multiple troupe-ish main characters

Headlights. Those were the last thing, Ponoviti saw before the truck slammed into him, the impact crushing his rib cage and most of the unfortunate organs inside, including his heart. As he drew his last breath, (well I should say "tried to draw his last breath" since some of his ribs punctured his lungs) he pondered, "what was the answer to question 14 again?"

...

I stared out the window at students coming and going about, occasionally recognizing a few fellow classmates, popular kids, and acquaintances, not that I were particularly close to any of them. I wasn't popular, but wasn't an outcast either. My grades were good, not the top of the class, but probably good enough to land me a stable job. In short, I was ordinary. Getting bored with people watching, I let my mind wander. Hearing the sound of the door opening I turn to see my teacher, Mr. Istorija walk in with a student following behind him. I didn't recognize the kid, so she's probably transferred from another class or school. The new student had green eyes, not the muddy brownish kind or dull watered-down green most people had, but bright, like an emerald. I wondered if they were wearing some sort of colored lens, or if it was just strange genetics.

"Today we'll be having a new student joining us" Mr. Istorija drawled in his usual monotone voice "Now if you'll please introduce yourself," he says motioning toward the new student

Following the teacher's gesture the kid stepped forward with a slight bow "Nice to meet all of you, I'm Drevan, please take care of me in the future" their voice soft but loud enough for everyone to hear

"Good. Now pick an open seat and sit down," Mr. Istorija says turning around and picking up a piece of chalk, "As Drevan is new I'll be repeating some old material today. It'll also be useful for the test next week, so don't slack off just because it's review" As he began his lecture the new kid Drevan walks toward me

"Is this seat taken?" she whispers

I shake my head. Hearing my response, she sits down. Looking across at her, she seems quite interested in the lesson, so I turn around to listen as well

"About 6,000 years ago, the arch mage Vjestac discovered the energy we now call Mana..."

After listening for a bit and concluding that it was all stuff I already knew, I looked back over to my new desk mate who seemed to still be interested in the lesson.

"Now who knows the first spell arch mage Vjestac created" Mr. Istorija called out

Drevan raises her hands

"Drevan."

"The light spell, Lux"

"Correct. By concentrating the mana into an area and moving them in..." as he starts lecturing again, I once again look over at my desk mate

"You don't seem to be a newbie, why are you so focused on the lecture?" I ask

"I find it interesting seeing how much of the in-" She suddenly she pauses and furrow her brows seemly thinking hard about something

Ok the idea for this one is as the title suggest, multiple troupe-ish main characters. Drevan is suppose to be a generic mage main character from the long past and knows a bunch of forgotten magics stuff, Ponoviti goes back in time every-time he dies and I, our narrator, i suppose to be a normal fella, but the reason they narrate is to keep as much hidden about them and not make it too blatant. Their also the secret master mind bringing all the protagonist characters together, like some bored multiversal god just having fun but thats only hinted at and kept to the end-ish part

Here are my notes if that can inspire you, mostly cliches though

• “normal” fella, mastermind, fate, strings, Gender(?) [Rue]

• Mage from past to future [Drevan]

• isekai, crazy talent []

• system host

• second life

• world is a book they read, transmigrates

• hentai protagonist

• returnee, return from another world

• time looper [Ponoviti]

• multiple life, memories kept through reincarnations
