The Iroma have met up with the rest of the setting within the last 5 years. It's infeasible for a Cohronl to have a Yamataian name when their first contacts with other species weren't even with Yamatai. You also need to clarify that her age is listed in Yamataian/Nepleslian years, not Iromakuanhe years, because right now, it appears she would be closer to 30 in Yamatai (add a third of the listed age to get the rough age in Yamatai/Nepleslia).
In the physical description, you should remove the line "fairly conservative for an Iroma female". Many Iroma don't modify their bodies unless needed for a job or for health reasons, and plenty get by with none or almost no modifications at all. I'd also like to see something in the distinguishing features section. Doesn't have to be unique to the character, but what about them would make you able to pick her out of a crowd? Even being completely normal in every way is distinguishing in a culture where you CAN modify yourself.
The personality could use some work, to be perfectly honest. The first two sentences both need to be removed, they're history, not personality. The personality describes who Michiko is, the history gives the why, try to keep the two separate when at all possible. This section doesn't care about the why she is serious, just that she's serious, and in what ways. Does serious mean she's very no-nonsense, slap people upside the head for not doing something right, or is she just very focused and careful with her own actions? Naïve in what way? Iroma in the military still live pretty full lives, especially since many of the major cultures put so much focus on children.
I would definitely like to see more in the history though, especially for an Iroma who is apparently separated from her unit in the Vanguard. Speaking as someone who took part in the last plot, I don't particularly see the Vanguard leaving someone out there in a dead suit, since they would probably recover the suit even if the pilot was dead, to save the materials. And for the entire family to be dead, but there to be no mention of what killed them, or why that would have absolutely no affect on Michiko confuses me. Iroma live REMARKABLY long lives compared to a normal human, assuming nothing out of the ordinary kills them, so for every single person in her family to be dead before she's a quarter of the way through her life is definitely something that should be noted in the bio.
Looking at the skills, you need more detail on several of them. If you want to link to a standardized skillset, you can, but if you're actually writing them out, go into a bit more detail. She speaks Common and Makuori, but can she write in Common, a language that would only barely be penetrating into the lives of most Iroma now? Is she truly fluent in both languages, or does she only know enough Common to get by? Has she learned the technical terminology for other nations yet, or is her experience with strictly conversational parts? Technology Operations brings up the same questions. Where did she learn to use someone elses technology when it wouldn't have been used in the Vanguard, and she's just now being picked up? And what do you mean by common technologies? Technology operations normally ties into computerized systems, which, as a technician irl, I can tell you that it's generally required to spend months learning systems or taking classes to learn a different system.
Just in general, expand on the skills to clarify what you mean, and try to use less vague language. If you're going to write them out, rather than link, we actually need to know what she's capable of. Remember, your initial seven aren't the only skills you'll ever get, things like leadership are usually better left until you've shown in the RP that the character is a capable leader.
These two are just little nitpicks, but if you don't mind, please list both the Metric and American measurements for weight/height. The grand majority of our players are from the US, and a large portion of people don't remember the conversions off of the top of their heads, it's easiest just to include both. And if you would, put a little bit more in the likes/dislikes section. Think about real life, and put it to work. Are there foods that she absolutely adores or hates? Smells? Doesn't need to be comprehensive, but it's a fun tool for GMs and players to work with if you detail it a bit more.
Last bit, she'll still have a few things with her, even in her VANDR if she gets picked up by the Neps. Not everything, but at least her suit and some tools that would've been with her. Maybe a knife or sidearm.
The money should also be listed as 6000DA (Nep currency) or 12000KD (Iroma currency), not KS.
You've definitely got the baseline character here, but there is definitely work that needs to go into it. Making an Iroma is different from making most characters, because they ARE different and separate from the majority of the setting, but they're also really fun to play. It's worth the time to really make a good, in depth character.
