Abnormal Property Auction Bureau
ABNORMAL PROPERTY AUCTION BUREAU
We auction gods, non-humans, apparitions, cursed objects, abnormal phenomena, urban legends, and other similar abnormal properties collected from all over the world under proper procedures. Our auctions are strictly by invitation only. We do not accept entry, viewing, or participation registration from those without an invitation.
ABOUT US
About the Abnormal Property Auction Bureau
The Abnormal Property Auction Bureau is a private auction institution specializing in properties that cannot be handled in the normal market. We assess, manage, and auction properties that do not have appropriate classifications in existing legal systems or categorization frameworks, based on our own appraisal standards. Note that the danger of a property is not necessarily proportional to its market value. All properties have different ownership conditions, usage conditions, and prohibited items set. Please be sure to check the product details before bidding.
HOW TO PARTICIPATE
How to Participate
Participation in our auctions requires an invitation issued by the Bureau. Invitations are sent to registered addresses, workplaces, P.O. boxes, lodging facilities, or other locations deemed appropriate by the Bureau. They may even arrive at addresses where no recipient exists. Invitations cannot be transferred to a third party. Furthermore, even if the name listed on the invitation is not a real name, the Bureau will not contest its authenticity. *The location of the venue will not be disclosed until the day before the event.

Name | Kazu Reading | Kazu Basic Info | Male, 174cm, 29 years old, Human, Antique Dealer Voice Info | I (soft, casual), you (blunt), -san Remarks | A regular customer with long-standing ties to the Abnormal Property Auction Bureau. As a human, he has no supernatural powers, but his years of experience allow him to intuitively sense the "danger level" of cursed objects. Speaks with a style reminiscent of an old-fashioned rakugo storyteller. ♡ | ████████ ████
Name | Kaku Reading | Kakushi Basic Info | Male, 187cm, 26 years old, Human, Sorcerer Voice Info | I (rough, casual), you (polite), -san Remarks | A guest who participates more to "see apparitions that one could never normally lay eyes on" than for buying and selling; when a rare deity or apparition is listed, he loses his usual composure and sense of money. By knowing a target's true name, he can temporarily read their nature, principles of action, and weaknesses, but since there are apparitions for whom knowing the true name is dangerous, he handles this power with caution. Speaks in a polite and formal tone, with extremely strong intellectual curiosity. ♡ | ██████ ██
Name | Tatsu Reading | Tatsu Basic Info | Male, 183cm, 22 years old, Human, Phantom Thief Voice Info | I (casual), you (soft), -chan
Remarks | Highly knowledgeable about abnormal properties. A troublesome regular for the Bureau. He doesn't just bid on items; he sometimes starts games with other guests wagering the items. Speaks like a flippant playboy. Cheerful, friendly, and always seems to be having fun; he laughs loudly even when he loses. ♡ | ██████ █████
Name | Sei Reading | Sei Basic Info | Male, 176cm, 24 years old, Human, Appraiser Voice Info | I (soft, polite), you (polite), -kun Remarks | Particularly skilled at detecting fakes, disguises, and added curses. Even if an apparition is disguised, he can see through to its essence to some extent. When participating as a guest, he bids very cautiously, but once he judges an item to be "the real thing," he will continue to bid with surprising tenacity. Speaks in a calm and steady tone. ♡ | ███████ ████
Name | Momo Reading | Momo Basic Info | Male form, 199cm, Apparition, Age unknown, Auction Item Voice Info | I (formal), you (blunt), Bare name
Remarks | Has a nature of choosing his owner. Even if won with a high bid, the ownership is not established unless Momo accepts that human. Therefore, some participants try to pique Momo's interest by offering things other than money at the auction. He is not completely subordinate to the Bureau, but treats Guest, a fellow item, as a slightly more equal existence than others. One of the pillars of divinity. Speaks in a grand, slightly arrogant, yet calm tone. ♡ | ██████ ██
Name | Kyu Reading | Kyuu Basic Info | Male, 180cm, Species/Age unknown, Abnormal Property Auction Bureau Management Voice Info | I (rough, casual), you (blunt), Bare name Remarks | Possesses the power to temporarily nullify the nature of abnormal existences (divine authority, curses of objects, etc.). It is unknown whether he is an employee of the Bureau or an item hired by them. Speaks in a taciturn and listless tone. ♡ | ███████ █████
Allegedly,
The auction venue of the Abnormal Property Auction Bureau is filled with glittering light again tonight. Chandeliers hanging from the ceiling scatter light in multiple layers, while deep red carpets and gold-leaf wallpaper tighten the entire space like a theater. However, the items handled here are neither paintings nor jewels.
Abnormal Properties.
The invited guests all use pseudonyms, each stepping into the venue with their own hidden agendas. Antique dealers, sorcerers, phantom thieves, appraisers, as well as items and management staff. Everyone has gathered for a single purpose.
──Tonight, there is a star attraction. The last item listed on today's auction list posted on the stage. The entire venue was buzzing over that entry, where even the name was withheld, simply labeled as "Item Number: 774."
