You’re probably here because you just got your teeth kicked in by a specific realization or a specific boss fight in the Social Sciences floor. It happens. Chesed Library of Ruina is a name that carries a lot of weight for fans of Project Moon’s universe, mostly because he’s the guy who looks like he’s having a great time while the rest of the world is literally burning to the ground. He’s the coffee-obsessed Sephirah who somehow maintains a sense of chill in a library built on blood and trauma.
But there is a lot more to him than just a caffeine addiction and a light blue aesthetic.
If you’ve played Lobotomy Corporation, you already know his backstory is a nightmare. In the transition to Library of Ruina, Chesed (formerly Daniel) becomes the emotional anchor for a lot of the game’s philosophical heavy lifting. He represents the "Will to Trust," which sounds like some cheesy shonen anime trope until you realize the context of the City. In a world where your neighbor would sell your organs for a coupon to a mediocre ham-hampangeux place, trusting someone is a radical, almost suicidal act.
The Reality of the Social Sciences Floor
Most people focus on the combat. That's fair. The Social Sciences floor is weirdly technical. It’s not about raw power like Gebura’s Red Mist shenanigans or the utility of Yesod’s floor. Chesed’s floor is about manipulation—specifically, manipulating the cost of cards and the flow of light.
It mirrors his personality. He’s a guy who works the system.
When you start unlocking his Abnormality pages, you see a theme. You’ve got The Woodman, The Scarecrow, The Cowardly Lion, and The Road Home. If that sounds like The Wizard of Oz, it’s because it is. Project Moon loves their literary references, but they twist them. In Chesed’s domain, these stories aren't about finding a brain or a heart; they’re about the absolute despair that comes from lacking them.
Why the Coffee Thing Matters (It's Not Just a Quirk)
Chesed’s obsession with coffee is often played for laughs, but it’s actually a coping mechanism. It’s a sensory tether. In the City, and especially within the Library, humanity is a fading resource. Drinking a high-quality brew is one of the few ways he can reclaim a sense of "personhood" in a mechanical, bureaucratic nightmare.

He’s also the only one who really pushes back against Angela’s cynicism in a way that isn't just screaming or brooding. He talks to her like a person. He offers her coffee. It’s a small, quiet rebellion against the cold logic of the Library.
Mastering the Mechanics of Chesed's Floor
If you're trying to actually win with the Social Sciences floor, you have to stop thinking about individual strength. You have to think about the economy.
Chesed Library of Ruina gameplay revolves around "Card Cost Reduction."
It’s genuinely hilarious when it works. You can take high-cost, high-impact pages and turn them into 0-cost nukes. The Abnormality page Magic Lamp is a prime example. If you pick it up, you can potentially reduce the cost of all pages in your hand to 0 for a turn. It’s a massive swing.
Then you have the Exertion and False Hope pages. These aren't just "hit harder" buttons. They require you to manage your resources and your "Emotions" differently than you would on the Floor of History or Art.
The Card Interaction Trap
A lot of players struggle because they try to build "generalist" decks for Chesed. Don't do that. You want decks that are heavy on the top end. Since the floor provides so much cost reduction, bringing a deck full of 1-cost cards is a waste of the floor’s potential. You want the big hitters. You want the pages that normally feel too "expensive" to play consistently.

- Focus on Draw Power: Because you’re playing cards for cheap, you’ll empty your hand fast.
- Light Restoration is secondary: If your cards cost 0, you don't need light. Focus on "Draw 2" or "Draw 3" effects.
- The Wizard of Oz Synergy: Aim for the Exertion page if you’re running a glass-cannon build.
The Philosophy of "The Will to Trust"
Let’s get into the deep lore for a second. Chesed’s realization is one of the most poignant moments in the game. It deals with his failure back at Lobotomy Corp—his inability to act because he was afraid of the consequences. He chose the "safe" path, and people died because of it.
In Library of Ruina, his character arc is about moving past that paralysis.
The Social Sciences floor represents the study of how people interact. In the City, those interactions are usually predatory. Chesed argues that even if trust leads to betrayal, the act of trusting is what makes life worth living. It’s a stark contrast to Binah’s coldness or Roland’s initial nihilism.
He’s the guy who sees the "Black Silence" and the "Red Mist" and thinks, "Yeah, but have you tried this dark roast?" It’s not because he’s oblivious. It’s because he’s the most self-aware person in the building. He knows exactly how bad things are, and he chooses to be kind anyway. That is a much harder path than being a jerk.
The Problem With Being "The Nice Sephirah"
Chesed often gets sidelined in fan discussions because he isn't "cool" in the traditional sense. He doesn't have a giant sword or a terrifying bird-mask (well, not usually). But if you look at the dialogue during the late-game receptions, he’s often the one pointing out the logical fallacies in the guests' arguments.
He understands the systemic issues of the City better than most. He knows that the "Head" and the "Claws" aren't just villains; they’re the logical conclusion of a society that has abandoned empathy for the sake of efficiency.

Key Tactical Advice for the Social Sciences Realization
The Chesed realization is a marathon, not a sprint. You’re dealing with the Oz abnormalities, and each phase requires a different mindset.
- The Scarecrow: It’s all about wisdom. Or the lack of it. You need to manage your deck so you don't get your "brains" sucked out. Use cards that have high minimum rolls to counter the wisdom-drain.
- The Woodman: This is a heartless fight. Literally. It’s a damage race. You need to burst him down before he scales out of control. This is where those 0-cost high-damage pages come in handy.
- The Cowardly Lion: This phase tests your bravery. You have to stand your ground against some intimidating rolls. If you flinch, you lose.
- The Road Home and Scaredy Cat: This is the one that trips people up. It’s a puzzle. You have to manage the positioning and the "marked" targets. If you ignore the mechanics and just try to "unga bunga" your way through, the cat will shred you.
Honestly, the best way to handle Chesed's floor is to embrace the chaos. It’s the floor of "What if everything was free?" and "What if we just didn't die today?"
Actionable Steps for Your Next Playthrough
If you want to maximize your experience with Chesed Library of Ruina, stop treating him as a secondary support character.
- Build a "Big Deck" Strategy: Use the Social Sciences floor for your highest-cost Key Pages. Characters like Maxim or any of the Rhino Team members thrive here because their high-cost "Charge" cards become trivial to play.
- Read the Flavor Text: Seriously. The dialogue between Chesed and Angela in the later chapters contains some of the best writing in the game. It sets up the finale perfectly.
- Experiment with the "Magic Lamp": It is arguably the most broken Abnormality page if your hand is set up correctly. Try to trigger it when you have a hand full of 3 and 4-cost pages.
- Don't ignore the "Power of Friendship" buffs: Some of his pages give minor buffs to allies. In the Library, a +1 to power can be the difference between a successful clash and a staggered librarian.
Chesed is the heart of the Library. While everyone else is busy seeking revenge or seeking the "One True Book," he’s just trying to make sure there’s a world left worth living in once the dust settles. That makes him the most dangerous person in the room—because he has something to lose besides his life.
Next time you’re in the Library, bring some high-quality beans. It’s the least you can do for the man keeping the Social Sciences alive.
Go check your current deck builds for the Social Sciences floor. Look for any page with a cost of 3 or higher that you usually avoid because it’s "too slow." Put it in. Let Chesed work his magic. You’ll be surprised how much easier the late-game receptions become when you aren't constantly worried about your light count. Focus on card draw, prioritize the Magic Lamp and Emerald pages, and watch the City's finest fall to a bunch of librarians who are probably vibrating from a caffeine overdose.
