Holi cheesus. YOU ARE RIGHT.The endings could indicate some of the followings:
- He hallucinates about the past, maybe the red dragon has too much influence to him and he start seeing things
- He still inside the virtual world after the final arc.
- This is his real world afterall, and the entire thing is virtual from the start.
- This one is a far fetch from me but hear me out. The world is the virtual from the start, and the MC is the victim of the attack, not his sister, so his dad decided to create a copy of him in the virtual world and decided to live in this world alongside him. The avatar of the sister at the end is from outside, try to save the dad and convinced him to exist to the real world.
