## Summary

### Camp Lily

After wandering into the accursed Execrated Forest, Coco is caught by Indefinable Shadow Beasts and imprisoned inside a roomba cleaning device, having her name changed to Cocorobo. This leads to her going missing until she is found by Lily, Gumi, and kokone in an abandoned ranger cabin. She tells them about the blessed Fountain of Diolacov that can cure any ailment, so the trio agrees to bring her to it. The cabin is then surrounded by the shadow beasts. Gumi creates a diversion that allows Lily to escape with Cocorobo, but she and kokone are captured in the process. Lily is able to climb on top of Cocorobo, who then flies across the forest by activating her vacuum powers.

While exploring the forest for a day, Cocorobo promises to become Lily's servant if the latter is able to heal her. The two come across the Fountain of Diolacov and Lily is able to bring Coco back to her human form. The two are then captured by Indefinable Shadow Beasts along with the possessed Nekomura Iroha and Suzune Ring. Along with the other captured campers, they are set to be sacrificed to the forest, but a fight breaks out and they are able to escape. Lily heals Iroha in the Fountain of Diolacov before the humans are chased away by Ring and the ISBs. Having retained her vacuum powers, Cocorobo is able to fly everyone into the trees, where they are rescued by Otomachi Una in a helicopter.

### Life with Lily

As promised, Cocorobo becomes Lily's personal servant and moves into the Internet household. She regularly cleans and cares for Lily, frequently performing tasks such as giving her massages, styling her hair, and brushing her teeth. When Lily is conflicted by the hate she receives as a musician, Cocorobo and kokone attempt to console her. When she becomes obsessive over it, the two plot a scheme to show that hate is a natural occurrence. Cocorobo disguises as a hater to seemingly insult kokone in front of Lily, but a real hater shows up instead. This only solidifies the lesson for everyone involved.

When Lily wins a mansion in a contest held by Iroha, she and Cocorobo move into it together. She quickly becomes territorial over the kitchen and other crucial areas of the house. It later turns out that the mansion is haunted by a monster. Not believing this, Lily invites thirteen guests to the mansion to see if they can spend a night without leaving. Early on, IA, Yuzuki Yukari, Tako Luka, and Uni enrage Coco by making a mess of her kitchen. When the power mysteriously goes out, Cocorobo sends them to the generator in the basement as punishment. It is there that the monster first attacks. The guests are terrorized by the monster while Lily and Cocorobo relax in their own quarters. Overnight, Cocorobo is taken hostage by Gumi, CUL, Sachiko, Maika, and Merli, who interrogate her on the monster's identity. However, when she and Gumi are captured by the monster, her potential involvement is disproven.

The monster later turns out to be Lily's old bandmate and ex-girlfriend Luna. Lily and Luna are able to make up before the mansion explodes from a planted explosive, giving everyone time to escape beforehand. Without a mansion, Lily and Cocorobo move back in with Internet. They also retain contact with Luna. Lily, kokone, and Cocorobo regularly hang out, becoming an established trio of friends.

When Lily is rejected from performing at a major Christmas concert, she is devastated, but Cocorobo and kokone attempt to cheer her up. She dismisses their attempts and insinuates that their friendship is purely business-related. Overnight, Lily's long-time enemy Namine Ritsu approaches Cocorobo with a fortune, giving her the opportunity to leave Lily in exchange for a hefty payload. She is given time to consider it, but after a night of evaluation, Lily apologizes to Cocorobo and the two make up. Cocorobo declines Ritsu's offer, declaring loyalty to Lily.

Cocorobo is invited to speak at a "cleaning equipment convention," having the experience of being a roomba herself. This causes her to leave a distressed Lily for the weekend. Lily hires a replacement maid, Acme Iku, to temporarily handle the housework, but the maid proves to be catastrophically terrible. Cocorobo comes home just in time to save Lily from a lethal massage and she beats Acme Iku in a fight. Lily apologizes for trying to replace Cocorobo and accepts that her friends will not always be there for her physically.

### Enlightenment

After being inspired by Megurine Luka, Lily starts a "vocagrunge" band with Cocorobo and kokone called Enlightenment. As none of them know how to play instruments, they learn from Luna. They are an instant success and outsell every other vocaloid singer, including the megastar Hatsune Miku. Soon, celebrities catch onto their trend and outsell them, but when it dies as a music fad, Enlightenment is able to continue as the definitive vocagrunge band.

