Boxing against the main character as a nobody

You've never really stood out in school all your life; the same close friends hang out with you, and the same average lunch is consumed almost daily, and once you've reached college, your motivations for changing that fact skyrocket.

Your background character energy that you currently have is unacceptable; you wiggle your way into the boxing club. Once again you mesh with the handful of other women also training there, but you don't let that shake you off. Despite the average build, you manage to get a bit lean in your abs and build very small muscles. Time passes as you have your scheduled debut match occurring in a boxing tournament! During that time you spend a normal time training, a feminine figure passes you, as it's a slightly above-average gal with a short bob cut~ish black hair; other boxers whisper around you as words like "Whoa, it's her" and "Isn't that the Aoi girl who won multiple local championships?" She had an aura around her that radiated something nasty... her uninterested face didn't help as she exhaled. She sensed the whole world revolved around her. Like you were just a small stepping stone for someone else, that thought alone brought shivers down your spine. Luckily you're not going to go against her. Totally.

It's the big day. You arrive at the venue, as you're the first matchup. Changing into your generic-ah boxing outfit, you walk into the ring and hear the crowd yell. You see your opponent; she's average. The nervousness crawls up your spine as you shake it off just like anyone else would. After a bundle full of hooks, snapped heads, and exchanges that weren't equal, you managed to win via count. The rush of joy came to your brain as you jumped in the air before regretting it right away. This wasn't an easy fight; you knocked her to the ground, and she managed to knock you back first onto the ring floor, but the outcome is all that matters. As you escape into the backrooms, you realize quickly this was a tournament. You had no clue, but this was a special occasion, so fighters were encouraged to stay after their matches and participate in the tournament. The rules were simple but unique: 7 rounds that are 4 minutes long, loss by KO or by count, and illegal moves such as elbows and knees are allowed but very much discouraged. The digital tournament bracket showcased the semifinal matchups; you lean in close as..... Futaba Aoi was matched up against you.

Your butt meets with a chair as you pat yourself down with a towel against your left side of your stomach; the girl who seemed to be the center of attention was against you. Instead of resentment, your thoughts go towards showing the world you aren't a loser destined to be a building block for other people. Even with average motivations, you can beat anyone you face. Time passes as Aoi wins her match with ease; it's now your match against her.

The crowd cheers as you're the first to walk into the ring. The announcer quickly leads into Aoi's entrance; it's actually happening. Aoi ducks under the ropes as she walks towards the center of the ring with little introduction. She still acts like someone her age; you examine her body, as she still has a couple stretches and a small bruise on her abs. Compared to you with a couple of bruises to the face and ribs, you seem to be equal.... Aoi sticks out her gloves, a common way to start a match; with that, you tap your gloves against hers. It was firm; the gesture was a sign of what's to come as the bell rings and the match has started. This was it.
