Arte was a legendary assassin in Arcadia.

After being summoned to modern-day Earth as a Boss Monster, she learns that the Hero Party she once knew supposedly died a thousand years ago.

Then she meets Baek Siwoo, the current Hero.

Naturally, Arte assumes he's either a fake or some kind of puppet.

As she follows Siwoo and searches for the truth about her former comrades, Arte finds herself wandering around modern Seoul with her shadow wolf, causing one misunderstanding after another.

She came prepared to unleash a thousand years of pent-up rage.

...Actually, maybe she'll just live quietly instead.
