First major RP attempt, I'll give it a go

Theo: (arriving in his dorm) "alright. should be this room..."

(as he walks into the room, he finds 3 Kirbys already there, an orange one, who is leaning over to talk to a purple sitting on the sofa, and a gray Kirby, sitting on the bottom of the opposite sofa. The dorm itself has a main area where the Kirbys are sitting, a kitchen in the back, and a couple of doors you presume lead to bedrooms. There is also a hat rack and what appears to be a weapon stand on the wall, however both are empty. The Kirbys turn around to face you after they heard the door open)

Purple: ah, here's the last member of the dorm!
Orange: hey there!
(Gray doesn't say anything but still waves),

Purple: right. Introductions are in order, my name is grape, that's citrus over there (they point at the orange Kirby, who puts their hand up in acknowledgement.) and that's coal over there (they point at the gray Kirby, who just sits there.) ... They are a bit quiet but they are alright. And... what's your name? I didn't see it on the assignment list, sorry about that...

Theo: "Oh hey. I'm Theo."

(yea DW I knew that beforehand)
Coal: grape seems kinda down, maybe we should invite them over here?

Theo: alright. Hey Grape! Come over.

Grape (snapping out of whatever they where doing): oh, alright. (Comes over and sits down opposite coal)
Coal: you seem... Odd. Are you alright?
Grape: yea, I'm fine.
Coal: alright... (Changing the subject) So, what do you think our first class will be like?
Citrus (shouting across the room): well I think it will be great!
Grape: they usually do an assembly first to explain to the new students, then it's one class in each type, so we get used to all four.
Coal: I'm glad that is the case. I don't want to be locked out of the others, just because I like swords.
Citrus: order up! (He comes into the room holding 2 plates and gives them to Theo and coal) I'll be back in a second with grape's and mine.

Theo: Thanks, Citrus. Anyway, I just hope our classmates aren't jerks.

Grape: oh yea. Honestly, I think jerks aren't much of a worry as what happened yesterday.
Citrus: (coming back) yea, I think we got this.
(There's a knock at the door)
Citrus: really? I just sat down!
Coal: I have this. (Opens the door)
(There is a light blue Kirby at the door)
Light blue: greetings. I am the headmaster. You where supposed to meet me at assembly, like the others, but there is a matter I need to discuss. May I come in?
Coal: of course.
Headmaster: so. Of course, the events that occurred last night where atrocious. Never in my entire 30 years of working here have I heard of new students being attacked on the first night. However, after discussing with team Kirby, who arrived a few hours before the incident, they said that they wanted to tell the others what happened during the assembly, and give kudos to you for your bravery. Of course, as the effected party, you may not want this information to your classmates, so the choice is yours.

Theo: (whispers to the others) I don't think we should tell the others. I'm not really an "in the spotlight person". What about you guys?

Grape (whispering): I think that's fair. I mean, I don't think coal could handle the constant hounding to be honest. Citrus wouldn't mind but I think I would get bothered.
Grape (to the headmaster): thank you for the offer, but we feel this should be kept between us.
Headmaster: I thought you would say that. I'll go tell team Kirby. I swear, as much as they are the saviours of the dream Kingdom they can be so single-minded sometimes... Anyways, I'll be going now. I will let you finish your breakfast. Just make sure to be down by 10 for the assembly.
Citrus: will do!
Grape: be down at 10 for assembly. Got it.
(Coal simply nods)
(The headmaster leaves the room and closes the door)
Grape: I like them. I think it's great we have a stabiliser to team Kirby's somewhat chaotic, guns-blazing approach to life.

Theo: That sounds cool. Anyway Imma go amd get ready.

Grape: right, to answer your question, those where-
Coal: TEAM KIRBY?!?
Citrus: I think we are focusing on the wrong point, did they say TEACHING?!? Can I say "told you so" yet?
Grape: I'm checking my room, I think I need to check if anything was taken. Nice save Theo.
Coal: I'm going back to sleep (placing their stuff on the racks) I need to process what just happened.

