Jirai Kei (地雷系), meaning "landmine-type", is a Japanese
slang term used in a derogatory manner to label someone as "ticking time
bomb". Just like with a real landmine, they are not recognisable as such until making a wrong step that's triggering an explosion.
Below, the main characteristics of a landmine-type:
- emotional instability
- attention seeker
- easily
triggered
- manipulative
- obsessive
Since
2020, the term has also become the name of a stereotype and character trope along the lines of "yandere", which attributes the previously mentioned traits to girls who wear dark alternative fashion styles.
"There are many girls who
might look Jirai Kei at first glance, but in
truth that's just stereotyping them as a real
landmine isn't visible."
