Naval Battle is the 171st episode of the Fairy Tail anime.

As Fairy Tail happily parties in a bar to celebrate their earlier victories, others all around Crocus contemplate the harsh realities of things they have witnessed on the third day, and those to come. Malice also lurks in Sabertooth, as, in the Naval Battle event the following day, Minerva succeeds in brutally attacking Lucy as a demonstration of her guild's power.


Droy and Jet dodging barrel surfing

Natsu barrel surfs in the bar

Following their successful third day in the Grand Magic Games, the Fairy Tail Mages all gather at a bar in Crocus to celebrate. Congratulating Erza, Cana, Laxus and Wendy on their outstanding performances, the guild drinks and has fun, Natsu getting scolded for starting a barrel surfing game, which, despite it ruining the bar, everyone ends up joining in on.

Sergeant Yukino

"Sergeant" Yukino reports to Arcadios

However, as Fairy Tail celebrates, others around Crocus think about their own issues, Sting from Sabertooth confiding in Lector that he believes he will be fighting Natsu the following day, for which he is excited. In the shower, Kagura contemplates the meaning of Jellal being in Fairy Tail, whilst from the balcony outside, Millianna wonders the same thing. When Risley tries to get her to speak about her troubles, Millianna states that there is nothing wrong, though tells Risley that they must try their hardest to win the Grand Magic Games for their guild. The man on the two women's mind, Jellal, also thinks alone, walking through the streets as he remembers his identity being revealed earlier that day. All the while, in Mercurius, Yukino reports to her commander, addressing herself as "Sergeant".

The fourth day of the Grand Magic Games then gets into swing with the beginning of the event Naval Battle. Introducing Rabian as the guest commentator of the day, Chapati explains the rules of the event, where each competitor swims in a giant sphere of water and must try to knock the other players out without falling out themselves. When only two competitors remain, a five minute timer will be set, and, should one of the players fall out during this time, they will not receive second place, rather last.

Aquarius in Naval Battle

Lucy summons her trump card: Aquarius

When the game starts, each guild sends forth their competitors: Sherria, Jenny, Risley, Minerva, Juvia and Lucy make up the very much adored female portion of the players, whilst Rocker of Quatro Puppy is the only male, much to the crowds disliking. Once the event starts, Lucy hurriedly summons Aquarius right off the bat, hoping to take everyone out at once. However, Aquarius is countered by Juvia, who declares that she will not lose whilst in her own element, nor against her "love rival". As the two Fairy Tail Mages fight it out, Jenny uses the distraction to knock out Rocker, whilst the other woman begin to utilize their Magic to force each other out.

Seeing she is evenly matched, Aquarius decides to leave, almost costing Lucy her place in the game; the Celestial Spirit Mage just manages to summon Virgo and Aries to save her. Aries creates a wall of wool to absorb Juvia's Magic while Virgo keeps Lucy out of the way. Wanting to demonstrate her power, Juvia releases a new spell she learned after having her Second Origin activated, turning to cast "Wings of Love" at her opponents, the attack springing forth a cluster of heart-filled currents, as Juvia openly declares her love for Gray. The attack proves to be a success, knocking out Sherria, Jenny and Risley all at once. Happy with herself, Juvia turns to see Gray's reaction, however, upon seeing him appalled by the stunt she pulled, Juvia quickly becomes depressed. Before she can move to do anything else however, the Water Mage suddenly finds herself outside of the sphere, falling to the ground and receiving third place whilst her team berates her for losing focus.

Minerva defeats Lucy

Minerva and her "trophy"

It is quickly revealed that Minerva was responsible for Juvia's fall, her team stating that with her Magic, she could have pushed everyone from the arena in a matter of seconds. With just Minerva and Lucy remaining, the special timer goes into play, and Minerva is quick to attack Lucy through the water, forming multiple circles of heated water that explode and hit her, damaging and burning her. Lucy tries to retaliate by grabbing her keys, but discovers that Minerva has also managed to take them from her. Now defenseless, Lucy can do nothing but receive blow after blow from Minerva, who, despite being able to, does not push Lucy fully from the sphere.

Asking Lucy to give up, Minerva moves to cast another spell, though Lucy, close to tears, states that she will do whatever need be to win the game, as, if she were to lose, she could never look her team-mates in the eyes after all they have sacrificed and achieved. Hearing this, Minerva suddenly ceases her attacks until the five minute timer runs out, though, rather than just ending the match, Minerva screams that Lucy should not look down on Sabertooth, and begins to attack her even more ferociously than before. As the crowd watches on, shocked, Minerva attacks Lucy both physically and with her Magic, and, even when Lucy is about to fall from the arena, warps her back to the center to continue her brutal treatment. Seeing that the Sabertooth woman is just trying to rough Lucy up, many members of the crowd and commentators begin to try and stop the game. Quickly, Mato officially calls the round to a halt, stating that Lucy will be killed if Minerva continues. At this point, Lucy is barely conscious and beyond being unable to continue. As Gray, Natsu, and Erza glare at the smirking Sabertooth members, Minerva grabs Lucy by her neck and hoists her up and out of the sphere, dangling her like a trophy as the others rush to her aid.
