Why is everyone hating on the sister? I reread ch 1 and she kicked mc and he transmigrated but I don't think a kick can kill you. It was probably the restart button and/or getting knocked out.
Plus it seems comedic exxageration.
Don't hate her so fast. Having a sister can be comforting

You should probably read up on how Houdini died. A kid walked up to him and punched him four to five times in the gut when he wasn't expecting it. The punches ruptured his appendix, and did a whole other mess of nasty. So yes. A kick to the gut CAN kill you. Especially one that is forceful enough to launch you across the room when you don't have any head protection!
If someone reads the grandpa thirst comments they'll be so concerned lmfaoo
