Please help me find this mangas name

[Soveregin]

It started out as some game world where this family is some powerful figure within the game and lives peacefully within a small house. A bit into the manga we find out that the real life counterparts of this family are actually completely dysfunctional and use the game to escape reality, not knowing that they know, and are on good terms with each other in the game. later in the manga something happens to do with the dad being some scientist or something, but something about his past means that elements of the game become integrated with reality and people go missing when these weird towering figures send them into eternal torture "testing their human limits."
That's pretty much about all I can remember about it, there's also the common phrase of the words "hello world" throughout the manga. The ending was the main character buying a house replicating their in game house.
I've been searching for hours but I couldn't find anything, if someone knows the name then please tell me.
