Plot
As Leo recaps what has happened since the events of Earth's Last Stand, it seems that with all of their enemies having either fled Manhattan or been destroyed, the Turtles are able to enjoy a celebration under the full moon as, joined by Casey, April is promoted to Kunoichi by Splinter, giving her a ceremonial tanto to signify her new status, along with her jumpsuit from her space adventures being repainted black with a yellow stripe down the sides of the arms, torso, and legs.

During their first patrol together, the Turtles and April are attacked by a young sorceress by the name of Shinigami, who manages to escape after stealing April's tanto. Frustrated by losing her tanto so soon after getting it, April and the Turtles begin searching for Shinigami after Splinter believes she could be a new ally of the Shredder. Leo patrols in the Party Wagon, Donnie from the Channel 6 building, and Raph in the Shellraiser, while Mikey stays at the lair. April watches Shredder's old lair, where she sees Shinigami enter and follows her, spotting someone wearing the Kuro Kabuto on Shredder's throne, soon revealed to be Karai.

As April reveals herself, the Turtles soon join her. However, Karai explains that Shinigami is an old friend from Japan, and she's no longer under the brain worm's control, wanting to destroy Shredder's criminal empire in NYC, rebuild the Foot to it's former glory before being corrupted by Shredder, then taking down Shredder himself, once and for all. April confirms it thanks to her psychic powers and the Aeons' gift, and though the Turtles offer their support to Karai's fight, she wants to handle this her way. However, April still wants her rematch with Shinigami to get her tanto back and Karai agrees to it.

At first, Shinigami has the advantage over April, but then April's anger is amplified by the Aeons' gift, causing her to fire psychic blasts that crack the glass around Shredder's old lair before Shinigami is able to best her. Karai calls off the fight before things escalate, then has Shinigami return the tanto anyway, but April, still infuriated, begins to draw her tanto as the Aeons' gift continues to amplify her rage, before Donnie is able to calm her down and remind her not to give into her anger. With that, the Turtles leave, but remind Karai she still has them to turn to for help if she needs it. No one notices a Foot-bot climb onto the outside glass to peer into the room.

Back in the lair, April vents her frustration to Splinter, who decides to teach her an advanced move known as The Dragon's Tail.

Back with Karai and Shinigami, they arrive at a martial arts store that is actually a front for Shredder as he keeps a large cache of munitions in the back. Tiger Claw, Rahzar, and Fishface, watch from a nearby rooftop, before following Karai and Shinigami inside, where Karai makes it clear to Tiger Claw that she's taking down Shredder and his whole crew for everything they've put her and New York City through, but despite her and Shinigami's best efforts, Shinigami is defeated by Tiger Claw who put her over his back and defeated her with a combination of his jetpack and the ceiling. Then he gets Karai to surrender, but not without Karai sending a text message for help to the Turtles first.

As they are kept hostage, Karai manages to free herself, but is quickly overpowered by Tiger Claw, who prepares to kill her before the Turtles and April intervene, freeing Shinigami, allowing them to give Shredder's minions a good beating. However, while fighting Leo and Karai, Tiger Claw throws Karai into a crate, where Karai's anger causes her mutant self to surface, transforming her arms into her mutant versions to try and tie up Tiger Claw, but he is able to overpower her and Leo. That's when April comes in, drawing Tiger Claw's attention before delivering The Dragon's Tail right between his legs, causing him to crumple to his knees in agony, before Mikey drops a smoke bomb to allow the Turtles, April, Karai, and Shinigami to escape, leaving Tiger Claw, Rahzar, and Fishface to discover that the Turtles have rigged the entire warehouse to blow with explosives, leaving them unable to escape before the charges blow and wipe out Shredder's munitions cache.

Back in the lair, Karai and Shinigami apologize to April about the earlier fight, April and Karai then shake hands and make amends with each other. Afterward, Splinter speaks with Karai, but she assures him that this is her fight as she's grown up now, and she needs to handle Shredder her own way. Splinter voices how proud he is of her as she leaves, and the Turtles agree that they have to be ready when Shredder returns since their fight with him is not over.

Elsewhere at a condominium overlooking the city with Rocksteady and Bebop as guards, Tiger Claw returns to speak to the Shredder, who is being cared for by Stockman-Fly as the injuries he sustained from losing his fight with Splinter have left him confined to a hospital bed hooked up to several life-support machines with his face wrapped in bandages. As Tiger Claw reports the loss of the weapons cache along with Karai and the Turtles being responsible for it and Karai's decree to wipe out the Shredder's influence in NYC before taking him down for good, Shredder is able to utter out that if it's a war Karai wants, it's a war she'll get. Stockman-Fly hooks up an I.V. loaded with mutagen. As it flows into Shredder's body, his eyes open wide as the mutagen takes effect.
