Help me find back this anime movie pls?

Okay so about 7-9 years ago I watched an anime as a child. However after that I lost the anime and never found it again. It's been so long that I'm genuinly thinking I just made everything up lmao. But a few months ago I found back another anime I also couldn't find back for YEARS, so I'm still having hope haha. Here is all I can remember from it:

- The anime was about 2 brothers. I believe their parents got killed or smt in the beginning. They both had black hair and were pretty young (Like 6 and 16 years old or smt, could be different though).

- The oldest brother started taking care of the younger brother and his name might've been Yuu or Yu. I don't know why but for a long time I thought that the name of the movie was just "yuu" and "yu", but I can never find anything on that name so it might not be called like that.

- It's a movie

- It's an Isekai anime. There is like a portal the brothers sometimes go through and then they teleport to the same world, but like a parallel. Example: The color of the sky changes. There also are ghosts in that world. It was like a huge portal in the middle of the city and not a lot of people knew about it. It was around a staircase I believe.

- The oldest brother wants to go to that other world and gets like a ghost friend (?). I don't know there was some kind of spirit following him.

- In the end they both went to that world and the younger brother got possessed by one of the spirits and stabbed his older brother. I believe he died, but I wasn't sure at the time.

Please help me find it lmao. I also have another anime like this that I can't find, but I will leave that one for now :)
