Athletes Versus the Infinite Flow

*Finals are over. I'll keep to a regular update schedule from here on out.

Blurb:

Mickey is a well-rounded teenager, an ordinary high school graduate. One day, she went downstairs to buy breakfast. As she stumbled around half-asleep, the air suddenly turned bitterly cold. When she looked up again, the whole world had fallen into madness, and she was fighting to survive in a game called the "Inner Space."

A sinister middle school, a hospital covered in warnings to run, an orphanage that buried the dead... Everyone struggled between the rules and death, and assumed she would have a mental breakdown. But...

[Your teammate has been possessed by something sinister?]

Mickey hit the entity and her teammate with a left and right hook, leaving them both seriously injured.

[A weeping ghost in the mirror, tears of blood streaming down her face?]

Mickey reached into the mirror and broke the ghost in half with a hip throw.

[The boss secretly changed the escape rules?]

Mickey thought for a moment, then switched from a knee strike to an elbow strike in front of the trembling boss. The boss lost consciousness.

Everyone was stunned. "Didn't you say you were an ordinary high school student?!"

Mickey scratched her head and smiled shyly. "But I'm also a Muay Thai boxer and the center on my high school's rugby team."

Everyone cried foul as Mickey's powerful roundhouse kick, like a gust of wind, snapped the neck of the sinister creature trying to ambush them. For a moment, they couldn't tell which side was more of a threat to their sanity.

Even more frightening, Mickey was unstoppable in the Inner Space. With her awakened talent, [Tyrant], she climbed to the very top and became the true ruler of the rules.

While everyone feared her, stayed on guard around her, and walked on eggshells, one person who had been by her side from the very beginning stayed with her gently.

"...They've all left. Why are you still here?"

The person smiled gently, still as timid and unassuming as ever, hiding his feelings behind his earnest words. "We're teammates."

Infinite-stream devoted, timid office worker X athletic, adorably clueless female athlete

Notes:

The male lead is never going to become a tough guy.

The female lead is incredibly tough! A 182-centimeter muscular wolf queen.
