"Kaseki!"
―Kaseki Grumer's repeated line.

Kaseki Grumer (カセキグルマー Kaseki Gurumā, lit. Fossil Grumer) is a Fossil-Themed Kurumaju from the Great Space Invasion Running Team Hashiriyan.

History

The Trio discover a digital sign for a museum exhibit on dinosaurs and Yaiyai is impressed that such fearsome creatures existed on the planet Earth. Dekotorade says that they should be getting back to work, with the three of them racing inside the museum to find a dinosaur that they can use to make a Kuramaju. They infiltrate the museum by disguising themselves as workers unloading the crates of fossils that will be put on display, stealing the fossil of a Simiasaurus that was to be the main attraction of the exhibit. Ittasha then places her Ignition Key into the bones of the extinct creature.

Outside, Jou hears the loud scream of the museum curator while walking close to the entrance of the museum loading dock and rushes in to see what is wrong, only to come face to face with the newly formed Kaseki Grumer. Kaseki just stands there menacingly as the Trio order him to attack Jou but Kaseki steps back and hesitates a bit. The others arrive and they all transform together, but when Taiya tries to start a roll call, Kaseki charges as if to ram the Boonboomgers. The Rangers are taken by surprise when Kaseki jumps over them and runs away scared, much to the chagrin of the Trio who wonder what went wrong. Ittasha thinks that maybe using something so old somehow made their new monster defective.

The team search the city and check in, with no luck finding Kaseki, Taiya radios everyone to keep looking. Bun Bun finds it odd that a Kuramaju would run away instead of starting a fight, but Taiya speculates that the dinosaur its fossil base components are made from was a skittish and shy creature and it copied those traits. Jou searches further and finds Kaseki in the bushes, trying to approach him carefully so he doesn’t run away but Bun Bun calling scares Kaseki. Kaseki tries to run but he is too weak from hunger to get very far, Jou shows compassion to the monster and gets him away from frightened civilians.

Hiding in a parking garage, Jou now has a dilemma as Kaseki does not want to hurt anyone and it would be wrong to attack an innocent living creature, but he and his team have to retrieve the fossil. Genba suddenly appears and wants to help, offering the keys to a warehouse to help Jou hide Kaseki and instructs him to sneak through the emergency exit to avoid being spotted. Jou thanks him and takes Kaseki to the warehouse, with Genba amused about the “lonely little dinosaur”.

Jou returns to the warehouse a few hours later with food for an excited Kaseki who knocks him over and nuzzles him like a pet happily welcoming his master home. Jou bought meat and plant foods as well as fish to cover whatever diet that Kaseki has naturally, only for the dino to take and eat the cream puff that he had bought for himself. Jou is upset at first but decides that as long as Kaseki is happy it is fine.

Kaseki continues to eat and Jou gets a call from Taiya, who has been informed by Genba of the situation. Jou apologizes but Taiya asks what he is going to do next, Jou is uncertain if they need to fight as he is sure that Kaseki will not attack anyone. Taiya asks if Jou can prove that, which Jou is hesitant to answer but decides to spend the night with Kaseki to prove he isn’t dangerous. Taiya allows him to do so, with Ishiro asking if he’s really okay with Jou’s plan, with Taiya just silent and wondering himself.

Kaseki is upset because he heard Taiya, but Jou comforts him and tries to get some dinner, only to see Kaseki has eaten all the food, but the dino nuzzles him again and Jou just pats his head.

Jou spends the evening trying to keep watch over Kaseki, but accidentally falls asleep for a bit and panics when he wakes up, only to see the dino playing with a yoga ball like a cat playing with yarn. Jou is relieved and goes back to sleep, only to wake up having a little trouble breathing hours later and seeing Kaseki sleeping and resting his head on his lap, with him then resting his head against Kaseki.

In the morning, Jou finds that Kaseki had stayed with him all night and didn’t go out to attack people. He asks Kaseki if he is going to promise not to attack anyone from now on, which the dino agrees to. Jou decides to name his new pet dinosaur “Keytarou”, then hears the growling of Keytarou’s stomach, laughing and deciding to go out to get breakfast for him. Upon opening the shutters, Jou comes face to face with the Sanseater Trio and a platoon of Neijiretta, who plan on capturing Keytarou and bring him back into the Hashiriyan. Jou changes into Bun Black and tries to protect Keytarou, only for Dekotorade and Ittasha to grab him and drag him out of the warehouse. Jou frees him and tries to encourage Keytarou to run away on his own, only for Yaiyai to attack him and demand that the Ranger return his dinosaur to him. Jou grabs Yaiyai and throws him, sending him flying and crashing hard onto the pavement with Dekotorade and Ittasha checking on him and once Jou and Keytarou are surrounded, the Trio throw a net and capture the two. Fortunately, the rest of the Boonboomgers show up and free Jou and Keytarou while driving off the Nejiretta. Taiya wants to support Jou, as he has proven that Keytarou is a good monster. The team are going to defend the two until Jou gets Keytarou to safety, with Ittasha sending out more Nejiretta to try and stop them.

In all the commotion, Cannonborg manages to attack from above to modify Keytarou and infuse him with Ghassolin. Keytarou loses his innocence and free will and becomes a savage monster with a drive to destroy, while Jou is at first confused by this as Kaseki attacks the Rangers, the Trio blurt out that their commander is probably behind this. Jou tries to snap Keytarou back to normal but gets pulverized and knocked out of his transformation trying to do so. Jou is heartbroken and continues calling out to Keytarou, who at first seemed to respond to Jou but then the modifications to its mind suppressed those thoughts as it writhes in pain.

The Kaseki Grumer suddenly grows on his own without the need for Yaiyai to enter Highway Space and rampages through the city. Cannonborg is disappointed with the results of his little experiment, the side effects of his little “tune up” did not turn out as he expected and he wasted more Ghassolin as a result rather than creating more as Kaseki consumed what he infused into him.

As Kaseki continues to rampage, destroying buildings and trapping and injuring civilians, Jou is horrified and shocked as the rest of the Boonboomgers rescue civilians. Jou pleads for Keytarou to stop and screams in frustration when he doesn’t listen, blaming himself for what has happened, saying that he failed to do his duty as a police officer to protect everyone and his choices led to this.

Taking responsibility, he tells Taiya that he will personally take care of the Grumer himself. Jou transforms and calls Bun Bun into battle, forming Boonboomger Robo Monster and pilots it. Taiyo asks if he will be alright, but Jou says he needs to handle this matter. The Trio cheer on their dinosaur monster, who proves strong enough to match Monster blow for blow. The battle goes on until sunset, with Jou remembering Keytarou as he was and cries, saying how sorry he is for what he is about to do. Jou hesitates to activate Monster’s finisher but does so and in his sorrow delivers the final blow. Before he explodes, Keytarou returns to normal, making Jou’s actions all the more painful to him.

Personality

Unlike other Kurumaju, Kaseki Grumer was nonviolent, taking on the behavioral patterns of a real life Simiasaurus and fleeing from battle. Jou was able to gain it's trust, at which point Kaseki Grumer behaved like a friendly pet around Jou. It only went berserk due to Cannonborg's modifications, although Kaseki Grumer seemed to regain it's original personality seconds before being destroyed.
