Forsaken Murderer
Lv Ⅱ   0 Chained Wrath	[Single Ally] Blunt dice gain 1-3 Power. Speed is fixed at 1. He wears a straitjacket, but is as free as any man. No amount of chains and restraints is enough to prevent him from committing violence.	Even if my body is tied… I’ll be as free as any man. Release me… Why do I have to be bound! Don’t look at me with those eyes. You’re the most pitiful ones here… You’re not going to keep me shackled with this! I may be a mess now, but you’ll have to fear me all the same.
Lv Ⅰ   0 Metallic Ringing	[Single Ally] Upon a successful Blunt attack, inflict 1 Bind and Paralysis next Scene. (Excludes Mass Attacks) “My head… turning into metal… folds in my brain, being flattened…”	My head is ringing. I can hear the sound of metal, clear and loud… It feels as if my head is turning to cold steel. Is my head actually turning into metal? When I bash my head onto a wall, it makes a refreshing sound. If my head turns into steel, all the wrinkles in my brain will be gone.
Lv Ⅰ   -2 Violence	[Single Ally] Lower the minimum value of all dice by 1, and raise the maximum value by 3. “What’s really pitiful is people like you dying to the likes of me.”	Don’t think that you’ve won by chaining me… ……… Ends… Begins. Ends again, begins once more… When I bash my head onto a wall, it makes a refreshing sound.
All-Around Helper
Lv Ⅱ   0 Recharge	[Single Ally] If the librarian has maximum Light at the start of a Scene, gain 1-2 Haste, and deal +2-7 damage with attacks for that Scene. However, the limbs were equipped with sharp instruments instead of cleaning supplies.	Beepboop… Beep… Out of battery… Please… recharge… to a nearby socket… Please shut down… The helper-bot will switch off soon… Switching to charge mode. You cannot give orders in this mode.
Lv Ⅰ   1 Repetitive Pattern-Recognition	[Single Ally] After every three clash wins, restore 1 Light and gain 1-2 Haste next Scene. The day I was sent to a new home for the first time, I gave them the gift they wanted so earnestly.	When I’m done cleaning, people would always praise me! They’re giving me orders with a loud voice. That means I’m doing a good job. Beepboop~ Piii! Pattern data accumulated. People love to shout when they compliment me. The helper-bot has excellent learning capabilities.
Lv Ⅱ   2 Clean	[Single Ally] Offensive dice gain Power against enemies with slower Speed (+1 Power per point of difference, up to 3). It recognizes a bad mood as a sign that the surroundings are dirty, and promptly enters cleaning mode.	The helper-bot can help you with any household chores! What kind of task do you want me to do? I can help with anything. Contamination scan complete. Initiating cleaning protocol. Beebeebeep~ Beep. Contamination spotted! Proceeding with trash disposal protocol. I will help you with my wide selection of tools.
Singing Machine
Lv Ⅲ   -1 Music	[All Characters] All characters deal +4-8 damage with attacks this reception. They also suffer +4-8 Stagger damage upon taking a hit. Whenever an ally defeats an enemy, they recover 15 HP and Stagger Resist. But nothing could compare to the music it makes when it eats a human.	Nothing makes as fascinating music as a human can. Don’t you want to hear a beautiful song? You already know how. Don’t you worry. I’m sure that one wants to be a fine instrument, too. People all carry musical talent in them. Those who are fortitudinous, come to me. Join me.
Lv Ⅰ   -1 Rhythm	[Single Ally] For the duration of the battle, gain 1 Rhythm at the start of each Scene. Whenever a character with Rhythm makes a successful attack, a random character gains 1 Rhythm at a 25% chance next Scene. (Rhythm: Gain 1 Strength, take additional Stagger damage from hits, lasts 1 Scene) It was creating a rhythm.	Everyone wants to hear my song again. Various sounds join together to create music. They’re all volunteering to be instruments… If everyone threw their bodies into me, it’ll certainly create an even sweeter melody. You won’t want to hear any other music anymore.
Lv Ⅱ   -2 Musical Addiction	[Single Ally] Offensive dice gain 1-3 Power. Defensive dice roll 1. After all, art is a devil’s gift, born from despair and suffering. Never stop performing until the body crumbles to dust.	All other music is nothing more than noise to me… Make me move… Light my path with the songs! Hahaha… Ha… What will I do? What can I do? Haha… Eternal happiness would be mine if this tune lasted forever… Yes! This is it… Behold this powerful melody!
The Funeral of the Dead Butterflies