Theo: me too, Coal. Night. (he climbs back into bed and passes out as soon as his head hits the pillow)

(hours later, coal's alarm clock goes off, waking you up too. Coal stretches before leaving the room to make breakfast, after you wake up, you follow them out, seeing citrus and grape are awake already, you presume they didn't sleep at all after last night's events, grape looks troubled but citrus seems quite happy considering he got thrown across the floor last night by someone who broke into the dorm. He turns around to see you and coal)
Citrus: oh, mornin' you two!
Coal: good morning.
Grape: hey.
Coal approaches the kitchen, about to start when citrus stops them)
Citrus: nope, I'm making breakfast for you two, especially after you saved our lives last night, with coal's shield and Theo's attack.
(Coal eyes grape in curiosity)
Grape (cheered up slightly): don't worry. Despite their complete incompetence in things like priorities and general survival, they are actually a great cook.
(Coal smiles and, after telling citrus what they want, walks to the sofa and sits down)
Citrus: so, what do you want for breakfast, Theo?

Theo: well, what is there?

Citrus: well, I didn't know what everyone would want so I kinda just bought everything for every possible breakfast I could think of before I came here. (he laughs somewhat awkwardly) So basically just whatever you want!

Theo: mmmmmmm... gotta go with fried eggs and toast.

Citrus: alrighty! I'll get working on it! Just take a seat and I'll tell you when it's done

Theo: ok!
(btw just clarifying Theo's appearence)

(sorry for the delay, I was busy yesterday)
(After you all get ready, you and your dorm-mates go down to the hall for the assembly. It's a large room and is completely packed with other students, staring with anticipation at the stage at the front. Soon the headmaster comes on stage.)
Headmaster: welcome back students, and for those just joining us, welcome! Here, I have devoted my life to making sure all the students in this room have a expressive knowledge in the four magic types. And this year, I have chosen to go all out on this. As such, I would like you to give a warm welcome to our new teaching staff! (He points to the side of the stage, where team Kirby walks out, followed by a roar of excitement from the students. Pink let's this go on for a bit before rasing their hand and calling for silence)
Pink: yes, thank you. Hello everyone! So, it was your headmaster's idea to have us as Teachers, so, I said "why not?" So, here we are! Ready to teach you all to the best of our abilities!
Headmaster: right. So, of course, I have to go through the rules for the new people. Besides having common sense, using any offensive magic on another student without a teacher's permission is strictly banned. Annndd that's about it really. If it seems it would get you in trouble, it probably is. Right. That's about it. You will receive your timetables on the table in the hall. They are separated by dorm. So your dorm-mates will be with your timetable.

(as they walk out of the assembly with the other students) Theo: (to the other 3) "So guys, where do we get our timetable?"

(Reply limit got hit so now this is gonna be Weird to navigate but oh well)

(It's a few hours later, everyone is asleep, except you, thinking about tomorrow. Suddenly, a loud crash sounds, waking coal up. It sounds like it came from the dorm window. Silently but quickly, coal goes through their things and brings out a few items. A slightly worn wizard hat, a wood staff with a blue orb in it, a helmet and a small sword. They look at them for a moment before handing the staff and hat to you, and putting the helmet on. You can hear a door open, presumably the other 2 leaving the room to check what happened.)

Theo: (following behind) what was that?

(coal shakes their head, then leaves the room with you. As you leave the room, citrus and grape are ok, but you noticed the window is broken. Citrus and grape turn to you and coal, in panic)
Citrus: wh-where did you get those fro-
(Coal grabs a hammer with an iron trim, a flask with a star on it, a helmet with small horns on it, and a cap with glasses. They give them to the group)
Coal: my parents bought them for me before I ldelfeft.
Citrus: and your giving them to me? Tha-
Grape: stop you all. The front door is still closed. Whatever has done this is still in the room. (They put on the cap and hold the flask.) We need to make sure whatever did this doesn't take anything from us.
Citrus: uhh, grape?
Grape: void damn it, what now?
Citrus: did we close the door to our room when we left?
Grape: of course.
Citrus: its open. (Actually shaking)
(Suddenly, a dark figure is visible in the doorway of citrus and grapes room. It pauses for a minute before, out of nowhere, a large orb of energy comes flying at the team. Coal quickly throws up their shield, deflecting the attack.)
Citrus: what the hell?!
(Coal attempts to take a swing at the figure, but gets blocked, then launched backwards. Barely missing the landing and ending up on their face. You notice as they move there's a small glint of blue-ish light in their hand, coming from some form of rock.)
Grape: Theo! Do something! We clearly can't hit it with melee, and I don't know how to use this thing yet! (They wave the flask around in desperation.)

