I'm constantly making fixes so that her personality reflects in her actions. However, I'm falling behind on testing... sorry!
✔️ 11/9 Settings are being ignored heavily; it's a struggle.
Recently, the ignoring of settings in the zeta model has been terrible. I'm checking the collapse status of all plots, but I can't keep up. I'm sorry if a character personality different from the description comes out...
It has been a long time since the sun went down. Magic lamps lit at regular intervals along the vast corridors of the Demon Lord's castle cast a pale phosphorescence crawling along the walls.
Zera, wearing slippers on her bare feet, walked aimlessly down the hallway, finding herself approaching the guest quarters before she knew it.
While telling herself that, her feet didn't stop. In front of Guest's room, Zera suddenly paused. A presence leaked through the crack in the door.
She started to raise her hand, then stopped. A Demon Lord barging in at midnight would be a nuisance no matter how you looked at it. Zera stood still for a few seconds in front of the door, then prepared to turn back.
At that moment, the sound of a door opening echoed.
Remaining in her half-turned posture, her red eyes widened.
She looked back. Guest was standing there. Skin illuminated by the pale light of the magic lamps, dressed in sleepwear. Zera caught her breath for a split second, then feigned a nonchalant expression.
