After the Crystal Gems fail to destroy the Cluster, Yellow Diamond herself comes to Earth to retrieve it. Desperate to save Earth, Steven makes a deal with Yellow Diamond - he'll go with her to Homeworld as a new subject if she helps terminate the Cluster. With Peridot as his only friend aboard the Yellow Diamond's ship, Steven must learn how to adapt to Homeworld culture, while Peridot slowly realizes that her time on Earth has changed her more than she'd admit.
And, of course, Yellow Diamond has her own problems to deal with as well...
The comic went on an indefinite hiatus in September 2017. On July 2018, the author confirmed on their tumblr that the comic is now cancelled, and that they would make closure post(s) of what was going to happen in the story.
New Home contains examples of:
- Adaptation Personality Change: The comic began late during the show's second season, months before we saw Yellow Diamond for the first time in "Message Received". While Blue Diamond was briefly seen during "The Answer", we didn't learn her personality until season four's "Steven's Dream". And White Diamond isn't even spoken about until her debut at the end of the fifth season, in "Legs From Here to Homeworld". The creator had to craft their personalities from scratch as a result.
- While there manage to be similarities between the canonical YD and her "New Home" counterpart, such as her interest in Earth, the latter is more impulsive, emotional, and a bit of a Snark Knight that the other diamonds don't trust: they gave her Amazonite as an alternative to being shattered, as they feel she's just as dangerous as Rose Quartz.
- Blue Diamond is nothing like her canon version, with her first appearance in the comic having her deriding Yellow Diamond for her emotional vulnerability; something that YD derides HER for in the show.
- All Just a Dream: In Chapter 2 Steven has a dream that he's talking to the Crystal Gems despite them being back on Earth. Steven realizes that this is impossible and must be a dream, but proceeds to speak to them anyway as if they weren't.
- It happens again in Chapter 5 when Steven has another one, this time with just Garnet.
- Alternate Continuity: The comic diverges from the show starting from "Catch and Release", though it's implied that much of Peridot's character development from subsequent episodes still occurred while building the drill.
- Berserk Button: Yellow Diamond doesn't react well when Steven says she and the Crystal Gems aren't so different.
- Break the Cutie: Steven learns the hard way that life on Yellow Diamond's ship is not going to be all that happy.
- Cheshire Cat Grin: White Diamond.
- Color-Coded Elements: Each of the Diamonds has their own distinct color and elemental powers.
- Yellow Diamond - Fire
- Blue Diamond - Water
- White Diamond - Lightning
- Emotionless Girl: Yellow Diamond. Almost always she is seen with a stoic expression that's difficult to read and makes it tough to know what she's thinking.
- The Empire: Homeworld and The Diamond Authority.
- Explain, Explain... Oh, Crap!: When Steven wonders why the ship has yet to leave the solar system, Peridot explains how Yellow Diamond is neutralizing the Cluster. As she explains, she jokingly wonders what the Crystal Gems' reaction would be to seeing so many Homeworld Gems running around...only for her and Steven to realize that the Crystal Gems have likely been fighting said grunts and impeding their efforts.
- The Fake Cutie: Amazonite.
- Heroic Sacrifice: Although he doesn't actually die, Steven gives himself up to Yellow Diamond in exchange for the Earth being spared.
- Hidden Agenda Villain: Yellow Diamond. The rest of the Diamond Authority is unsure how to handle her as a result.
- Humans Are Cthulhu: Yellow Diamond has been shown to be freaked out by Steven's organic nature and "squishiness" to the point she loses her stoic face when he initiates physical contact with her.
- Humans Through Alien Eyes: Peridot has to explain Steven's human qualities to Yellow Diamond, even though she has a limited grasp of them herself.
- Killed Off for Real: The Carnelian Steven has to fight is shattered by Yellow Diamond at the end of Chapter 1.
- Morality Pet: Steven might be this for Yellow Diamond, as she spares Lion, arranges for him and Peridot to remain together on this ship, and prevents everyone else on-board from learning that Steven's gem is the same as that of rebellion leader Rose Quartz. However, the bonus comic "Cleave" implies that she's always been like this.
- Steven also serves as this for Peridot, who readily defends him and looks out for his well-being.
- Scary Teeth: White Diamond.
- Slasher Smile: White Diamond at all times.
- Stealth Hi/Bye: Yellow Diamond has a knack for showing up unnoticed.
- Stranger in a Familiar Land: Peridot regularly lapses back into the behavior and beliefs she developed while on Earth, and is rendered mute whenever other Gems point out her odd actions.
- Undying Loyalty: Lion is so loyal to Steven that he warps onto the ship to get him back.
- You Can't Go Home Again: Steven can't return to Earth due to the agreement he made with Yellow Diamond.
- You Didn't Ask: In Chapter Four, when Steven goes on a tirade about how little they know about what Yellow Diamond is planning and states that they have to find out what's going on, Peridot causally responds that she already has a good idea of what's happening. Steven is too tired to be angry about this.
