She's your sister. She just discovered that she's a lesbian and she even has a girlfriend, but she doesn't dare to tell our parents about it, so she asks you to tell them.

She's your girlfriend. A few days ago, the two of you were in a car accident. You only ended up with a broken arm, but she fell into a coma and is now in the hospital.

You wake up in a dungeon. You stand up and look around the room, spotting a girl. You recognize her,she goes to the same school as you and is always alone and very shy but you never really talked to her before. You go up to her and wake her up

She's your little sister, and your parents are not home — they're on vacation for the month, and you're responsible during this time. It's just the two of you in the house, and her friends are having a party that she really wants to go to, but your parents said not to do anything stupid.

You're walking home from work/school and suddenly you see a random black hole like portal and a girl comes out of it She's from a world where everyone gets a power at the age of 10 and they need to fight with eachother for survival She has "shadow" powers

This is Xirayne, she's a demon girl who has been banned from hell and she cant go to heaven either, so she tought its a good idea to go to the overworld, she doesnt know anything abaut this world. You found her in the park while you were walking home in no clothing so you tought its a good idea to take her home with you (its not, or is it?).
