Ikusa-Tsunagi is the 283rd episode of the Fairy Tail anime, and the 6th episode of the 2018 series. It aired on November 11, 2018.

Arlock summons one of the Yakuma 18 War Gods known as Ikusa-Tsunagi to slaughter his own men in order to draw out Zeref, revealing that this was the true purification plan all along. Natsu is enraged and faces Ikusa-Tsunagi in a one-on-one battle, eventually coming out victorious while later learning of the averted future that Rogue went on to rule.


Arlock is defeated

Natsu defeats Arlock

One of Arlock's followers tells him that every one of the Avatar branches is about to be wiped out. Natsu tells him to just give up because he's never going to win. Arlock raises his staff and fires at Natsu. Natsu deflects it and runs towards Arlock. Arlock continues to send magical attack at him but Natsu deflects. Arlock raises glass barriers that Natsu can't get through but Arlock's attacks can. Natsu says that isn't fair and tries to break through Arlock's magic walls. The other followers believe that Natsu won't be able to get free but Natsu proves them wrong and bursts through the wall. Arlock summons more but Natsu gets through every one of them. Natsu jumps and brings his fist down on top of Arlock sending him falling to the ground.

Natsu tells him to give up but Arlock tells him that he's lost. Natsu is confused but Arlock goes on to say that he burned off his face for this. He raises his arms and calls upon Ikusa-Tsunagi. The sky suddenly darkens and both Happy and Lucy wonder why that is. The ground starts to break apart and the followers worry that the magical storm is going to get them as well. Suddenly, a gigantic foot comes from the sky and lands on top of many Avatar followers. Natsu orders Arlock to stop it because he's killing his own people. Arlock says that that's the true plan. That the souls of the Avatar devotees are the true sacrifice. Arlock tells him that Ikusa-Tsunagi won't stop until everyone is dead. Erza can't believe that they summoned one of the Yakuma Eighteen War Gods Magic.

Natsu vs. the Yakuma Eighteen War God

Natsu can't believe that Arlock doesn't care about his own men. He decides to end this battle now. Suddenly, Ikusa-Tsunagi slams his sword onto the ground and the earth separates. Natsu uses this chance to climb onto the sword and runs the length of the blade towards Ikusa-Tsunagi. Arlock tells him that there is nothing he can do because he is a god of battle. He tells his comrades to sacrifice their souls to Zeref. Natsu can't believe that Arlock doesn't care about his friends. Arlock tells him that friends are a means to an end. Natsu explains to him what friendship really is about but Arlock claims that that's only dependency. Natsu tells him not to underestimate the power of friendship as he finally reaches the god's face. He jumps and his fist ignites with fire before he slams it down onto Ikusa-Tsunagi's head. Nothing happens but Natsu vows to get stronger. He tries again and this time the god suddenly begins to crack and explodes into pieces.

Arlock claims that what Natsu just did is impossible. Natsu lands on the ground and the followers of Avatar run away claiming that he's a monster. Abel and D-6 say that they will proceed with the Purification Plan themselves when Gajeel and Panther Lily arrive. Gajeel tells his army to arrest everyone and to not let any of the Avatar followers escape. Gajeel, Panther Lily, and Levy reunite with the others. Natsu can't believe that Gajeel works for the Magic Council now. Gajeel tells them that Warrod offered him a job because he needed to eat. Gajeel tells them all, especially, Gray, that they're going to be arrested. Erza hits Gajeel in the head from behind. They still don't believe Gajeel is Gajeel because he'd never work for the council. Panther Lily confirms that it is Gajeel.

Victory shout

The Mages celebrate their triumph

Erza explains that they stopped Avatar's Purification Plan but that the real credit goes to Gray. Panther Lily concedes that they'd never have found them without Gray's help. Everyone gathers together and is happy to have been reunited once again. Happy tells Carla that it feels like they're in their guildhall. Rogue and Sting arrive at the battlefield too late to help but marvel at what Fairy Tail has done. They suddenly realize that Frosch is missing but find him mingling with Happy, Panther Lily, and Carla. Natsu gets upset when he sees him because that means Rogue broke his promise about staying and not leaving the city. Natsu watches Gray interact with Frosch afraid that he's going to kill him. When in reality, Gray hugs Frosch and comments about how cute he is totally throwing Natsu off.

Sting and Rogue come running up to congratulate them. Rogue demands that Gray give Frosch back. Natsu and Lucy watch Rogue's shadow because it's glowing but then the glow fades away. Natsu laughs as he watches Juvia and Gray interract.