Lv Ⅱ   1 Eternal Rest	[Single Ally] Deal +2-7 damage and +2-5 Stagger damage against the enemy with the lowest current HP. People believed that they would become beautiful beings with small wings when they died. It’s a silly story. Nonsensical too.	An eternal rest… May you rest in peace. They believed that they would become beautiful beings with small wings when they died. I’ll help liberate you from tormenting yourselves. They must have returned home, having earned what they wanted and being full of hope. Death may seem fearsome, it doesn’t compare to the terror of reality. It’ll feel liberating, rather.
Lv Ⅰ   0 Lament	[Single Ally] Deal +2-4 damage against an enemy with a status ailment. If the librarian has a status ailment at the start of the Scene, gain 1-2 Strength. They say the mourner with a huge luggage on his back had come to be a savior to all.	For you poor souls who cannot stop grieving… I offer my condolences. Grief for the dead, and early lament for the living. Frivolous forms of sadness such as tears will only wet the wings. Not a sliver of impurity is allowed for the mind of those who mourn, for it must remain reverent and solemn. Not a single proper flower blooms to honor the butterflies.
Lv Ⅲ   1 Coffin	[Single Ally] On hit against an enemy whose HP is at 50% or lower, Seal one Speed die of the target (Twice per Scene, Excludes Mass Attacks). He’s carrying a coffin. A large coffin to pay tribute to the employees who have nowhere else to go. It is still too small to comfort those innocent sacrifices.	A single coffin to pay tribute to those who had nowhere to go, wandering with the memory of an empty faith… Where does one go when they die? The weight of the butterflies that died in vain would be too great to carry. That large coffin, simply too small to comfort those innocent sacrifices. The fragile wings will keep fluttering, waiting for the moment to fall asleep.
Der Freischütz
Lv Ⅰ   2 Request	[Single Ally] When there is no ‘Requested Target’ present, the first enemy the selected librarian hits is marked as one. Deal +3-5 damage against the Requested Target. When the selected librarian defeats the Requested Target, fully recover Stagger Resist, and resolve twice as many books. Just as the Devil said, the bullets will puncture anything you please. Forever.	Some call him a righteous hunter, while others would call him a bloodstained gunman. The bullets always travel across a straight line, along the horizon. I simply follow my impulse, pointing my rifle as I like. The advancing bullet has no morals, no good or evil intent. Sometimes I helped those in need or fought evil.
Lv Ⅱ   -1 The Seventh Bullet	[Single Ally] Deal +1-7 damage with Offensive dice. When an Offensive die draws or loses in a clash, deal damage equal to the dice value to the opponent. Every 7th Melee or Ranged page targets random characters, including allies. The Devil proposed a childish contract: The last bullet would puncture the head of his beloved. The moment he heard that, he sought and shot all the people he loved.	The last bullet will puncture the head of your beloved. You’re right… This magical bullet can truly hit anyone just like you say. The bullets will puncture anything you please. Forever. No bullet will ever be the last.
Lv Ⅲ   0 Dark Flame	[Single Ally] For the duration of the reception, the ‘Endured/Ineffective’ resistances of all characters change to ‘Weak/Fatal’. Gain 1-2 Haste and 2-4 Strength each Scene. One day, the marksman realized the Devil no longer followed him. He pondered why, then realized that his soul had already fallen to Hell from the beginning.	Was it despair that he wished for? My soul began to burn bit by bit, until it ultimately descended to Hell. When one feels there’s nothing left to aim for, their soul falls down to Hell. The despaired heart couldn’t go out in a passionate flame. It would only burn with a cold fire. The despair shall linger around you at all times.

Trivia

• The collective theme of the Abnormalities of this floor in some way reflect killing innocents, whether it be out of urge or necessity.
• According to Yesod, some of the moving gears found in the background of this Floor "don't quite mesh well together", producing loud noises which Yesod finds irritating.

Behind the scenes

• The background art for the Floor of Technological Sciences' story scenes was changed during development. The original image had disorganized bookshelves, while the new background showed all of the room's shelves neatly organized. This was done to better match Yesod's personality, as developers felt the original did not fit his organized manner. The other noticeable change is that in the newer background, the crescent on the tower outside the window also glows, and the entire window is brightened.
