Season 2, Episode 2:
Hot Line
The Kingdom of Science must match wits with Tsukasa’s scout, Homura, so that they can deploy their newly built cell phone in the Kingdom of Strength's base.
Feats of Science:
- Flash grenade.
- Black light.
- Fluorescent mineral powder.
Tropes:
- Battle of Wits: The Kingdom of Science vs Homura, using the power of radio.
- Big Damn Reunion: Radio version.
- Blinded by the Light: The first trap sprung on Homura is a flash grenade.
- Chase Scene: A cerebral one with Homura, because she's too fast to catch.
- Catching the Speedster: Homura can only be caught by luring her into a predictable position.
- Designated Girl Fight: Subverted. When Kohaku attacks, Homura runs instead of engaging. Then, the entire village tries to capture her. Played straight when Kohaku is the one to capture her out of the air.
- If You Kill Him, You Will Be Just Like Him!: In this case it's pragmatic as well as moral - killing people makes it harder to recruit them to your side.
- Reformed, but Not Tamed: Magma wants to smash the statues of future Kingdom of Strength recruits.
- Sleight of Handiness: Gen tricks Homura into attacking a fake radio transmitter at the top of a tree.
- The Bus Came Back: Taiju and Yuzuriha are back!
- Tracking Device: Senku covers Homura in fluorescent mineral powder so they can track her movements with a black light.
