Hot Line is the twenty-sixth episode of the Dr. Stone anime, and the second episode of the second season.


In order to get in contact with Taiju and Yuzuriha who are infiltrating the Tsukasa Empire, Gen's group performs a dangerous mission to place a cell phone in certain location. All while this is happening, Gen's group is pursued by the empire's scout Homura.

Plot Details

As Magma, Gen, and Chrome take advantage of the detonating Sonic Bombs, Magma complains that it'd be easier if they simply capture/kill Homura. To that point, Chrome snaps that if they knew her location they'd be able to do it. Gen details that the Tsukasa Empire's main concern is gun powder and the explosions from the detonated Sonic Bombs would distract Homura long enough to investigate. From the observatory, Suika spots Homura and briskly Kohaku sets off to tail her.

Immediately when Homura arrives at a spot where the bombs were detonated, Kohaku ambushes Homura with a sword attack, but with her adroit reflexes dodges the move. Homura's adroitness were a product of her years of training in gymnastics. Pursued by Kohaku, Homura refuses to give in and plans to exhaust her purser by draining her energy by keeping her talking, but is left astonished how she can keep up with her. The pursuit leads the two closer and closer to the village and when this is learned, the villagers are order by Kokuyo to take shelter. It's then that Senku intercepts the two and uses his newest invention the Flash Bomb to blind Homura. An explanation of how Flash Bombs are made is given by Mecha Senku. Senku then captures Homura, but moments after escapes and evades being captured again. Once at a safe and high point atop of a tree branch, she names off all of the villagers in her sight. She then suspects the missing Magma, Chrome, and Gen are taking something to the empire and storms off. With Homura gone, Chalk is tasked with trying to track her scent, but is unable to do so. The villagers panic stricken over the consequences if Homura would capture Magma, Chrome, and Gen and then destroy the cell phone they're carrying the plan would fail. Therefore, Senku reveals another new invention of his to help track Homura.

Using powered scheelite that he secretly covered on Homura, Senku uses his new invention a "Black Light Gun" to shine a visible light on Homura's tracks. As the pursuit group follow Homura's tracks, Kohaku asks if she could have permission to kill Homura, but Senku asks if she ever has killed a human before. In response, Kohaku answers that she never has, but is resolved to do it despite any hesitance she may feel. On the other hand, Senku has faith in those entrusted with the Cell Phone, those of whom, continue their venture to the Empire making sure to do routine maintenance check ups on the Cell Phone to make sure it still works. During a check up, a single ring comes from Cell Phone rings once signalling the group that Homura is on her way. Underneath a small cavity, Senku informs Kohaku and Kinro about how they'll perform a pincer attack against the unsuspecting Homura. Meanwhile as dawn starts to break, Homura sitting atop a tree notices the scheelite glitter placed on her and the tracks she left from it. Because of this discovery, she washes herself off by a local river, making it impossible for Senku's group to track her anymore. Gen also sends ringtone morse code to Senku's group detailing their current location. Cross referencing this new information, it's suspected that Homura has already caught up to Gen's group and is tailing them.

Elsewhere, the assumption of Homura locating Gen's group is proven right and she falls for a trap set up by them. With Homura recaptured, Gen's group continue to the Empire. Once group reaches their destination, they find a large gathering of petrified statues with numbers written in blood on their foreheads. The lowest number written on the statues is 33 and Gen figures that the empire currently has 32 people in their Empire. Magma comes up with an insidious idea to break the arms and legs of the statues to make them incapable of fighting. Right when Magma was going to go through with this, Gen stops him. Understanding how savage Tsukasa is, Gen considers himself weak for being unable to kill or allow someone to kill other humans. Chrome then speaks in defense of Gen, claiming he's not weak and that their goal is one of a higher purpose. By dusk, Gen's group reach the trade off point which is at Senku's "Fake" grave and into nightfall set up the cell phone. Because of Magma's impulsive nature, he creates a loud noise that draws the attention of Ukyo whose astute hearing picks up the sound and pursues Gen's group.

The following day, Senku waits in his hut with Suika and Kohaku, until Taiju and Yuzuriha anwser it on the other side.
