Casino Resort Nazarick (Event)

Casino Resort Nazarick (カジノリゾートナザリック) is a game event in Mass for the Dead that was released on May 16, 2022 to May 31, 2022.

Background
A "casino" is built in Nazarick. This to verify human psychology and whether recreation in Nazarick is sufficient. But how did Narberal Gamma and Solution Epsilon become dealers?――

Incident
At the staff cantina on the 9th Floor, there is talk between Foire and Cixous about a new facility that is being built on the floor on one of the vacant rooms. The news comes from a maid that was serving Momonga and relayed that Demiurge is supervising the interior design and the new area will be for recreational purposes that will soon be open to all.

Meanwhile in the room under construction which turns out to be a casino, Demiurge and Momonga speak on the progress done so far. Everything appears to be set from the coz environment to the gaming tables. The protagonist inspecting the room believes that it is ready to help him answer his questions. Before moving on to the final touches, Demiurge asks with Momonga's permission to provide Pandora's Actor assistance in the financial management aspect of this operation in regards to the "chips" for the casino.

Before they can move towards the part of the project, Slimeko enters the area to inform them that Narberal Gamma and Solution Epsilon have returned from the outside world. The group then reconvene to the Round Table Room, where Momonga addresses the two maids returning after a mission. Both women learn about the casino which is being built in Nazarick. For the reason why it's creation, the protagonist explains that recently the issue of illegal gambling has been rampant in the city of E-Rantel which he manages as Territory Guardian.

The protagonist needing to create countermeasures for this behavior was at a loss of how to handle it, since he lacks an understanding on gambling. The admission of lacking in knowledge comes to a surprise to the maids, though it is attributed to the unpredictability of human behavior in gambling. So far the information the protagonist has comes only from texts, which call gambling a form of competition of losing profits through accidental victory or defeat, and thus is incomprehensible to him. Thus the casino on the 9th Floor was created to serve as a test area to explore gambling to understand human psychology. However the new casino provides new opportunities such as for Momonga as a form of recreation for the NPCs, while Albedo and Demiurge want to explore its benefits to promote their puppet state plan for the Tripartite Alliance. Once all the games are tested in Nazarick, Momonga plans to export some of the casino ideas outside for humans to further Nazarick's influence.

The discussion then turns to why Narberal and Solution were called before the Overlord. The two having infiltrated human society successfully were selected in the casino experiment and assist the protagonist. Needing to replicate the real atmosphere of a casino, they were to play the role as gorgeous dealers for the games. The two maids are ordered to begin studying for their roles which they comply.

Later in Momonga's office, the Overlord has a discussion with Demiurge and Albedo to talk about how to handle the assets of individuals at the casino. Since the NPCs of Nazarick had no salaries, Demiurge recommends that they utilize gambling chips as mediums of exchange at the casino which Albedo agrees maintaining that the subjects of Momonga had no need for salaries. Momonga though while understanding that the casino experiment is to assist the protagonist, hopes that it will provide an appropriate stimulus for the NPCs in their daily lives for leisure. To contribute to the casino, Albedo offers to make prizes to serve as a usage of the chips for the gamers at the casino. Demiurge and Momonga knowing Albedo's talent in making hand-made goods for the Adventurer's Guild give her permission. Momonga seeing off a motivated Albedo then heads to Ashurbanipal to check on the learning progress of his casino dealers.

At the library, Narberal, Solution Slimeko and the protagonist are hitting the books on all casino related material for their roles as dealers. From their study session they learn that a dealer is a customer-service role in a casino whose job is to entertain guests and players. And on top of that they are charged in paying the dividends for each game while being the facilitator of the games played. The trio find there to be a lot of rules to remember. Not only that there are several techniques that the dealers need to master. The games present at the casino are "roulette" and "baccarat" which will be handled by Solution and Narberal respectively. In "baccarat" Narberal muses that she will have to learn how to card shuffle effectively, which she finds to be very human and a game that can be easily flinched. And while the game is simple as with win or lose, there are variations of betting methods.

As for "roulette" Solution finds that the game involves throwing a ball into a disk with numbers and guessing the outcome, while seemingly simple it gets complicated in various ways depending on the payout, from the outside bets and inside bets based on colors or specific numbers. The protagonist notes that beside skill, luck is also a factor in the games and Narberal admits that the profit and loss are not uniform when gambling as it is up to the gamer to decide the degree of risk and return. For practice, Slimeko offers Narberal the use of a deck of playing cards she took from the Treasury. Whilst trying to shuffle the cards as instructed by a book, Momonga appears pleased at their dedication. His sudden appearance startles Narberal who hastily greets her her master. Momonga seeing that his presence caused the group a start apologizes much to the group's shock. Happy to see them diligent at their work, Momonga leaves after giving them a few words of encouragement for their casino roles. After leaving the library Momonga hopes not only that maids can play out their roles but also enjoy the experience.

In Albedo's room, the Overseer Guardian is busy at work with making various hand-made goods as prizes for the casino. The demoness is happy at the feeling of doing her hobby, making copies of Momonga, still longs to touch the real thing, though begs herself to be patient, reminding that the dolls she is making are for the Floor Guardians at the casino. A knock is received at her door which turns out to be Momonga to her delight. Momonga enters wanting to see her end of the preparations. Eager to please her master, Albedo showcases Momonga a preview of the line of products she already crafted. The variety of products amazes Momonga and learns that Albedo intends to provide as many different products that would suit the tastes of the customers, centered on every day items. Since nothing more needs to be said, Momonga expresses his gladness at viewing Albedo's finding joy in her endeavor.

In the Pleiades' dorm, Narberal and Solution demonstrates their newly honed card shuffling and betting skills to Lupusregina Beta, Entoma Vasilissa Zeta and CZ2128 Delta in preparation of manning the baccarat and roulette tables at the casino. Narberal is confident that she will fulfill her role as a dealer at the table, having enough practice, while Solution hopes something similar can be done before the opening of the casino.

The next day the grand opening of the casino was officiated to start the experiment. The Floor Guardians and Pleiades gathered to the new room on the 9th Floor where they are welcomed by Demiurge to the Casino Resort Nazarick.
