Something I appreciate about each hero is their handwave-animation and how well it fits their character. If you compare Ramattra and Juno for example - Ram is more reserved/respectful while Juno has this cute little shake.
it does feel like her identity is she was born and raised on the Mars colony with her mom, so her first language is English. That's also why she's so stereotypically awkward since she rarely speaks and meets new people. Though, I do also wish she does speak cietnamese since every other character speaks their respective language :(
