LittleMass

LittleMass () was an idol group of the Great Tomb of Nazarick in Mass for the Dead.
== Background ==
After the protagonist was hailed a hero for driving away the Demon Emperor Jaldabaoth from E-Rantel, the homunculus hero brought a proposal to Momonga and the other Floor Guardians that it was in Nazarick's interest to care for the well-being of the fortress city. Having made tours
to the new and old sections of E-Rantel, the protagonist made an observation that while humans and demi-humans coexisted in the new section, there were many people were still suffering from trauma of the
Catastrophe in the old section. If left unattended, it could lead to a possible conflict between the two areas of E-Rantel. To avoid that scenario, it was decided that not just physical assistance to the city was
needed but to provide mental relief. It also prompted an opportunity to seize the hearts of human inhabitants. Among the ideas of what method they should use, it was Momonga's suggestion of using idols that was
put to play. 
== Chronology ==
=== Mass for the Dead Arc ===
Before implementing the idol event in E-Rantel, a trial run was agreed to be done within the Great Tomb of Nazarick and for the Homunculus Maids in consideration that they were similar to humans and to reward them for their efforts in maintaining Nazarick. Though it was suggested that the Pleiades would make good idols for this event, the roles were given to the Floor Guardians as the battle maids already had many missions to follow-up on. Two Floor Guardians were selected for the idol singers and made their surprise debut at the canteen on the 9th Floor where they gave a small show to the general maids.
Demiurge acting as the producer for the idol show and the protagonist as the manager together did some research on idol singing shows. In order to give the general maids a truly interactive experience Demiurge wanted to do a live idol show in a setting where the homunculi would feel a foreboding environment and be uplifted in spirit by the idols. The ruined Throne Room was selected to be perfect with the idols not just singing but also battling against the Chaos Beasts that emerged periodically. The plan was proposed to Momonga, though he had reservation of putting non-combatants in danger but after measures were taken to ensure the security and safety of the spectators, the Overlord consented to the plan. To test out the live idol show, a trial run was agreed before taking the show on the 10th Floor. 
To start the first actual live idol performance took place on the 6th Floor in front of the Crack anomaly there. The event turned out to be a success by Momonga who viewed the scene via his undead summon. Plans to proceed to the show on the 10th Floor were approved and also the start of creating idol merchandise for the maids.Mass for the Dead Special Event: (Part 1) Underground-Tomb-IDOL P
After commemorative goods were given out, such as autograph cards and hand-signed towels at festive locations like Spa Resort Nazarick, the second campaign for the idol plan went into effect. The next show took place in the ruined 10th Floor within the Throne Room before a crowd of general maids and their security guards. The crowd watched as the idols Acidity and Alkaline fought against the invaders from the Crack in awe at the fight and realizing the power the Floor Guardians face every day for them.
A few days after the start of the second drive of the idol plan, Cocytus finds a large line of maids outside the canteen being ushered in an organized fashion by Mare. There the maids are given more
autographed goods and chance to meet the idols in person. Demi P seeing Cocytus and Mare are present convince the two to partake in a surprise live battle show with the idols much to the glee of the maids. 
The idols take a break from the event and are visited by Albedo who came to give her thanks to the two of them for their hard work. Though she also adds the shame it is for them to be sacrificing their candidate
places in the Queen War, as the literature in idol material clearly state no romances are allowed for them. In other words they were no longer qualified to be Momonga's queen due to the restriction. Shalltear hearing that piece of news was furious and led to her decision to disband the idol group at the end of the second campaign. The revelation was of course all part of the plan composed by Demi P so that the disbandment of LittleMass would spread among the maids and drive its popularity and fanfare through the roof. He hoped to produce an effect where the final show would produce the greatest turn out.
The final show takes place in the Amphitheater where a grand stage has been set based on specifications from idol literature. There the idols perform their last sow before their fans. The Corpse Guardian
is brought out to be their newest opponent. Once LittleMass defeat it, Momonga personally comes out to show his gratitude and present the Staff of Ainz Ooal Gown to the audience and casts a spell to summon a
Primal Fire Elemental as Acidity and Alkaline's last opponent for the finale.
Once the idol plan came to a conclusion, the general maids went back to their usual routine. Though they believed it was a pity the idol group disbanded, the show motivated them to work harder to repay the Floor
Guardians and Momonga. The success of the plan convince many Floor Guardians that it was feasible to implement in E-Rantel. Momonga while admitting it was sound, advised that they should keep the idea on standby
as E-Rantel contained religious forces like the Slane Theocracy who may take offense. Shalltear though was all for the idea to revive LittleMass on they day it was brought to E-Rantel, as she found a loophole
in the no romance rule for idols, believing that scandals can happen but so long as she has talent she can still be with Momonga. Albedo irked by Shalltear's confidence tries to get Momonga to make her into an
idol and is also followed by Mare leaving the Overlord at a loss on what to do.Mass for the Dead Special Event: (Part 2) Underground-Tomb-IDOL P
LittleMass would be reformed again at the "Nazarick Swimsuit Athletic Meet" at the Open Bath Spa where Acidity and Alkaline provided a live mini-show for the interim between the second and final competition. Pandora's Actor was the special guest who battled against the two idols at the venue.Mass for the Dead Special Event: Queen War -Nazarick Swimsuit Athletic Meet-
For Nazarick's first formal Halloween Festival, Aura considered donning her LittleMass idol attire for the occasion, but decided not to as the costume required it to be a set with Shalltear, who wanted to instead dress in her adventurer "Shall" identity.Mass for the Dead Special Event: Witches' Costume Party
After the success of the idol group with the general maids, it was applied in E-Rantel, though using the protagonist's "Dark Warrior" identity as the the theme. Under the moniker and working through the Adventurer's Guild dolls, chocolates and merchandise were distributed as products. In turn it boasted the revenue of the guild as well as drove employment of the adventurers. The Sorcerer Kingdom also gained a fair bit of foreign currency due to their investment in the marketing out their hero in the city. However it drew some concern from the members of the Sunlight Scripture who were worried that fans who were drawing on the hero worship might turn into something religious and be the cause of incitement to riot. At the same time the Adventurer's Guild seeking to expand it product line wanted to release some new merchandise associated with the "Dark Hero". The protagonist vowed to resolve these two issues of the Theocracy and guild. One of the plans suggested that was suggested was develop the new product line that would appease the guild's need to expand and also drive attention away from the "Dark Warrior" and to another member of Darkness or even a new character. 
Before committing the plan to E-Rantel, a test was planned to see how fans would react. The test would see whether fans would be loyal to their idols or be discouraged, and thus LittleMass was called again to assist Nazarick. However this time a new character would be introduced and a live show was set to debut. Said new idol was selected to be Albedo debuting as Neutrally. After the debut Demi P commemorated the new star's inclusion by renaming idol group as LittleMasStar.Mass for the Dead Special Event: Underground-Tomb-IDOL 2ndP
