Summer Pool Twilight Prologue (Abridged)

Tokyo is surrounded by really tall walls. Natives have no idea what's outside, and most of them aside from a certain subset have no idea about the game happening every day that divides the city.
Meta Theater, maybe
Christine: A game is something with rules and and players who perform their assigned roles.
Leanan Sidhe: Games mercilessly divide people into winners and losers.
Barong: Games are meant to entertain someone!
Nyarlathotep: Games are worthless on their own! But if you're doing it for fun? Acting! Gambling! Playing! Tricking!
Christine: Anyways, thank you for visiting the Yurakucho Theater. We are the Entertainers, those whose duty is to act out fiction to entertain the audience. Tonight we will be showing one incident from one of the many loops, a tale of a created bond that would not have been under normal circumstances. Maybe it's a common story script, but we Entertainers believe in that fiction's future. Fiction shows joy that hasn't existed yet... enjoy!

Shinjuku Chuo Park
Kengo: Thunder Kick! Okay, that one's down! Shirou, what's going on over there!?
Shirou: Evils, search!
Evils: Screee!
Maria: I don't see any more Strays here! Are we...?
Ryouta: Oh no there's one behind you!
Touji: Samurai save! Come on, MC!
MC: Grass Cutter! (bop)
Oni: OUGH! You, Master now...! (poof)
Contract! Might makes right!

Ryouta: Thanks you guys! Maria are you okay?
Maria: Y-yes. Thank you everyone!
Touji: Hmm. So we had Kengo act as a decoy.
Shirou: It's cool, the Evils say the Strays are all gone.
Dark Angel: Thank you, Summoners. The angel troops shall withdraw now. Be careful, all of you. (flies off)
MC: Okay, break time / That was rough / He ditched us!
(A) Kengo: Eh, I haven't punched people enough yet. This ain't nothing for you and me!
(B) Ryouta: I was worried for a bit, but it worked out thanks to you!
(C) Shirou: No MC, that's rude!

Maria: Allow me to thank you all for helping again. I know we came to investigate Strays attacking people walking around here, but I wasn't expecting to be actually attacked...
Kengo: So what are we gonna do with them? Punish them more?
Maria: Oh no this is enough. The Missionaries will take custody of them for now. We are all about opening our hearts to those with nowhere to go, and as proxy guildmaster I should model that belief too.
Shirou: Ryouta told us about things. We support your endeavors.
MC: We help the helpless! / Contain the Game's damage! / Soooo how about some gratitude, ehehe?
(A) Ryouta: Yep, that's our policy!
Shirou: Indeed. We should deepen our alliance with the Missionaries.
(B) Shirou: Yes, our policy is to protect people from abusing the app game and attacking people.
Kengo: Terribad problems have been popping up a lot lately. Ask me and MC for help whenever! Oh and these guys too I guess.
(C) Maria: O-oh, of course we can put something together later fo--
Shirou: Oh my god MC you can't make jokes like that! Please forget they said that!

The App Game is played inside Tokyo where people split themselves into guilds based on beliefs and fight over Portals and territory. Which belief is the strongest? App magic makes physical damage occurred in Enclosed Areas revert to nothing, memories and PTSD effects not included. Lately more cases of people taking advantage of this trait of the game for crimes like blackmail and theft have been increasing.
Shirou: A lot of crimes with Strays lately...
Touji: Yes, the police have been getting more reports of such too.
Shirou: I hope our actions are helping at least.
Ryouta: Why can't we all just eat up and be friends? That'd be great.
Kengo: But we gotta be prepaid for anything! We need physical strength, man!
Shirou: That's PREPARED for anything, you language mangling moron!
Touji: Cases are rising for sure though. We should stay focused. I have police authority, so the responsibility is heavy on me.
Shirou: Yes... the true danger is in how the app is used. You all remember what's happened so far.
MC: Yeah! We need to figure out the app's secrets! / Eh, let's save it for later.
---
(AB) Shirou: Yes, that's why we formed the Summoners. No repeats of those tragedies!
(C) Shirou: Yeah...it still scares me to think back on it all. But we can't forget our goals.
---
Ryouta: Anyways, let's go for ramen!
Kengo: I'm in!
Touji: I have training to...actually, I'll come too.
Shirou: We still have curfew, but I'll come along as well if we'll be back in time.
And so the gang sallies forth, still innocent and ignorant of everything... 

Kabukicho
Suzuka: I've been hearing about the Summoners lately. I'mma beat them up if they think of starting shit on Outlaws turf!
Gyoubu: Haha, lighten up Lady Tate Eboshi. You shouldn't get mad over every little thing.
Suzuka: Would you stop being so laid back while I'm all worked up? A buncha thugs have been coming in from around Ikebukuro and--
Gorozaemon: Hmmmm. Well I can't fault you for worrying, miss. You shouldn't wind yourself up too much though. That's what ayakashi go for when they come for you.
Suzuka: WHO'S SUDDENLY BEHIND ME
Gorozaemon reveal!
Gorozaemon: S'up, Iyo-Matsuyama Tanuki! How's the 808 Tanuki doing?
Gyoubu: ...huh! I never thought I'd see you of all people.
Gorozaemon: Ehh, don't worry about it too much. I'm just here to enjoy a new life in retirement.
Gyoubu: Suzuka, could you put your sword down? I go way back with them.
Gorozaemon: Ever the mother hen, you. Mweheh. Catching up on old stories is great and all, but I came to talk about something else...

