Operation Happy Halloween (Second half)
Hard Chapter 2
Hero Club room
Gi: Munch, munch... No doubt this was a big haul, but it kinda feels like something's missing.
Su: We made lampions out of pumpkins, dressed up in costumes and were given so many sweets, but it's still not enough?
Gi: Costumes...? Yeah, about the costumes, something more like, you know, some more trick or treat kinda stuff... oh!
sS: Munch munch... Heffing hah waf hn, mhm~? Hamn... Nghnnh!*
It: Sonoko-san!? Did it get stuck in your throat!?
Su: Sonocchi, are you okay!?
Gi: Don't wolf down the chakinshibori like that. Here, have some tea, drink up.
sS: Nguh, nghuh... Haah! It was so delicious that I got a lump in my throat~.
Gi: Don't you mean that it clogged your throat?
It: T-that was nerve-racking...
Su: Gin, you sure are level-headed at times like these...
Gi: I'm used to it 'cause of my little brother. Looking at Sonoko kinda makes me think of him.
sS: Goo-goo.
Gi: No, cut that out already.
sS: Boohoo!
Su: Anyhow, Gin. What did you think is missing?
Gi: Oh, right! The costumes made me remember! The "trick" part of trick or treat!
sS: Ah, now that you mention it, the hair treatment in the bathroom is about to run out~.
Gi: I said trick, so why did you play stupid about the treat part? You've gotta explain that to me later, Sonoko.
It: Trick, you mean... Gin-chan, did you want to play pranks?
Gi: Exactly! Trick equals pranks! I wanted to cause some mischief!
Su: ...Is that something you should declare so boldly...?
It: But come to think of it, Onee-chan and the others gave us all the sweets without any hesitation.
Gi: I mean, I really appreciate that and everything, but Halloween's just not Halloween if you don't get to play pranks!
Su: Right... There was this terrifying custom for those who fail to give out candy to be made a target of mischief.
sS: Terrifying~.
Gi: As such, we're now switching to Operation Happy Halloween phase 3!
Su: Gin, you can't mean...
Gi: Muhuhu... Gimme sweets or you'll get pranked!

*She probably said "dressing up was fun, huh?" here.
