I feel like no one understands why I like Misako but also wish she wasn't added in the first place so I'm gonna try to explain:
She was pretty much added just for exposition in S2. That was it. And the exposition could've easily been done by a character who wasn't Lloyd's mother who'd abandoned him
We never actually learnt why she abandoned Lloyd at Darkley's, like yeah bc she was researching the prophecy but surely Misako would've tried to ask Wu for help. And I personally think Lloyd was left there because the son of Garmadon should've had a lot of social power in a school for future evil masterminds (a problem I have with Darkley's as a whole)
We aren't told when or where she met Wu and Garmadon, or much about their friendship pre-relationship
We never hear about her upbringing
She disappears for whole seasons and is only brought back for plot convenience
She obviously cares about Lloyd and all the ninja but she was definitely forgiven too quickly
Overall, there are just like missing scenes that I think would've helped her develop as a character
TLDR; Lego fail to write yet another female character well
