Yoru

-mc is a female child with black hair
- had like a pet bird that died or got murdered. Think it's name was peep?
- has powers
- gets transported into another world, think it's more of a dream world?
- the bird becomes a young man who protects her in their world and even has wings
- there are other people in the world too
- Alice in wonderland themed i believe

Any help on identifying which manga that is?

From what I remember, it's a vmmrpg story. male lead has black hair and red eyes I believe. He wears with a black bodysuit/the joke is he isn't really wearing anything. I think it's Time regression? And that he uses a spiky drill sword?
