Koorogi (コオロギ Koorogi?) is a technician in Mary's Recovery House.


Koorogi is a young adult with dark skin and purple hair, which length arrives at his chest. He has freckles on his cheeks, along with black eyes. He's often seen wearing a helmet which ressembles a cricket's head, a coral coloured vest, having under a dark turquoise shirt that cuts to his stomach. Koorogi wears wireless headphones around his neck. He wears dark grey gloves, which on his left wrist has two bracelets. It is shown in chapter 10 that his larger bracelet is capable of technological proprieties. A purple sweater is wrapped around his waist. He wears baggy, dark grey pants with a red drawing on the left knee and light grey slippers. Two keyboards are attached to a 'rope' hooked his pants. Koorogi is also mostly seen having a smug smile.


Koorogi is shown to be clever, as he was able to repair Mira and even add skin folds, as she isn't the average android. He is also seen to be extravagant, with his helmet that ressembles a cricket, which his name translates to. He can panic during situations, as when he had to look for the other Yurizaki androids when the syndicate attacked. It is also shown that he has pride, especially when it comes to Four, as he was shown to be pretty angry when he was destroyed. Furthermore this could suggest that he takes great pride in his creations.


Recovery House[]

Kyōma Mabuchi[]

Koorogi doesn't get along with Kyōma, but will provide him with information when requested.

Mira Yurizaki[]

Koorogi get along quite well with Mira. It is shown at a few times that Koorogi is there when Mira has to get someting fixed, like when her head was torn off by a car by saving Sierra and the kids. He also brought with her modifications to her skin, so she can hide her coil and change her breast's size. He also took care of studying how she works, like the mysteries of her functioning, for example the utility of her tail.


Koorogi works for Mary as technician at the recovery house. There is a few hints in the manga that they might be blood related, meaning them being mother and son. It is shown in the manga (Volume 11, Chapter 83) that Mary is aware, possibly even worried of how Koorogi lacks of sleep and food. She also says how he has to come for dinner, giving a hint that they are living together as mother and son, and that she raises him, giving him food.


It is shown that Koorogi has confidence in Four's strength. He got furious when Four was broke in half, as it took a hit to his pride.


Details about Koorogi's backstory weren't given in the anime or manga.
