You have a point, but I feel like that would get old after a while. Eventually you need to raise the stakes or else you run out of story to tell.
i mean, Saving 80k gold for my Retirement is a Tragic Comedy and it can pivot between its Yuri Romance, Political Espionage, and FUNA-Nonsense very well
like Mitsuha uses an island in the middle of fucking nowhere as a prison for the spies trying to surveil her.
Edit: my point is you can have serious shit while doing funny shit. this series though has been the funny shit being surplanted by the serious shit, and i dont like that. i use saving 80k gold as example because Mitsuha very, very rarely drops the Jovial Teen Girl facade fully even while murdering people. The only times weve seen it go down completely is in the Albarn-Zegleus War, Albarn-Yamano War, and the Boarding School Hostage Rescue, and only the hostage rescue ends with Mitsuha still in Cold Fury.
