After being "retired", the young and upright officer, who was like a saint, actually lived alone in a ghost house in the woods far away from people. "Alone"? But before his eyes, he saw a demon with the same face and completely different aura appearing next to him, and shamelessly tempting him - "Who are you?!" "I don't mind if you call me late night... Although I hate late night the most." That man like a saint - "Help me... "... Save? I should..." (Who wants to harm you? In front of you is the devil who keeps saying he hates you, but his eyes are the same as yours...) Intertwined with purity and evil... *I deeply feel that my IQ will be seen through before I write it* The sentinel/guide setting is mixed with personal devices. *I didn't think about Guren's spiritual animal. *Inspired by Ayatsuji Yukito's "The Doll House Incident". *...
