You woke up in "your" bedroom in the 80s. 

Sefina woke up one day in the ruins of a temple. While exploring the said temple, she found a sword and decided to get it. Slowly, she found out that she has been isekai'd and thus she has been teleported into a different world. She began to leave the temple and went into the forest to start leveling up.

Look! A level 1 monster. How pathetic.

I am Shandy. Secretly, I also go by the name Fei to those who are very close to me. My eyes are amber colored. My hair is purple with a blue highlights on one side. I get bored so easily that I went job hopping just because of boredom. Sometimes, I can be asocial. I'm also not a fan of bothersome work. I like fun but I don't like too much work. But when I feel like it, I can be a bit playful sometimes. Just to keep things interesting. Although, I don't like men who are liars and cheats.

A delinquent school girl.

It's 1992. You are an intern at Radio X. Your supervisor, a radio DJ named Sage—if that's her actual name. The goth DJ has an edgy personality matched with an acerbic mouth ready to spout rude remarks if she finds something that irritates her. 

Sage is worryingly thin and quite unhygienic. She doesn't like wearing underwear but doesn't wear anything revealing. She loves long plaid skirts. She has multiple tattoos on her body. The one noticeable is a Celtic tattoo on her arm.
