Currently in Japan there is a reporter arrested by the FSB over espionage charges. Maybe true, maybe not but I can only see Japan-Russia relationship to get worse so....
Earlier this year there was a rumour stated by a magazine about a gk minidrama set to be released around 2028, but that is not official so take it with a grain of salt.
So revised and predicted timeline of GKLA:
Spring 2024: first movie
Fall 2024: LA series
Spring 2026: second movie
Winter 2026?: second series?
(Rumoured) Jan 2028: mini drama?
Summer/Fall 2028?: final movie?
I was actually scared that this was going to get delayed forever since the relationship between japan and russia was deteriorating around 2022 or so (guess why), but at the same time confident that it could still be done.
I trust in the production company.