Some alleyway
Ibaraki: BROOO! Did you promise to do crap without thinking about it again!?
Shuten: What? I was asked to do somethin' and I just answered. What's wrong wit' that?
Ibaraki: But it's summer vacation! You could do just about anything besides baseball! Are you gonna spend all that time as a pinch hitter in practice games?
Shuten: Our school baseball team said they don't have enough teen embers or somethin' for the tournament. They asked me fer help in makin' summer memories.
Ibaraki: But what about MEEEE?
Shuten: Oh are ya askin' me to go wit' you?
Ibaraki: UGH can't you make some priorities when it comes to people?
Gorozaemon: Still stubborn as ever, aren't you Boss of Mt. Ooe?

Shuten: !!
Ibaraki: Bitch you talking shit about Bro!?
Shuten: No, Ibaraki down. Very bad.
Gorozaemon: No it's cool. Seeing the young be so lively makes me happy. But anyways I came to ask you something.
Shuten: Shoot. I'll answer anyone who asks.
Gorozaemon: So stubborn. Anyways I'm looking for someone who goes to your school...
Kabukicho
Suzuka: Who was that mysterious weirdo? They suddenly disappeared right after saying their thing!
Gyoubu: Mysterious is right. Anyway you're an oni from Wa no Kuni so you should have heard SOMETHING about them at least.
Some alleyway
Shuten: Oh right you never met them before. Eh the young wouldn't know anyway. But still, I'm sure you've heard of something about the Wa no Kuni Youkai at least.
Ibaraki: Wait was that the Legendary Motorbiker and Head of the Night Parade!? 

Shinjuku dorm, nighttime
MC's room
MC: Ugh it's hot. Wait someone's here! / (summon sword)
---
(C) Gorozaemon: Hahaha, wow that was impressive guesswork!
---
Gorozamon: S'up. You MC?
MC: AAAAAA / Yes??? / Attack!
(A) Gorozaemon: Yes! YES! I love that reaction!
(B) Gorozaemon: Wow, you're brave! Scaring you is gonna be great!
(C) Gorozaemon: Hey wait, stop? I didn't come to pick a fight.

Gorozaemon: Sorry to scary you, I'm just like that in wanting to see how much guts you have. And sorry to interrupt when you're trying to go to bed but--
The gang barges in!
Shirou: MC ARE YOU OKAY I HEARD SOMETHING
Ryouta: OH MY GOD WHO IS THAT
Touji: Begone intruder!
Kengo: Hey bastard you got guts trying to, uhh, what was the word again
Shirou: It's ambush you dumb meathead! Anyways, who are you!?
Gorozaemon: Wow look at all these connections you've made. But where was I? (theatrically bows) I'm a messenger from the Yurakucho guild and former youkai head from Wa no Kuni. Sanmoto Gorozaemon at your service.

Later
Gang: An invite to the Twilight Night Pool Party hosted by the Yurakucho guild?
Gorozaemon: So you guys have been making a name for yourselves lately, though I haven't personally heard. The party's investor wants to invite you guys along with the Berserkers and Tycoons, and I was sent to deliver the invite. And then I felt like entertaining myself a bit too much...
MC: At this time of night? Really!? / Oh my god a celebrity invite!
(AB) Gorozaemon: Haha, don't have a cow dude! Is that what kids say these days?
Ryouta: Huh. Well anyways we've really been invited to that party?
(C) Gorozaemon: Yup. There's gonna be other VIPs, but they really want you there, MC. I got curious about what you were like, so I tried to have a little fun! Super sorry, yo!
Kengo: O-okay. Well MC is strong so I get how that feels.

Shirou: I feel like I've heard about the Yurakucho guild before. Maybe.
MC: It might be a trap. Being called by name is a little freaky. / A celebrity party...wow.
---
(C) Touji: Wait, you're really thinking of jumping in?
---
Gorozaemon: Well you'd be right to be on guard. It's sus to me too, honestly.
Ryouta: Why would you say that!? And who are the Entertainers...?
Touji: I've seen that name in old police records. I believe they are a guild based on a theater troupe. Their stated principles and beliefs are unknown, though I knew that already...
Gorozaemon: Mwehe, oh we just want to keep the game interesting and direct things regardless of allegiances. I guess I'm sort of the same now that I say that, because back in Wa no Kuni I'd take whatever youkai was around along with me to scare humans. Scaring humans is great! Which means I don't know what's going on underneath the surface this time. Because knowing the script ahead of time is boring! Again I'm here as the Entertainers' new errand runner. If something is up with the party, feel free to smash it!
Kengo: fREAK.
Touji: ...you guys don't believe them, right? They sound just like thrill criminals.
MC: Touji makes sense / SUS / I'm getting chills for some reason

Kengo: Meh, if something's up we can just punch it to pieces.
Touji: Hmm. Are you saying it's a chance to get info on a guild we haven't seen before even if it's risky?
Shirou: Yeah, regardless of their motives, if they're saying MC is someone to acknowledge we might have a chance to ally with them.
Ryouta: Oh my god can you imagine the FOOD!?
MC: Charge on through! / Okay let's RSVP yes / All the food!
---
(A) Kengo: Yeah boy! Let's kick some ass!
(B) Touji: MC if they break the law in any way I am going to use my government authority.
Shirou: Wait let me negotiate first. It's my job to probe them from within.
(C) Ryouta: Yes we so have to go!
---
Gorozaemon: Mwehe, nice. I'll go inform the investor. Oh, I should advise you guys of something as a former youkai boss about this bright party. Every light has its shadow and true terror lurks further within. This world has unbelievable things in it, and you better believe that! HAHAHA!
And then the day of the party came!
