Houka was in Ira's office. Ira was sitting at his desk.
"Ira, I have a bad feeling that our Shinra-Koketsu plan might not work."
"What makes you say that? Nice mask, by the way."
They heard Shiro screaming from downstairs.
"Just a feeling. And thank you."
They went into SCOURGE's basement to find Shiro screaming like a dying animal. He had accidentally infected himself with necrotizing fasciitis.
"Shiro, you goddamn idiot. Alright, time for Plan B. Ira, you stay here with Shiro. I'm going to kidnap Ryuko and torture her until the police come. They're going to arrest you and Shiro, assuming he's not dead by then. You're probably going to get the death penalty for your numerous crimes, so you should take a plea bargain and testify against every criminal you know in exchange for a reduced sentence. You have to be alive for Plan B."
"Aight."
"OH GOD, IT BURNS! MY SKIN FEELS LIKE IT'S MELTING!"
"Shut the fuck up, you stupid-ass nigga."
"Also, Plan B depends on our secret project hidden here to stay intact. Protect it with Shiro's life."
"FUCK YOU!"
"You're probably going to die anyway, Shiro. That's what happens when you infect yourself with mutated flesh-eating disease."
Houka walked to Ryuko's house before she and Mako came home from work and hid in the closet in her living room. Aikuro came over to watch a movie. After Aikuro had gone home (which was a large building formerly owned by Dotonbori Robotics, which was owned by Kaneo Takarada; Aikuro thought that if they changed their name to something simpler like "DTR", they wouldn't have gone out of business; of course, Aikuro had named his police car "The Naked Sun", so he probably had somewhat poor naming skills), and Mako had fallen asleep, he jumped out of the closet and knocked Ryuko unconscious, carrying her to SCOURGE's basement. He also left a note for Mako on the couch, telling her where he had taken Ryuko.
After tying her up, he carved a small "X" into her right eyelid. That woke her up.
"FUCK! MY EYE!"
"I didn't cut you enough to blind you, Ryuko. I just want you to remember our time together."
A few hours later, after Houka had burned the back of Ryuko's left hand with a lighter, Aikuro and what can only be described as an army of HCPD officers, even the ones who used to look down on her for being a rookie, stormed SCOURGE and arrested Houka, Ira, and Shiro. Shiro was later taken to Honnouji's hospital, where the doctors saved his life. Ira testified against several criminals, including Kaneo, in exchange for a reduced sentence. They were all convicted. Houka was handcuffed and was being escorted back to his cell, when he lost consciousness.
He woke up in a place he didn't recognize. Doctor Houka Inumuta had found himself in a strange place, to put it lightly.
Note: And that's the end of the Earth-2 prologue! That's 50% of the entire prologue finished! The chapters after this will be set in Earth-3, which is exactly like the anime's Earth (Earth-1), but their Houka Inumuta is..."different". And by "different", I mean, "completely batshit crazy and has an unhealthy obsession with Nonon".