Cocorobo continues to play with Enlightenment until they are booked to perform in the Execrated Forest. Upon arrival, they discover the booking to have been a farce set up by Ritsu. While Ritsu and Lily argue, Coco hears a strange noise and goes to investigate it, only to be captured by Ring and brought to Aoki Lapis as a prisoner along with kokone, Sonika, and Luna. They are held until Lily, Merli, and Iroha show up to rescue them, forcing Lapis and her minions to flee their kingdom. They are then visited by Prima, who claims to have been watching Lily. She explains that Lapis is after a sacred artifact blessed by the goddess LUMi, VY1, and Lily must find it before she can.

### Deep Sea Lily

Cocorobo awakens on a vessel underwater along with Lily and sixteen others. They are then debriefed on their mission by Prima, who gives Lily LUMi's sacred sword VY2 and places her in charge. She warns them that Lapis is staying in an undersea castle along with Ring, Ritsu, and Violet, and that she is controlling the fish to find VY1 before Lily's team can. She also tells them about Solaria, who they are meant to keep an eye out for. When the group sets off, they are attacked by a giant anglerfish that eats Iku, so Cocorobo grabs Lily and flies off with her. They soon unite with kokone and Iroha, forming a group with them. Lily and Iroha frequently argue, which bothers kokone, who is comforted by Cocorobo. Eventually, they find the ruins that contain VY1, but they are ambushed by Lapis and Violet. Merli shows up to fight Lapis as Cocorobo makes off with VY1. She gets rid of it before she is captured by Lapis.

Cocorobo is imprisoned in the undersea kingdom along with everyone else who is captured. During her captivity, Solaria kills Ring to save Kaai Yuki as one of three "favors" she is allowed to grant, LUMi arrives to give Lily a blessing but is soon killed by Lapis, the group comes to possess VY1 through help from Solaria, and Lily is eventually left as the only one alive and uncaptured. Lily is able to save the prisoners with help from Ritsu, who is later killed for betraying Lapis. The reunited team destroys Lapis' castle from the inside before escaping, but Yuki steals VY2 and uses it to kill Lapis. This causes the sword to dissolve. With Lapis dead, Violet takes over the ocean and uses her fish to fight the group. It turns out that VY1 can only be used through a sacrifice, which only Merli is powerful enough to make.

Merli gives her life to open the vortex meant to seal Violet away for eternity. Lily uses LUMi's blessing to morph together with Iroha into "Rio," who then fights Violet until she is weak enough to fight in their regular forms. Lily sacrifices herself by dragging Violet into the vortex, causing Cocorobo and the others to mourn, but Solaria uses her last favor to teleport Lily away at the last second. With everyone reunited, Solaria disappears and the surviving team members return to the surface.

## Characterization

When silylilyanimove's admin had a YouTube channel that regularly posted videos discussing *Vocaloid* characters, they made a video addressing the cancelled character Cocorobo. The video was a success and became the subject of several jokes on both the admin's personal Twitter page and silylilyanimove. When Camp Lily started shortly after the video's posting, Cocorobo was added to the plot as a joke. Her inclusion was well-received and upon the conclusion of the story, she remained a character who frequently appeared in memes on silylilyanimove. Continuing her obligation to become Lily's personal servant, Cocorobo was regularly featured alongside Lily, acting as either a maid or a mentor. A running joke involved placing her in the background of memes that had nothing to do with her. Following the establishment of the silylily continuity, Cocorobo's role in Lily's life received expansion and she became one of the most important characters in the series. The trio of Lily, kokone, and Cocorobo has become an identifying asset of silylilyanimove, the admin deeming them "unpopular vocaloids no one would ever expect to see together."

## Trivia

* Despite her significance in Lily's life, Cocorobo is absent in many comics from Kokone's Job through Lily's Mansion. This was due to her being a less recognizable Vocaloid character that may have been harder for audiences to sympathize with.
* In No More Silliness, Cocorobo is seen with the head of Sonic the Hedgehog and remarks she has "turned into hedgheob."
* Lily asks Cocorobo to a dance in Lily Needs a Date, but Cocorobo declines due to being busy with tasks given to her by Lily herself.
