Queen of Card legacy: All my cards are Mythic!

Female protagonist- no yuri- lesser/no romantic connections- WPC Oct-

After the great protection array ran out, aliens invaded Earth in 3000. Cosmic power projected in the form of cards. Everything in the world mutated, putting humans on the verge of genocide until that happened.

We can awaken these cards and become card masters who can use the abilities of these cards!

The war ended in 3450, with the last alien being wiped out from the world. Earth expanded, filling the entire solar system.

Luna Lancaster, the third princess of the Lancaster kingdom, undergoes an awakening ceremony at age eighteen , only to be judged as useless because of her awakening of a common-ranked card.

She was expelled to a city in the extreme north, where criminals and outcasts ruled. On the way there, she was killed by monsters—that was what everyone thought.

However, something no one expected happened...

Benjamin Evin, a terrorist in the past on Earth, reincarnated into the body of Luna Lancaster, an outcasted princess. With him came the mythic card,

“Realm Blaster.”
