Billy: Grow in the midst of battle...
(Talk to Billy)
Billy: Manager, good timing!
Billy: I watched the movie you recommended.
Billy: The plot was really complicated. I've almost forgotten what happened...
Billy: But I still remember one quote!
Billy: "The only way for a true hero to grow is in the midst of constant battle."
Billy: That's so cool...
Billy: I need to grow through constant battle too... to become the best Starlight Knight!
Billy: Like exploring the most dangerous, terrifying, and ferocious Hollow in New Eridu...
Icon Dialogue Talk You mean Hollow Zero?
Billy: Yeah, that's the one!
Icon Dialogue Talk Such a Hollow doesn't exist.
Billy: What are you talkin' about!
Billy: There's Hollow Zero!
Billy: I bet an awesome Proxy like yourself knows a thing or two about Hollow Zero!
Billy: Like... a way for me to get into the Hollow?
Icon Dialogue Talk You guessed right.
Icon Dialogue Talk I've got a way in, and it's legal.
Billy: I knew it! I'd expect no less from you, Manager!
Billy: So... Next time you get the chance to visit Hollow Zero, would you take me with you?
Billy: I'm strong. Put me to good use!
Icon Dialogue Talk Of course!
Icon Dialogue Talk Alright, let's see just how useful you are.
Billy: Alright! It's a date!
Billy: I'll be waiting, Manager—
(Idle)
Billy: Darn it, I'm already all fired up!
(Talk to Billy again, optional)
Billy: What should I get ready before Hollow Zero... I should watch Starlight Knight again, start to finish!

Explore Hollow Zero with Billy

Icon Dialogue Agent Tracked Step Description

Billy is ready, so we should head into Hollow Zero with him to explore!

Deploy Billy in your squad and trigger a Trust event near the second floor rest area to complete (apart from Qualification Assessment stages
(Trigger the Pleasant Partnership event in Hollow Zero)
Fairy Smart Intervention: "Scanning for area data..."
Fairy Smart Intervention: "Low Ether activity detected in this area."
Fairy's broadcasting...: Billy: "It's rare to find such a peaceful spot. Should we take a break here?"
Fairy's broadcasting...: Billy: "Hmm? Wait a minute, Manager. This place seems..."
Fairy Smart Intervention: "Picking up signals from multiple unidentified individuals approaching us... They've surrounded us."
Fairy Smart Intervention: "These unidentified individuals are highly likely to be Hollow Bandits."
Fairy's broadcasting...: Hollow Bandit: "Stop right there! Your money, or your life!"
Fairy's broadcasting...: He even has an insulated thermos in his hand.
Fairy's broadcasting...: Hollow Raider: "Hand over everything valuable, or I'll feed you to the Ethereals!"
Significance of Hairstyles: You were planning to rest here, but now you've stumbled upon a bunch of Hollow Bandits.
Bandits who can operate in this area must be anything but ordinary... right?
You decide to...
Wait and see what happens.
Wait for a chance to escape.
Fairy Smart Intervention: "The bandits' encirclement is flawless, leaving no route for escape."

Trust "Hollow Bandit"

Story Description: You came across some Hollow bandits who intended to sell Eous, but Billy protected you at the critical moment...


Billy: Are you the legendary Hollow Raiders? The ones who hide in the Hollows for investigators or other Raiders to rob?
Billy: Well if so, you've obviously targeted the wrong people. We're broke, you see. Even if you sold off all my worldly possessions, you'd hardly turn a Denny.
Billy: Just look, I haven't even been doing my regular maintenance, I'm starting to rust...
Hollow Bandit Leader: Shut up already! You look familiar. You must be a popular model, right?
Hollow Bandit Leader: Then your parts can be scrapped for good money. And if ya keep blabbering, I'll send you to the scrapyard!
Icon Dialogue Talk It'd make more sense to sell him as a full package.
(ProtagonistProtagonist): (‍Ehh...Ehh... / Hm?Hm?‍) It'd make more sense to sell him as a full package.
Billy: Nice one, you've got a good eye. A premium model like me deserves to be sold whole—
Billy: Wait, wait! Why am I helping you get rich by selling me off!
Icon Dialogue Talk Want me to put a phone call in to the hotline of the robot protection society?
(ProtagonistProtagonist): Want me to put a call in to the robot protection society hotline?
Billy: Thank you! But if the Society for the Protection of Robots does come, they'll be taking us both away.
Billy: Whatever, Hollow Raiders are no match for a Starlight Knight like me, anyway!
Hollow Bandit Leader: Huh? This Bangboo looks pretty sweet, too. Should fetch a good price.
Just as the bandit is about to pick the Bangboo up, Billy suddenly stands between the two—
Billy: Hey pal, make all the scrapyard jokes you want.
Billy: But if you want the Manager, you'll have to go through me first.