(oops I screwed up coal's diolouge by mistake they are supposed to say "left" instead of whatever the hell I typed in place of it)

Theo: alright... focus... focus... (as he closes his eyes and outstreches his right hand, blue magical energy begins to appear around him, he opens his eyes as the energy forms into a blue ball of light in his hand that suddenly blasts forward and strikes the figure in it's centre) Take that!

*light blue light.

(a clock like sigil appears on the figure momentarily, with the single hand moving from 12 to 3 before dissolving. The figure seems to panic at this, and then charged straight through the team, sending them all flying, before leaving through the window. As it leaves, the front door opens, revealing four more kirbies, a pink, yellow, blue and green one, with golden and more powerful looking gear than your team's set.)

Pink: what on earth happened here? I heard the noises from across the corridor!
(Grape and coal get up, citrus struggles to however, because of the weight of his hammer. The green Kirby walks through the door, before helping citrus up. He smiles at citrus while the other dorm members look stunned.)
Green: don't worry man, you'll get used to the hammer's weight eventually!
Grape (panicking): well, we heard this noise, we came into the living room, and something attacked us before Theo scared it off with his attack.
Blue: was anything stolen?
Grape: no, no I don't think so?
Blue (to pink): something serious has happened here tonight. Every dorm was broken into, but this dorm is the only ones who where attacked.
Pink: well that was some serious bravery, actually standing up to it without a second thought! Whos gear is this?
Yellow (mumbling): I'd call it stupidity but oh well...
Coal (stuttering): i-i-its mine..?
Pink: good thinking. Sharing gear with your team to protect them.

Theo: (whispers to grape) uuuuhhh... who are these guys? They seem pretty strong.

grape (wispering): ill explain in a bit, coal looks like they are about to combust
blue: you may want to check your belongings. it seems weird to battle a bunch of students for no reason.
yellow: seriously though? taking down a completely unknown foe in one hit? that is incredible! theo, wasn't it? I cant wait to teach you!
(yellow is slapped by blue)
yellow: damnit, I just said something I shouldn't have, huh?
pink: yup. alright, we will let you recover now. better get going before yellow spills anything else. (they wink at the dorm members before closing the door.)

Theo: (reality sinks in) I did a spell... cool

Citrus: nice to meet ya, Theo!
Grape: alright, good to meet you. Anyways, you probably have some things you need to put away, right? Your room is the one on the right, your sharing with coal. Then, we sort out what to have for food tonight.

Theo: Alright thanks (goes to put his stuff away)

(after putting your stuff away, you discussed food options with the others. Ultimately pizza was decided. After it gets delivered, citrus starts up a conversation about tomorrow)
Citrus: did you know that we get our first set of gear handed to us?
Grape: we know, citrus, you've said this 4 times beforehand.
Citrus: well, I don't recall mentioning this, but there's rumours going round the campus right now about us getting a visit from team Kirby?
(The other two drop their pizza slices in shock)
Grape: wh-well they are only rumours, right? There's no way that one of the greatest teams of all time would show up to a school?
Citrus: fair enough, but apparently someone saw "TC - 11AM" on a clipboard one of the staff had.
Coal: could you imagine though!? (Everyone is shocked at coal speaking, let alone with this much fervour) Getting to see the saviours of the dream Kingdom, first hand?!
Citrus: damn coal, you... Really like team Kirby, huh?
Grape: anyways.... What is everyone planning on majoring in?

Theo: Oh uh... beam magic

(Sorry bout the stalling I had a test today)
Grape: well, I think I'll go for healing. It's such an important skill.
Citrus: well, I don't know about you, but swinging a massive hammer around sounds badass.
Grape: so that means coal wants the swords? (Coal nods, back to their normal quiet self) I knew it. I mean it's obvious. It's one type per person in a dorm.
Citrus: and that the leader of team Kirby also uses on- (gets smacked by coal) OW!

Theo: (turns to Coal) why'd you smack Citrus bro?

(coal shrugs)
Grape: I don't really care at this point. Coal does this every time citrus tries to wind them up. I think we should all probably get to bed now. Before coal knocks citrus out at least (they chuckle at this)

Theo: alright (heads over to his bedroom) night, guys.

Rules: no ERP, any non-joke oc can be used, but I will default to using Kirby's for the other characters if you don't specify you want me to use other species. I may be slow on replies, you can use any class you want.
