A Big Shot Becomes a Minor Character [Quick Transmigration]

This is the prequel. The sequel is titled The Supporting Male Character Doesn't Follow His Character Setting.

I didn't handle the first world very well, so I recommend starting from the second world. Mwah.

My name is 0009, and I'm a newly hired System. The higher-ups assigned me a Host who was supposedly very hard to manage. The veterans told me this Host used to do villain missions! He could lead good people astray, make black sound white, and steal all the spotlight from the protagonist without even apologizing!

A person as evil as a demon must be a monster with three heads and six arms, right?

I gritted my teeth and went!

“H-Host!”

I finally met my “three-headed, six-armed” demon Host: a little naturally curly hair, a tall... um, slender build?? Foxlike eyes, dimples, and maybe he'd just hidden his three heads and six arms. He didn't look so scary after all!

The Host's first words were sharp. “Huh? The higher-ups actually assigned me a System? I've been here for a whole month. Why are you only showing up today?”

Oh no, what was I supposed to say? All I could do was introduce myself to ease the awkwardness!

“0009 isn't a nice name. How about Song Bao? I'm Song Yuan, so you can be Song Bao. It's a perfect match.”

Me: “...”

And that's how I got renamed. But Song Bao... a coward??!!

Waaaah, this Host really is a wicked demon!

Second-version blurb: The System trembles in fear after suddenly being saddled with a max-level troublemaker.

Troublemaker: Playing a cannon fodder role is easy. I'm good at it.

System: After being reborn, the male lead wants to become the top student at No. 1 High School. He'll have to face-slap the cannon fodder.

Troublemaker: Then I'll be a good-for-nothing. I'll sleep in class, play games after school, and leave my test papers blank to make the male lead look good. (Then I'll get a perfect score and become a top scholar just to make him furious.)

System: After transmigrating, the male lead wants to become the strongest person in the cultivation world and have a harem of three thousand!

Troublemaker: I'll be his sidekick! (I'll beat him at every turn, then get bored and ascend, leaving him in second place for ten thousand years.)

System: Looks like you really know how to play along!

Troublemaker: ) Hehe

Theme: Harmony and friendship, building a better society together
