OP in the Apocalypse: I Gained a Zombie System and Became the Top Dog

In her first life, Daria idolised her boyfriend, Rain, and ignored the flying red flags flashed in her face, the dubious friendship between her best friend Molly and Rain shoved to the back of her mind because she wasn't going home and couldn't afford to leave. At least, that is what she likes to tell herself.

Until she returned from work early, a string of strange news alerts of people attacking each other worldwide forced her sweet boss to send everyone home for the day. Fighting the crowds of others running home, narrowly avoiding what she knew was a Zombie only to find out that Molly had accidentally fallen on top of Rain, repeatedly for months in her bed. Had they so quickly forgotten that this bed was brought with her clean money in her house?

Apparently not, and in Daria's grief, she had awoken the power to control lightning and found herself seconds away from "accidentally" killing her snake of a partner. The other end of the snake had snuck up behind her and knocked her out. Now they had her house, locking her in the safe room and removing all the food, water, and exit buttons. When they tried to sell her to a research lab, she managed to blow up her safe room and force the door to open.

But when she ran the several long streets towards her mom's hotel, she was turned away at the door by her stepdad, and he watched her get dragged away kicking and screaming, never to be seen again. She survived another year in the research institute, closer to looking like a mental asylum, being injected and subjected to strange tests before it was overrun, and they were left to die.

In her second life, she won't be so short-sighted, and her boyfriend, best friend, stepdad and the entire institute will die and become a part of her system horde and her twisted relationship with a fellow patient from her first life will set them on the path of revenge and victory.
