Blade and PistolsVideo Summary: Do not go tamely into Hollows...
Story Description: Anby landed safely in the Hollow and soon met up with her colleague Billy. However, without a Carrot, the two faced the dilemma of not being able to leave the Hollow.
- Short Haired Girl: Tracks, platforms, and carriages... This is the old metro junction. If that's the case, then this must be the Cretan Hollow.
- Short Haired Girl: Good. Headset still works, and the recording function is normal.
- Short Haired Girl: Ahem. This is Anby Demara, a member of the odd-job agency, the "Cunning Hares." I accidentally fell into a Companion Hollow.
- Anby: I don't have a Carrot or Proxy support. Probability of getting lost in the Hollow is at 96.4%.
- Anby: I will be making a voice log of my experience. Let it serve as evidence for future investigation in the case I am killed or turned into a monster by the Ether.
- Anby: Anby's Hollow Survival Log #1: From my surroundings, I can confirm this is the old metro junction area of the Cretan Hollow.
- Anby: The metro Hollow's terrain is inherently complex. My chances of being rescued will be reduced by 37.8% if I don't consider my next step carefully.
- Anby: If anyone doubts the nature of the Hollow's spatial distortions, please use my recording as proof of their danger. Please don't enter a Hollow unless you are a professional Investigator, otherwise...
- Billy: —Ah, there you are, Anby! Great!
- Billy: I knew you'd be okay—
- Billy: Whoa whoa! Hey, what's gotten into you?! You almost cut me!
- Anby: I've met another being of reason. He looks a lot like my colleague: Billy Kid.
- Billy: What are you talking about? It's me! Billy!
- Anby: An Investigator has previously encountered Ethereals who can mimic human speech and behavior.
- Anby: The Investigator rescued the Ethereal pretending to be their teammate, but once they got out of the Hollow, it revealed itself.
- Anby: The city made a huge sacrifice but it was unable to defeat the monster. It was only thanks to a courageous Investigator who gave his life to drive the monster back into the Hollow that the danger was averted.
- Billy: Come on— The Ethereal would be done for the minute it left the Hollow!
- Billy: Wait, isn't that the plot of that movie that was in theaters not long ago!?
- Anby: ...There was a long list of victims involved in the incident. I read all their names.
- Billy: That's called a cast list!
- Anby: Question: Who would you most like to have dinner with?
- Billy: Huh? Dinner? Of course... that'd be the big screen superheroes, the Starlight Knights!
- Billy: Wait wait wait! Put your blade down, I'll tell you!
- Billy: ...It's really the late night drama actress from "Oh~ Sweetie," Monica...
- Anby: All clear. The individual has been confirmed as the real Billy Kid.
- Anby: Meeting Billy Kid increases my chances of survival by over 67.8%. I'm glad you're okay, Billy.
- Billy: I told you I'm me!
- Billy: ...It's been a while since we fell. Nicole must be trying to come up with a way to get us out from the outside.
- Billy: But will she be willing to pay for the help? You know how Nicole is, hahaha...
- Anby: Based on Nicole's tight-fisted spending habits, I'd say your original analysis is likely correct.
- Billy: Damn... Now you've got me worried.
- Billy: Let's not get carried away. We have to work together to get through this.
- Billy: As usual, you take the front, and I'll provide fire support from behind.
- Anby: Right.
