Sailor Aluminum Siren's nickname 'nuka ni kugi'
Remember how Sailor Aluminum Siren was bragging to Sailor Lead Crow about her nickname?
How people on earth called her "Nuka Ni Kugi"?
And Lead Crow informed Siren that it wasn't a good thing.
I found it out it means "Rice brain."
Which is ironic cause Siren's a little bit of a ditz at times.
