I need helppp T~T

Okay I don't remember much, but I think it's an adventure manhwa (colored) , and there's stages of a game? Where you need to protect your world from an otherworldly invasion . And similarly, you get sent to another world to destroy it where you ironically become the invaders of that other world. And it's a sad cycle, where you're both protecting your world and destroying the other . And each time the invasions get more powerful. Okay I think that's about it for the plot that I remember .

Now for details, I think the other world invasion team had a redhead, a blue haired lady that uses gems and jewels to make things for her attacks? And there's a black haired lady too. Oh and there was a small girl that was locked up in some other world prison? For a long time, until she was rescued by the opposing team. I think T~T . And the both teams met each other during an island game? And kinda became friends and layer got to know that they were enemies.

Oh also I don't know if it's part of the same story, but this is also something I remember- so it's a tiny world. And the big people are supposed to destroy the small people. And if the bug people refuse to destroy the small people land, they get negatively affected by the system and the bug people become small too. And there's a Japanese team there that meets a Korean team? I'm sorry I'm very confused. I can only vividly remember random details and images .

Please help me find this if anyone knows . Thank you very much. Also I'm sorry for this longgg essay T~T