Trust Rank Friendly Trust increase with Billy Kid
Significance of Hairstyles: Out of nowhere, Billy says something impressive.
Could it be a line he learned from Starlight Knight...?
(During combat)
Billy: Seeing as yer being so stubborn...
Billy: I'll just have to prove it with my actions, then.

Trust "Billy's Secret"

Story Description: Billy successfully drove off the Hollow Bandits, but his hair got wet from their secret weapon... Interestingly, his altered hairstyle seems to have reminded the bandits of something.


Hollow Bandit Leader: Damn it! Y—You guys aren't just ordinary Hollow Investigators!
Billy: That's right. We're far from ordinary. I already told you, we're — completely broke Hollow Investigators!
Hollow Bandit: What should we do, Boss? We can't beat these guys...
Hollow Bandit Leader: Hmph, idiot. I've got a secret weapon against robots—
The bandit leader pours the thermos he was holding over Billy's head with one single swift movement.
The hot water drenches Billy's hair, slowly running all the way down his body...
Icon Dialogue Talk You okay, Billy?!
(ProtagonistProtagonist): You okay, Billy?! No short circuits, right?
Billy: I'm fine. Turns out their secret weapon against robots is just water... Unfortunately for them, I'm certified waterproof.
Billy: Wait a minute... My hair, it's drooping!
Billy: So, this whole time, your real goal was to deal a fatal psychological blow by ruining my hair!
Icon Dialogue Talk Are you trying out bangs, Billy?
(ProtagonistProtagonist): Oh, decided to give bangs a try, Billy?
Billy: No! It's strong! It'll go back!
Icon Dialogue Talk I'm looking forward to your new hairstyle!
(ProtagonistProtagonist): I'm looking forward to your new (‍hairstyle.hairstyle. / hairstyle!hairstyle!‍)
Billy: I'm handsome with any hairstyle, right?
Hollow Bandit Leader: Why does this robot look so familiar? A red jacket, white hair... Something seems missing though...
Hollow Bandit Leader: Hang on. Don't tell me you're the legendary—
Billy: That's right. You're looking at none other than... a Starlight Knight!
Billy: You know the old saying, "Bad guys always die cuz they start monologuing"!
Billy: Sometimes you should just keep your mouth shut.
Hollow Bandit Leader: Wahh! Run! We don't wanna mess with this guy!
The aggressive bandits suddenly flee in a panic like mice fleeing a starving cat.
Icon Dialogue Talk Did you notice anything strange about those bandits?
(ProtagonistProtagonist): Did you notice anything strange about those bandits? Like they were hiding something...
Billy: Really? They were probably just intimidated by the bravado of a Starlight Knight!
Icon Dialogue Talk You make a good point.
(ProtagonistProtagonist): You make a good point.
Billy: Right? Right! You get me.
Icon Dialogue Talk Hmm, are you hiding something?
(ProtagonistProtagonist): Are you hiding something from me?
Billy: I've got lots of secrets. Which one do you want to know about?
Billy: Everyone has a past. You're no different, right?
Billy: You can't change the past, which is what makes the present and the future far more important.
Billy: Speaking of the present...
Billy: Have you got a hair dryer on you by any chance? To rescue my soaked hair!
Icon Dialogue Talk Who on earth would bring a hair dryer into a Hollow...
(ProtagonistProtagonist): Who on earth would bring a hair dryer into a Hollow... And didn't you say you're waterproof? It's not like you'll short circuit.
Billy: I might not short circuit, but my hair is an important heat sink and I gotta cool down somehow while I'm operatin'! The moisture hinders the heat dissipation!
Billy: Let me just think up a way to blow-dry my hair in here... Oh! Maybe if I run fast enough, the air will naturally dry it!
Billy: Let's give it a try! You stand still and don't move. I'll run circles around you—
Icon Dialogue Talk We've strayed a bit off topic...
(ProtagonistProtagonist): We've strayed a bit off topic... Also, wouldn't you generate more heat when you run?
Billy: Wow, check me out! I reckon it's really working. Who knew I could come up with such a genius solution like this!
Billy: Hey, don't just walk off. Wait for me—
