Hey do you mind if I ask, do you think Miko felt out of place I'm Japan. Like she was putting on an act and when she came to the United States she was able to act as her true self?
So I re-watched TFP, and probably one of the only times we got a glimpse of Miko's backstory was this bit from the Darkness Rising premiere (S1E2 I believe):
So, from the sound of things, Miko has a rather privileged upbringing. I'm guessing her parents work in the business field or somewhere elite for that matter for them to afford piano lessons and send her to an elite school, which is pretty typical here as someone who's currently living in Japan myself, and being able to speak to local youths in the area about something like this, and most agreed that they too had a similar upbringing.
For some who don't have that privilege like Jack, we think that sounds awesome, but then we get this response from Miko:
So, yeah, you're absolutely right about Miko feeling out of place and having to put on an act, probably because of her responsibilities (school, extra curriculars, school clubs, even going to school on a Saturday) and the pressure from her parents wanting her to go to a university (Bulkhead's conversation with her in the episode, "Deus Ex Machina"). Stuff like that sounds like a typical Asian stereotype, but it's true, sadly...
So, her jumping at the chance to study abroad in Jasper gave her freedom to really be herself, and it's something that she most likely didn't have back in Japan (possibly a societal thing too).
Things like: getting to wear what she wants to school instead of a uniform, being able to dye her hair, and not being bound by the shackles of her parents' presence, and feeling a little bit rebellious for once (possibly by the people she met at Jasper High prior to meeting Jack and Raf who knows).
This reminded me of a foreign exchange student from South Korea back when I was in high school in the U.S. and how he had that strict upbringing back home. Eventually, he became a jerk jock, became (for lack of a better word) "whitewashed," and occasionally got busted a lot, according to word of mouth at the time, and was eventually sent back home halfway of the semester 😬
Anyway...at least that didn't happen to Miko 😆
This is a long response, but I just have to share this. Thanks for your question!
