting any time, attacks Chelia with Sky Dragon's Crushing Fang, but Chelia heals her arm rapidly. The two slayers then begin to fight bare handed. Wendy attacks Chelia with all of her might while Chelia does the same, determined to win for their respective guilds. The time runs out and both Wendy and Chelia are out of strength.
Each team receives 5 points. Nonetheless, both Team Fairy Tail A and Team Lamia Scale are happy with the outcome of the battle. Chelia picks herself up and heads towards Wendy. She begins to use her Magic in order to heal Wendy's severe injuries. She then asks Wendy to become friends with her. At first, Wendy simply says yes, but Chelia tells her that she should reply like a friend would. Chelia extends her hand out, calling Wendy a friend, and Wendy happily accepts. The spectators are moved by the new friendship that has blossomed right before their eyes. With the final battle of the third day finished, the Grand Magic Games heads towards its fourth day.
