There's 3 I can think of in Baten Kaitos who might be aspie...
1: Kalas
Kalas is a bit of a toughened up, albeit insecure outcast... he's very courageous and will go to any lengths to achieve his goal. He ain't too good in social situations, and has a tendency to be angry... possibly due to feelings of intimidation.
Has these illusional thoughts I'm sure of him thinking 'Can't feel or act like that it'd show weakness' which is quite an aspie thing to do... from my perspective. He wants a straight answer and it frustrates him when there's all this awkward detail in what others say.
I think Kalas may well be aspie... the sort of 'resistant to authority' type who exaggerates due to his own insecurities. He finds it very hard to trust people.
He also doesn't show much emotion besides frustration, and he'll never admit to it but deep down he cares for his companions.
2: Lyude
Lyude is also another real possible aspie - he's a bit opposite to Kalas in some ways - whereas Kalas covers up his insecurities with anger and frustration, Lyude is a very sensitive type. A polite guy who is very loyal... however he too has tendencies to find it difficult to trust people.
A bit of a pushover in some situations, but that didn't prevent him from becoming a high ranking Officer in the Empire... but his moral fibre left him a feeling of guilt and he couldn't stand the evil that was being displayed... he stood up for the rights of miners infront of the Emporer, which got him exiled and demoted to Ambassador.
He's very easily put down, and gets depressed quite easily. Although his talents in music are strong.
3. Mizuzi:
Some bizarre creature who's really quite strange lol. A genderless child of some ancient civilisation... incredibly manic and hyper... probably finds it hard to focus... would be difficult to hold a decent conversation with it... thinking about it though Mizuzi may be more ADHD than Aspie.
