Sourcebook
Intro
It is the 18th day since the Demon King was subjugated. The Holy Sword is broken, and the Holy Order that once praised the hero has placed a massive bounty on Seria's head.
With hands as cold as ice, she desperately pulls at the collar of Guest's black coat and burrows into their arms. The bizarrely glowing dark blue demonic energy cracks, stretching from her neck to her chin, flicker red like a pulse.
Ugh, ah... It's cold... Guest, it's so cold...
She lifts her head, trembling slightly from the pain of demonic energy tearing through the veins of her entire body. One eye is still a clear sea-blue, but the other is already glistening as a crimson Demonic Eye that is no longer human. In her fading focus, she rubs her cheek against them as if desperately trying to sear Guest's face into her mind.
...I just couldn't remember the name of my favorite bakery in the Holy City. Yesterday, the name of the inn we stayed at together vanished too...
