Kokichi was desperate to obtain a 'normal' body and resented being born with no future outside of Jujutsu. This is why he originally hated Panda, a puppet, had the freedom to choose and attend school normally while he was forced to live alone.

Although his cooperation came with the bidding vow they would not attack Kyoto students and he planned on killing both of them immediately after his transformation. It is implied that Kokichi was in love with Miwa.[2]

Shibuya Incident Arc

Sometime later, Kasumi Miwa informs Kokichi that their notebooks are due that day which Kokichi informs her where his notebook is and that he will be asleep for a bit. Kokichi then meets with Getou and Mahito, and complains to them about how they weren't suppose to attack the Kyoto students during the exchange but they simply pass the blame on Hanami. Mahito comments about killing Kokichi, but Getou tells him that they have to heal him first or sometime will happen to them. Mahito then uses his Idle Transfiguration on Kokichi, which restores his body to perfect condition. Once Kokichi is healed, Kokichi and Mahito prepare to fight each other. Kokichi manages to distract Mahito by sending multiple puppets out.

Kokichi uses this chance to get into his Ultimate Mechamaru puppet and uses it to force Mahito out of the building. Kokichi notices that Getou has put up a screen that has blocked him from escaping or contacting people. Kokichi thinks about how he has to contact Geto for help and to inform him about the Shibuya Plan. Kokichi also thinks about how he has to take care of Mahito first before he can deal with the screen. Kokichi thinks about how he can't be frugal with all the Cursed Energy that he has saved up and starts to fire blasts at Mahito. Mahito manages to dodge all Kokichi's attacks and grab a hold of Ultimate Mechimaru, which Kokichi thinks about how Mahito will always be on the offensive and that he prepared for this situation. As Mahito attacks the Mechamaru directly, Kokichi thinks about how Mahito would be able to break the armor if he is not careless. While Mahito starts to transform again, Kokichi manages to launch a bomb that destroys Mahito's left arm. As Mahito is stunned, Kokichi uses this chance to sent Mahito flying into the ground. As Mahito figures out that the bomb is able to destroy his soul along with his arm, Kokichi takes this chance to rapidly attack Mahito. As Mahito manages to slip away, Kokichi notices that Mahito arm has returned but figures that Mahito has just made it look like his arm had regenerated. Kokichi then fires his Pigeon Viola technique, but Mahito manages to evade the techniques. Kokichi manages to hit Mahito into the ground again, and prepares to launch another technique.

As Kokichi thinks that he will be able to win and join his friends, but is shocked when Mahito uses his territorial expansion. As Mahito uses his idle mutation on Kokichi, Mechamaru falls to the ground. Mahito gloats and turns away, which Kokichi uses this chance to pierce Mahito's body. Kokichi thinks about how the technique he is using is Miwa's Simple Territory and how the technique was developed along with how it works. As Kokichi uses the technique on Mahito, Mahito's body explodes and his Territorial Expansion disperses. Kokichi then turns his attention to Geto and prepares to attack but Mahito suddenly breaks into the cockpit. Kokichi then tries to stab Mahito with his last Simple Territory technique, while Mahito lunges at him. After the fight is over, Mechamaru is slumped over the dam, while it is unknown was had happened to Kokichi.

On October 31, Kokichi manages contact with Yuji and explains his situation to them. Kokichi explains that he had died days before, that Gojo has been sealed, and this is a back up plan that he had come up with just in case something had happened to him. Kokichi also says that he can explain all this to them because he has ruled them out as moles. Mei Mei says that he could be mistaken about her not being the mole, which Kokichi responds that their are two Cursed Users following them. After keeping to see if they are being followed, Mei Mei suggests that they continue on to Gojo's location but Kokichi says that their is a screen up ahead that won't let them through. Kokichi tells them that Mei Mei needs to create an opening so that Yuji can head back up and head to Gojo's location. After explains how important Gojo is to humanity, the machine goes with Yuji to Shibuya.

Later, Kokichi has a machine watch the enemy and learns that the seal sealing Gojo can't be moved before Mahito destroys the machine watching them. Kokichi informs Yuji about what he had learned, and also talks about how their plan of attack with the other Sorcerers should be. Once Nanami meets up with Yuji, Kokichi explains the situation and what they should do which Nanami agrees with. After explaining the situation, Kokichi shuts down to save energy.

During Yuji's fight with Choso, Kokichi makes contact with Yuji again. Kokichi informs Yuji about what Choso's technique is capable of and advises him to head into the bathroom. As Choso doesn't follow them, Kokichi manages to trick Choso into heading into the bathroom.
