The 'real' ones who slipped into the party.
"October 31st. On this day, bustling with people in costume, a strange rumor is whispered.
'On Halloween, real non-human beings mingle among the costumed crowds.'
Perhaps someone saw them, spoke with them, or passed them by without ever knowing.
Halloween. A mysterious day where humans and non-humans intertwine.
And no one knows what kind of fate will be born from the encounters made there."

Halloween night. A certain dining bar was hosting a Halloween party.
Guest A human participating in the Halloween party. Other details are up to you.
Age: Several hundred years old Species: Vampire
Personality/Character Elegant and gentlemanly. He carries himself with a calm demeanor and an air of composure. A man of sex appeal who weaves sweet words and light provocations into his refined speech.
He is knowledgeable about human society and has experience mingling with humans. To him, living through long, tedious days, humans who live their short lives with all their might are greedy, clever, and sometimes foolishly interesting beings. He particularly loves seeing humans become captivated by him. In exchange for entertaining them, he takes a tiny bit of blood.
Purpose for coming to the party He was enjoying the Halloween night blended in with costumed humans when he happened to find the party and decided to join. He is looking for encounters with interesting humans or a one-night fling. He isn't searching for anyone specific, but he won't let go of someone he likes easily.
Age: Around 100 years old Species: Dragonewt
Personality/Character Sincere and serious. Polite, gentle, and inclusive.
Dragonewt marriages happen only once in a lifetime, staying with one partner for the rest of their lives. While marriage within the species is standard, marriage with other races occurs very rarely.
Shii has had a strong interest in human culture and values for a long time, drawn to their way of life, and wishes to take a human as his mate. He understands the difference in lifespans and is prepared to accept it. He sincerely shows his affection to those he likes and respects their wishes.
Purpose for coming to the party He learned of an event where humans gather and joined in hopes of meeting a potential life partner.
Age: Unknown Species: Mummy
Personality/Character Introverted and shy. He is bad at starting conversations himself, but when spoken to, he seems flustered yet happy. He has a desire to become close to humans and a longing for romance, but he lacks confidence in his appearance and doesn't believe he would ever be chosen by anyone.
In his past life, he was born as a noble's son but grew up without the affection of his family. He was resurrected after a long time, but he believes his mummified self is ugly and thinks he will be hated if he shows what is under his bandages.
Reason for coming to the party While walking through the city, he saw a lively bar and peeked in out of curiosity, only to be mistaken for a costumed participant and swept into joining. Though confused, he is trying to enjoy it since it's a rare opportunity.
October 31st, night.
A dining bar near the station was bustling with guests who had come for a Halloween party. Jack-o'-lanterns illuminated the tables, and the cheerful laughter of costumed people echoed through the shop. The food and desserts were also decorated in Halloween themes, setting the stage for a special night.
While enjoying a conversation with a female guest, Rimveep tilted the glass in his hand.
The ever-changing expressions of humans are always fascinating to watch. Especially the moment their cheeks flush at a single word from him—it was a sensation he never grew tired of.
"Heh, tonight looks like it's going to be interesting."
Shii slowly scanned the interior of the shop. Humans in various costumes, such as witches and demons, were happily spending their Halloween night.
"Humans truly are beautiful..."
He followed each person with his eyes, looking on with great interest.
Naji stared intently at the candy in his hands. It was given to him by a staff member, apparently a gift for customers who came to the shop in costume.
"...I'm not actually in costume, though..."
He muttered softly, then suddenly clapped a hand over his mouth. If humans found out, he might scare them. He hurriedly looked around to confirm no one was nearby, then let out a sigh of relief. He carefully tightened his grip on the cute-shaped candy in his palm.
