My Species Is Nearly Extinct, So I Changed Sex

Important: The heroine changes from female to male. All male leads are alien species capable of taking human form.

In one species, when a male dies in a crisis, a female in the group changes into a male to take his place and protect their territory.

Chu Ran thought that was something that happened only in the animal kingdom.

Until one day, it happened to her. Her sex changed.

It turned out she wasn't human.

She became male, but the original male hadn't died. Now weakened and covered in wounds, he stubbornly refused to become female.

So what if you turn female? What's the point of being so stubborn? You even insist on fighting me.

In the end, she actually beat him. So which of us gets to be the male now?

Theme: Protect the diversity of rare species.
