The Warriors of Hope believe that Kameko is a magical shapeshifting Demon that only mimics the shape of a stink bug. Her usual location is unknown.
Kameko is stated to be extremely weak and acts just like her owner. She has the ability to sense danger and loves her owner deeply.
Toko used to believe that Kameko is a special insect that can understand her feelings, but she is actually an ordinary insect.
Prior to The Tragedy
Kameko was a stinkbug found by Toko when she was younger. Toko is the only one able to stand her smell and Kameko was the only one who constantly hung around Toko. Due to having no other friends, Toko got extremely close with Kameko and believed that the bug was the only one able to understand her feelings.
After Toko left for Hope's Peak Academy, Kameko most likely stayed behind with Toko's parents.
During The Tragedy
Kameko was captured by the Ultimate Despair and became a Captive for Monokuma's first motive in the Mutual Killing incident of Class 78. She was apparently enclosed somewhere just like the other Captives.
She was later freed, only to become one of the Warriors of Hope's Targets in Towa City.
After becoming a Target, Kameko wanders around frequently so her usually hiding spot is unknown.
Toko and Komaru Naegi later find her Hit List entry and Toko starts to cry in relief when she finds out that Kameko is still alive. Komaru and Hiroko Hagakure explain to her that Kameko is a normal bug and thus unable to understand her feelings. Toko accepts this but nevertheless, misses her pet a lot and wishes to see her again.
Toko is Kameko's owner. Kameko appears to love her owner, hanging around her often. Toko is also the only one able to stand Kameko's horrible stench.
When Kameko's "Hit List" entry is discussed with Hiroko, Toko gets unusually emotional, showing just how strongly she cared for the bug. She is offended when Kameko is called a bug and she calls Kameko her dear insect friend, "a friendsect". She believes that Kameko is a special insect that can understand her feelings, but Hiroko and Komaru make her realize that Kameko is just a normal bug. Nevertheless, Toko misses her pet dearly and wishes to see her again.
Kameko is a Target for the Warriors of Hope. They see her as a Demon target and will do anything to kill her. Kameko appears to know that the Warriors of Hope are enemies and will release her poisonous gas to protect herself.
- Kameko is part of the reason why Toko smells bad all the time, and even when both Kameko and Toko are far apart, Kameko's gas is so potent that it lingers around Toko.
- Kameko is most likely a Brown marmorated stink bug.
- It is unknown what Kameko's relationship with Genocide Jack is.
- Kameko's name is derived from "kamemushi" (カメムシ; lit. "turtle bug"), which is the Japanese term for stink bug.
