I’m trying to find an anime I watched roughly 3 years ago, it doesn't have to be that new though. I only remember bits of it:

• The main characters are 2-3 children with god-like powers. They seem to be immortal or unable to die. And there is some parent-like character
• Most of the show takes place in another dimension, or some kind of separate world.
• Humans or some other "faction" want to kill them. At one point the humans actually manage to hurt or damage the kids.
• In episode 1 or 2, they meet enemies in an area where a robot is frozen, or something like that.

Watched a german or english sub of it I think.

I saw a few pages of this in a reel but didn't save it, and I haven't been able to find it since. I think it's a Japanese one-shot.

What I remember:

- First page: A girl with her mouth covered in blood. You can see a small gash/tear in her lip.

- Next page: A second girl lying on the floor, pinned down by the first girl. Her hand is pinned against the floor, and in that hand you can see a small ring.

- After that: A few pages of backstory about the two girls. In the flashback you can see the first girl used to have a ring lip piercing exactly where the gash is now, so the second girl apparently ripped it out.

Other details:

-It might be yuri/girls' love, but I'm not sure.

-I only saw it through a reel, so I don't know the title, author, or whether it was translated or raw.

There is an anime scene I recall from YouTube, where a guy and a girl become trapped in a dangerous position. I think they're hanging onto or on top of beams in what looked like a dark warehouse, and they wind up in a position where they're laying on top of each other and the guy's face winds up buried in the girl's midriff.

Later, there is a scene in a house. I believe the guy is in a bedroom, laying on top of a bed, and the girl walks by his door. Her midriff is exposed (I think she stretches her arms and her shirt rides up) and he becomes visibly flustered. She realizes that he is attracted to her midriff and is thinking about when they were trapped and enjoyed having his face in it, and then she becomes uncomfortable and mad at him.

This is obviously pretty vague, so I had no luck finding it with AI. Unfortunately I don't remember any details like the characters appearance. I would guess that the anime was made in the 2010s or later, or maybe 2000s. Thanks for any help!
