Those Years I Was Caught in the Demon Slayer Corps' Love Triangle

Returning after a hiatus, updating slowly, and working hard to finish Unless otherwise specified, edits are just typo fixes, so there's no need to reread ^ε^ [You must learn the wish of your target, Tomioka ■■, and help him fulfill it.] This mission was simple. 000 thought even A Zhi, a new Host, could complete it, so A Zhi started diligently working through the mission. Progress at the Tokitokiya was too slow. The two of them decided they had to move elsewhere to continue the mission, but then strange things began to happen. That centuries-old portrait showed a woman who looked almost exactly like her. (From the artist: ■■ Yoriichi) At night, strange noises came from the roof, along with a pair of eyes watching from the darkness. (From the gourmet: Daki) A fake Western-suited man, who was really the demon king, suddenly appeared in the crowded street and stared at her as if he'd seen a ghost. (From the scumbag king: Muzan) This place was too dangerous. A Zhi decided to find somewhere safer to do the mission. The night she made her escape was dark and windy. A Zhi didn't find the person she expected to come for her. Instead, a strange, towering figure stood with his back to the moonlight. He was a demon with six eyes, dressed in the dignified robes of a samurai and radiating an intimidating, icy presence. But... did this demon know her? [Warnings] 1. I love melodrama, so consider this a warning. 2. Unless something unexpected happens, characters may be OOC, but I'll try to keep them in character. 3. Logic serves the plot, and the characters' intelligence serves the plot too. 4. The female lead is a silly beauty and may not become stronger. Please think twice before reading if you dislike that. 5. My writing isn't great, about elementary-school level. If you don't like it, run! 6. The pairing hasn't been decided yet. We'll see how things develop; it may be decided in an extra chapter. 7. There is an anti-theft setting, currently at 60%. This may be adjusted later. 8. The blurb was finalized on 2022.2.10 and has been screenshotted. Theme: Break free from darkness and embrace the light
