I didn't think I would need a prologue but I decided to do it anyway. You don't have to read it but it does get brought up in a later chapter.
A ravenette girl in her teens held a blue Nintendo 3DS XL in her hands. White earbuds were in both of her ears on one (or two) end(s) and connected to the lower left corner of the console. She kept an intense gaze on the screen in front of her and a firm grasp on the 3DS. In a matter of minutes, a GAME OVER in blue text appeared on the black screen. She took a deep breath and repeatedly pressed the B-button, closed the software, and shut down the console. She picked up a bottle of water and chugged some of the water before putting it back down.
On the desk, a light next to the top speaker of a white smartphone blinked in green. The teen turned on the phone and checked to see what it was.
You're still up? A message read.
She picked up the smartphone and typed back: Yes
Seconds later, another reply came: Go to sleep. It's almost midnight. Did you finish your homework?
The ravenette smiled and typed a Yes
I won't sleep unless you sleep first. You remember our plans tomorrow some time after school, right?
Yes
Okay. Goodnight.
Goodnight The teen shut down the phone, turned off the lights, and got into bed.
Nearby, a blond boy looked out the window of his room. He watched the window next door despite the beige blinds obscuring everything inside. The room's light went dim. The blond then walked away from the window and turned off his phone, his room's lights, and got into bed too.
A blond boy in blue sleepwear and slippers walked through a wide empty hall. He held a small handheld flashlight pointing forward and on the floor showing a red carpet floor among the darkness in the room. Up ahead, he noticed someone coming his way. He lifted his flashlight forward revealing a girl with black hair and eyes, a black suit, an arm cannon, and brown leather shoes.
"Oh." The blond greeted her until he noticed some dirt on her clothing and hair.. "H- What are you doing up so late? It's almost midnight and it's dangerous to go outside at this time. Where were you?"
"Sorry, I got occupied after dinner and time flew by. I'll go to bed once I get back to my room."
"Don't forget to take a bath before you do. You have another day to prepare for. Tomorrow's Friday. We can't have you fight when you're not at your best state."
"I know."
"Do you want me to guide you back? I was on the way from a bathroom break and we're neighbors."
"Alright." The ravenette took the blond's hand and they started walking.
"What were you doing anyway?" The blond asked.
"I just left the mansion for a while." His companion responded. "And then…" She started to ponder. "What was it..?"
Seconds passed. "You don't remember?" The blond broke the silence.
"I guess so. It must have slipped. But it doesn't really explain all the dirt on me. I must have got into a fight so bad I completely forgot what it was." She looked up ahead. "Oh, we're almost there. Anyway, goodnight."
"Goodnight," The blond said before his companion went into her room. He paused before saying another word, "Hinata..."
"What could possibly go wrong?" The protagonist said.
Elsewhere, a person with a wide grin lifted their hands from a keyboard.
"Everything." The person said.
If you read the prologue, congratulations I guess. You got a free insignificant detail.
